Types of Curtains: Styles, Headings, Fabrics and Functions Explained

Ask three people about the types of curtains and you may get three different answers. One describes how a curtain hangs, such as pinch pleat or eyelet. Another names the fabric, such as linen or velvet. The third describes what it does, such as blackout or sheer.

All three are right, because each answer describes a different feature of the same curtain. Most guides blend them into one list, which is why choosing curtains can feel harder than it should.

This guide separates them. It covers how curtains hang (heading styles and panel arrangements), what they are made of (fabrics) and what they do (light control, insulation and noise reduction). It also explains linings, lengths and how to combine these choices for a particular room.

How Curtains Are Classified

Every curtain can be described along six dimensions. Once you separate them, most curtain terminology starts to make sense.

Dimension	What it describes	Examples	Where it’s covered
Heading (style)	How the top of the curtain is built and attached, which shapes the folds below	Pencil pleat, pinch pleat, wave, eyelet, rod pocket, tab top	By Style and Heading
Panel arrangement	How many panels are used and where they sit	Single panel, pair, café, layered	By Style and Heading
Fabric	The material of the main curtain	Cotton, linen, velvet, polyester, voile	By Fabric
Function	What the curtain does with light, heat and sound	Sheer, light-filtering, room-darkening, blackout, thermal	By Function
Lining	Any layer sewn behind the main fabric, often what creates the function	Unlined, standard, blackout, thermal, interlined	By Function
Length	Where the curtain ends	Sill, apron, floor, puddle	Curtain Lengths

Take one curtain and describe it on each dimension:

• Heading: pinch pleat
• Fabric: linen
• Function: blackout, created by its lining rather than by the linen itself
• Length: floor
• Arrangement: a pair

Change any one choice and you have a different curtain. So “blackout curtains” and “pinch pleat curtains” are not competing types: one curtain can be both.

Some terms cross dimensions. “Sheer”, for example, describes a fabric (voile or lace) and a function (letting light through). Where that happens, this guide explains the term once and points back to it.

The Parts of a Curtain

These terms appear throughout the guide:

• Heading: the top section of the curtain. Its construction (gathered tape, stitched pleats, metal rings or a fabric pocket) decides how the folds form and what hardware the curtain needs.
• Face fabric: the main, visible fabric facing into the room.
• Lining: a separate layer sewn to the back of the face fabric. It protects the face fabric from sun fading, helps the curtain hang better, and can add light-blocking or insulating properties.
• Interlining: a soft extra layer between the face fabric and the lining. It adds body, insulation and a fuller look.
• Leading edge: the inner vertical edge that travels across the window as the curtain closes. On a pair, the two leading edges meet or overlap at the centre.
• Overlap: how far the leading edges of a pair cross each other when closed. A generous overlap helps stop light escaping down the middle.
• Hem: the finished bottom edge.
• Drop: the length of the curtain from its top to its hem. The term is widely used in curtain-making, especially in the UK and Australia.
• Hardware: what the curtain hangs from, usually a rod (also called a pole) or a track, which is a rail fitted with small gliders or runners.

Curtains, Drapes, Shades and Blinds: What’s the Difference?

All of these are window treatments, the umbrella term for anything that covers or dresses a window. They differ mainly in how they are built and how they move.

Curtains vs drapes. In British and Australian English, “curtains” covers both. In American English, “drapes” (or “draperies”) usually means heavier, lined panels that run to the floor and look more formal. American “curtains” tends to suggest lighter, often unlined panels of any length.

The difference is a matter of convention, not a strict technical rule; lining and length do most of the work. This guide treats drapes as a heavier, lined form of curtain rather than a separate category.

Shades and blinds are built differently. Most raise, fold or roll vertically, like Roman shades, roller blinds and Venetian blinds. Some, such as vertical blinds and panel-track blinds, slide sideways but use slats or flat, stiff panels instead of soft, gathered fabric. Either way, they fall outside this guide.

Valances and pelmets are fixed decorative pieces fitted above the window. They frame the curtains or hide the hardware but do not open or close.

Window treatment	Construction	How it moves	Relationship to curtains
Curtains	Soft fabric panels, gathered or pleated	Draw sideways on a rod or track	The subject of this guide
Drapes / draperies	Heavier, lined fabric panels, usually floor length	Draw sideways on a rod or track	A heavier, lined form of curtain (mainly US usage)
Shades and blinds	Fitted fabric, slats or stiff panels	Most raise, fold or roll; vertical and panel-track blinds slide sideways	A separate category, often layered with curtains
Valances / pelmets	Short fabric or structured piece above the window	Fixed	Used with curtains; not a curtain type

Types of Curtains by Style and Heading (How They Hang)

The heading is the top of the curtain, and it decides more than looks. It controls how the folds form, which hardware the curtain needs, how much fabric it uses and how easily it opens and closes.

Headings fall into two broad groups. Pleated headings (pencil, pinch, goblet, box, inverted, cartridge and wave) hang from hooks or gliders. Hardware-led headings (eyelet, rod pocket, tab top and tie top) attach directly to a pole.

Pencil Pleat Curtains

Pencil pleats are tight, narrow, evenly spaced folds, like a row of pencils standing side by side. They are made with a heading tape sewn to the back of the curtain; pulling the tape’s cords gathers the fabric to the width you need.

Because the tape holds hooks, pencil pleat curtains hang from a track or from rings on a pole. They suit both casual and traditional rooms and are one of the most common headings, especially in the UK. Very heavy or bulky fabrics can gather unevenly, so they work best with light to medium weights.

Pinch Pleat Curtains (Single, Double and Triple)

Pinch pleats are groups of folds stitched together at the base of the heading, then left to fan out below. The groups are called “fingers”: single, double or triple. The style is also known as a French pleat.

The heading is stiffened with a strip called buckram so the pleats hold their shape. More fingers mean more fabric, a fuller look and a wider stack when the curtain is open; double pinch pleats use less fabric than triple. Pinch pleats work on tracks and on poles with rings and give a tailored, formal finish.

Goblet Pleat Curtains

Goblet pleats are rounded, cup-shaped pleats at the top of the curtain, often lightly padded to keep their form. They create a grand, traditional look suited to formal living and dining rooms.

The trade-off is movement. Goblets do not fold neatly against each other, so this heading suits curtains that stay mostly open or closed rather than ones drawn several times a day.

Box, Inverted and Cartridge Pleat Curtains

These three headings give a structured, tailored top:

• Box pleats: wide, flat folds pressed into even rectangles. Crisp and architectural.
• Inverted pleats: the pleat is folded to the back, leaving a flat front with neat creases. They look formal without being fussy but stack less neatly, so they are mainly decorative.
• Cartridge pleats: cylindrical, column-like folds along the top, a clean and classic style.

All three suit rooms where curtains are mostly left in place. Choose them for the look rather than for frequent use.

Wave Curtains (Ripple Fold or S-Fold)

Wave curtains hang in continuous, even S-shaped curves along their whole width. The same heading is sold as ripple fold or S-fold, depending on the supplier and region.

The wave comes from the hardware as much as the fabric. Wave curtains need a dedicated wave track with evenly spaced carriers; they will not work on a standard pole or ordinary track. The result glides smoothly and stacks neatly, which suits modern interiors, wide windows and sliding doors. Lighter, fluid fabrics form the cleanest waves.

Eyelet Curtains (Grommet Curtains)

Eyelet curtains have large metal or plastic rings set into the heading, and the pole passes straight through them. “Grommet” is the more common term in the US. The rings create deep, even folds and a clean, modern look.

Eyelet curtains are made for poles, not standard tracks. Sources disagree on how easy they are to draw: some describe them as gliding smoothly, others as stiff to move. In practice it depends on the ring size, the pole’s finish and the fabric’s weight, so check the fit with your pole before buying.

Rod Pocket Curtains

A rod pocket curtain has a fabric channel sewn along the top, and the rod slides through it. This gathers the fabric in soft, slightly uneven folds and hides the rod. In some regions it is called a slot head or pole pocket.

Because the fabric rubs against the rod, rod pocket curtains are hard to open and close. They work best for stationary side panels, sheers and café curtains.

Tab Top and Hidden Tab Curtains

Tab top curtains hang from fabric loops sewn along the top, which slip over the pole and leave it visible. They have a relaxed, casual look.

Hidden tab (back tab) curtains put the loops on the back, so the front shows a flat or gently pleated heading and the pole stays mostly concealed. Both styles can drag on the pole, so they suit curtains that are not drawn often.

Tie Top Curtains

Tie top curtains are fastened to the pole with pairs of fabric ties knotted into bows or loops. The look is informal and soft, suited to bedrooms, cottages and children’s rooms. They work best with lightweight fabrics and are mostly decorative, since untying or sliding them is fiddly.

Single Panel, Pair, Café and Layered Arrangements

Arrangement is about how many panels you hang and where, independent of the heading:

• Single panel: one panel drawn to one side, useful for narrow windows or an asymmetric, modern look.
• Pair: two panels that meet or overlap in the middle. The most common arrangement and the most balanced.
• Café (tier) curtains: short panels covering only the lower half of a window, often hung from a rod across the middle. They give privacy while leaving the upper glass clear, which is why they are common in kitchens.
• Layered: two or more curtains hung together, usually a sheer behind a heavier curtain. How layering helps with light and privacy is covered under function below.

Heading Styles Compared

Fullness is how much fabric width is used relative to the width of the rod or track. A 2x fullness means twice as much fabric as the track is wide. The figures below are typical trade ranges; makers vary, so confirm with your supplier.

Heading	Look	Hardware	Typical fullness	Daily opening and closing	Formality
Pencil pleat	Tight, even gathers	Track or pole with rings	About 2x	Easy	Casual to traditional
Pinch pleat	Grouped fingers fanning out	Track or pole with rings	About 2–2.5x	Easy	Formal, tailored
Goblet pleat	Rounded, cup-shaped pleats	Track or pole with rings	Varies by maker	Best left mostly static	Very formal
Box / inverted / cartridge	Flat or columned, structured	Track or pole with rings	Varies by maker	Best left mostly static	Formal, tailored
Wave (ripple fold, S-fold)	Continuous S-curves	Wave track only	About 2–2.5x	Very easy	Modern
Eyelet (grommet)	Deep, even folds	Pole only	About 1.5–2x	Depends on fit	Modern, casual
Rod pocket	Soft, uneven gathers	Rod through a sewn pocket	Varies	Difficult	Casual
Tab top / hidden tab	Loops, visible or concealed	Pole	Varies	Fair; can drag	Casual
Tie top	Knotted ties	Pole	Varies	Difficult	Informal

Types of Curtains by Fabric

Fabric decides how a curtain falls, how much light passes through it when unlined, how it wears and how it is cleaned. Natural fibres (cotton, linen, silk, wool) tend to look softer and more textured; synthetics (mainly polyester) tend to be tougher and easier to care for. Many curtains are blends that balance the two.

Whatever the fabric, a lining changes a lot: it can make a light fabric darker, warmer and longer-lasting. Linings are covered under function below.

Cotton Curtains

Cotton is the all-rounder. It comes in every weight from fine voile to heavy canvas, takes prints and colours well and is usually easy to care for. Lighter cottons filter light; heavier weaves and lined cotton block more of it.

Cotton can shrink if washed hot, so follow the care label. It suits almost any room, including kitchens and children’s rooms where curtains need regular washing.

Linen Curtains

Linen is made from flax and has a natural, slightly irregular texture. Unlined, it filters light softly and gives a relaxed, airy look that suits modern, coastal and minimalist rooms.

Linen creases easily, which many people see as part of its character. Linen curtains blends reduce creasing. It can also shrink, so check whether a curtain is pre-washed and how it should be cleaned.

Velvet Curtains

Velvet has a dense, soft pile that catches the light and gives depth to color. Its weight and density help block light and soften sound, which makes it a common choice for formal living rooms, bedrooms and media rooms.

Velvet is heavy, so it needs sturdy hardware. It usually needs specialist or dry cleaning rather than machine washing.

Silk and Faux Silk Curtains

Silk has a distinctive sheen and an elegant drape, and is often used for formal rooms. It is also delicate: strong sunlight can fade and weaken it over time, so silk curtains are almost always lined, and they usually need professional cleaning.

Faux silk, typically polyester, imitates the sheen at a lower cost and stands up better to sunlight and handling. It is the more practical choice for sunny windows and busy households.

Polyester and Blended Curtains

Polyester is durable, affordable and low-maintenance. It resists creasing, fading and shrinking, and it is made in every weight from sheer to blackout. Many ready-made curtains are polyester or polyester blends.

The trade-off is texture: polyester can look less natural than cotton or linen, although modern “linen-look” polyesters narrow the gap. Blends such as poly-cotton or poly-linen combine a natural feel with easier care.

Wool Curtains

Wool is warm, heavy and naturally insulating, with a soft, matt finish that suits cosy, traditional or Scandinavian-style rooms. It drapes in full, weighty folds. Wool curtains are less common than cotton or polyester and usually need specialist cleaning.

Voile, Lace and Net Curtains (Sheer Fabrics)

These are the main sheer fabrics. They let most light through and give daytime privacy; how they perform is covered under sheer curtains in the function section.

• Voile: a soft, lightweight woven sheer, usually cotton, linen, polyester or a blend. It comes in many colours and drapes in fluid folds.
• Lace: a sheer with an open, decorative pattern, often floral or ornamental. Lace is a type of sheer, chosen for traditional or romantic rooms.
• Net: a knitted sheer with a coarser mesh, traditionally white or off-white. Net curtains are a long-standing British staple; voile is often seen as their modern alternative.

Curtain Fabrics Compared

Fabric	Drape and feel	Light when unlined	Durability	Typical care	Good for
Cotton	Soft, versatile	Filters to moderate	Good	Often washable; may shrink	Most rooms, kitchens, kids’ rooms
Linen	Relaxed, textured, creases	Filters softly	Good	Check label; may shrink	Living rooms, bedrooms, airy styles
Velvet	Heavy, plush, rich	Blocks much light	Good	Usually dry clean	Formal rooms, bedrooms, media rooms
Silk	Lustrous, elegant	Filters; needs lining	Delicate in sun	Professional cleaning	Formal rooms out of strong sun
Polyester / blends	Smooth; varies by weave	Sheer to blackout	Very good	Usually easy	Busy homes, sunny windows, rentals
Wool	Heavy, matt, full	Blocks much light	Good	Usually specialist cleaning	Cold rooms, cosy styles
Voile, lace, net	Light, airy	Lets most through	Fair	Usually gentle wash	Layering, daytime privacy

Always follow the care label: the same fabric can need different care depending on its finish, lining and construction.

Types of Curtains by Function

Functional types describe what a curtain does: how much light it lets in, how much privacy it gives, and how much it helps with heat and noise. For light, they sit on a spectrum.

A curtain’s function usually comes from two things together: the density of the face fabric and the lining behind it. A light linen with a blackout lining can block far more light than the linen alone.

Sheer Curtains

Sheer curtains let most daylight through while softening glare and blurring the view into the room. They are made from the sheer fabrics described above: voile, lace or net.

Their privacy is daytime privacy. After dark, with lights on inside, people outside can usually see in. That is why sheers are so often layered with a heavier curtain.

Light-Filtering Curtains

Light-filtering curtains are denser than sheers but still let diffused light through. They soften harsh sun and give more privacy than sheers, while keeping a room bright. Unlined cotton, linen and medium-weight polyester often fall into this group, which suits living rooms, kitchens and home offices.

Room-Darkening (Dimout) Curtains

Room-darkening curtains block most light but not all of it; some still passes through the fabric. In the UK and Australia the same idea is often called dimout. They suit bedrooms where a dim room is enough, and rooms where you want to cut glare on screens.

There is no single industry standard for how much light “room-darkening” must block, so performance varies by product. Look at the fabric against a bright window, or ask for a sample, rather than relying on the label.

Blackout Curtains (Blockout Curtains)

Blackout curtains use fabric or lining designed to stop light passing through the material itself. “Blockout” is the same thing under its Australian and UK name. They suit bedrooms, nurseries, shift workers’ rooms and home cinemas.

Even a fully blackout fabric rarely makes a room completely dark. Light leaks around the edges, over the top and down the middle where the panels meet. Eyelet headings and curtains hung inside a window recess tend to leak more. Fitting matters as much as fabric; see the FAQ on stopping light leaks.

The word “blackout” is also used loosely on product labels, so check what a curtain actually blocks before you buy.

Thermal Curtains

Thermal curtains use thick fabric, an insulating lining or interlining, or a combination, to slow heat moving through the window. They can help keep warmth in during cold weather and reduce heat gain from strong sun.

How much difference they make depends on the window, the climate and the fit. They work best when they cover the whole window, reach the sill or floor and sit close to the wall, so air cannot circulate freely behind them. Many blackout linings also add some insulation, but thermal and blackout are not the same thing; one does not guarantee the other.

Noise-Reducing (Acoustic) Curtains

Heavy, dense and layered curtains can absorb some sound, reducing echo inside a room and softening some outside noise. Products sold as acoustic curtains use extra-dense fabrics or acoustic linings for this.

No curtain soundproofs a room. Sound also travels through walls, glass and gaps. Think of these curtains as a way to make a room quieter and calmer, not silent.

How Linings Change What a Curtain Can Do

The lining is often what turns a decorative fabric into a functional curtain. It also protects the face fabric from sun fading and helps the curtain hang in fuller, neater folds.

Lining type	What it is	Effect on light	Effect on warmth	Effect on look and life
Unlined	Face fabric only	Depends entirely on the fabric	Minimal	Lightest drape; fabric exposed to sun
Standard lining	A plain cotton or poly-cotton backing	Reduces light a little	Some	Better drape; protects from fading
Dimout (triple-weave)	A tightly woven lining	Blocks most light; some passes	Moderate	Soft drape; often washable
Thermal lining	A lining with an insulating coating or layer	Reduces light	Good	Adds body
Blackout lining	A coated lining that stops light passing through	Blocks light through the fabric (edges may still leak)	Good	Adds body; usually white or cream, not black
Interlining	An extra soft layer between face fabric and lining (types include bump and the thinner domette)	Adds to the lining’s effect	Very good	Fullest, most luxurious drape; heavier

Linings are usually sewn to the curtain. Some are hung separately on their own track behind the curtain, so they can be drawn independently or washed on their own.

Layering Curtains for Flexible Light and Privacy

Layering combines two functions on one window, most often a sheer and a heavier curtain. The sheer hangs closest to the glass, and the heavier curtain hangs in front on a double rod or double track.

During the day, you close only the sheer for soft light and privacy. At night, or when you want darkness or warmth, you close both. Layering is the simplest way to get bright, private days and dark, private nights from the same window.

Curtain Lengths: Sill, Apron, Floor and Puddle

Length changes how formal a window looks and how practical the curtain is. There are four standard lengths, plus café curtains, which cover only part of the window.

The allowances below are typical ranges taken from retailer and maker guides. They vary, so check the finished length your supplier recommends.

Length	Where it ends	Best for	Watch out for
Sill	Just above the windowsill, often about 1 cm (½ in) clear	Kitchens, bathrooms, windows above counters, desks or furniture	Can look short on tall windows
Apron	Below the sill, commonly about 10–15 cm (4–6 in)	Windows above radiators, low cabinets or window seats	Can make a tall wall look shorter
Floor	Just clear of the floor, often about 1 cm (½ in)	Living rooms, bedrooms; the most versatile choice	Needs accurate measuring to look right
Puddle	Pools on the floor; guides suggest anywhere from a few centimetres to about 25 cm (10 in) extra	Formal, low-traffic rooms	Collects dust; awkward to open daily; a trip risk

Floor length is the safest default for most living spaces: it makes windows and ceilings look taller, and because the hem does not touch the floor, the curtain hangs straight and stays clean.

Sill and apron lengths solve practical problems: a radiator, a sink, a worktop or furniture right under the window. Apron length also helps warmth from a radiator reach the room rather than being trapped behind the curtain.

Puddle length is a decorative choice. It suits soft, heavier fabrics in rooms where curtains are rarely drawn and few people walk past.

For how to measure, start from the top of the rod or track. The heading style affects where the curtain actually sits, so follow your supplier’s measuring guide for the heading you choose.

How to Choose the Right Curtain Type

The easiest way to choose is to decide one dimension at a time, starting with what the room needs rather than how the curtain looks.

Start With What the Room Needs

1. Function: how much light, privacy and warmth do you need, day and night? This tells you whether you need sheers, light-filtering, room-darkening or blackout, and whether to layer.
2. Heading and hardware: how often will the curtain be drawn, and do you already have a pole or a track? This narrows the heading styles that will work.
3. Fabric and lining: choose a fabric for its look and care needs, then a lining to deliver the function from step 1.
4. Length and arrangement: decide where the curtain should end and whether you need a pair, a single panel or a café curtain.

Match the Heading to Your Rod or Track

Hardware decides which headings are possible:

• Pole only: eyelet, rod pocket, tab top and tie top.
• Track or pole with rings: pencil, pinch, goblet, box, inverted and cartridge pleats, which hang from hooks.
• Dedicated wave track: wave, ripple fold or S-fold curtains.

Tracks can bend around bay and corner windows and can be mounted on the ceiling, which poles generally cannot. Tracks with a pull cord or a motor also let you open curtains without handling the fabric. Motorized curtains tracks, powered by mains wiring or a rechargeable battery, work with pleated and wave headings and are useful for tall, wide or hard-to-reach windows.

Whatever the hardware, extending it beyond the window frame lets the open curtains stack against the wall instead of over the glass, so more daylight gets in.

Curtain Types by Room

These are common starting points, not rules. Your window, climate and taste may point elsewhere.

Room	Typical needs	Function	Heading	Fabric	Length
Bedroom	Darkness for sleep, night privacy	Blackout or room-darkening, often layered with a sheer	Pinch pleat, pencil pleat or wave	Any, with blackout or thermal lining	Floor
Nursery or kids’ room	Darkness for naps, easy cleaning	Blackout	Pencil pleat, eyelet or wave	Washable cotton or polyester	Floor or apron
Living room	Daylight, glare control, evening privacy	Sheer plus a heavier curtain, or light-filtering	Wave, pinch pleat or eyelet	Linen, velvet, cotton or blends	Floor
Dining room	Atmosphere, formality	Light-filtering or lined	Pinch, goblet or inverted pleat	Velvet, silk or faux silk, linen	Floor or puddle
Kitchen	Privacy, easy cleaning, clear worktops	Light-filtering or café	Rod pocket or tab top	Washable cotton or polyester	Sill or café
Bathroom	Privacy, moisture	Sheer or light-filtering	Rod pocket or eyelet	Polyester or other moisture-tolerant fabric	Sill or café
Home office	Screen glare, daytime light	Light-filtering or room-darkening	Wave, pencil pleat or eyelet	Cotton, linen or polyester	Floor or sill
Glass or French doors	Frequent opening, wide span	Varies; layering works well	Wave or pinch pleat on a track	Medium-weight fabrics	Floor

Ripple fold / S-fold	Other names for the wave heading
Stack-back	The space open curtains take up at the sides of the window
Voile	A lightweight woven sheer fabric

Final Thoughts

The types of curtains make sense once you see that each name describes one feature. Heading tells you how a curtain hangs, fabric what it is made of, and function what it does, with lining and length shaping the result.

When choosing, start with function, match the heading to your hardware and how often you will draw the curtains, then pick the fabric, lining and length. The comparison tables above are a quick reference when you are ready to decide.
