Common Drapery Terminology---Basic Window Treatments Explained

A friends daughter whose wedding I sewed and organized a few years ago came over last night with her 'Hubby'... saying that the deal on the house they had bid on had been accepted.

The young couple was in seventh heaven. Their first house was a beautiful older home with lots of large windows overlooking Erie Lake etc....

Then came the reason for this unexpected visit... Would I be able to make the window treatments for their new home? Obviously I said sure... What type of curtains did they have in mind? Both of them hummed and hawed--- then admitted they had no idea what they wanted. Neither did they have any idea about the difference between a sheer, a semi sheer drape, curtain, swags etc... We agreed to meet next month, after the closing date of the house.

Looking to find my old binder (the one I used to use at my sewing shop that explained with pictures the many different styles of window treatments) gave me the idea for this hub.

The following list of styles and types of window treatments and their terms most commonly used are by no means all inclusive. But (there is that little three letter word again), reading through the following will at least give a good base to anyone delving into the looooong list window treatment options.

Let's start at the beginning:

Every home is different, every taste in style, colour and texture etc reflects the individuals personal likes and dislikes. To be honest, no-where does a personality come out and show-up more than in the interior deco of their living space.

The window treatments of a home have to perform many more functions than just simply look pretty and match the styles and colourings of the home, including the furniture.

Window treatments:

  • can create privacy
  • can frame a beautiful view or close out (hide) an unsightly one
  • can provide either an elegant, casual, subtle or dramatic background to the rest of the interior décor
  • can pull together the room with its furnishings
  • can be the focal point of any room
  • can either diffuse or augment outdoor lighting
  • can insulate against the cold of the winter, the heat of the summer
  • can protect the floor coverings and furnishings from the sun
  • can influence a home as much as any piece of furniture, therefore window coverings should be considered as "home furnishings"

Traditionally, windows were covered with three types of curtains:

  • a sash curtain to filter light
  • a draw curtain to block out light
  • an over-drapery which was purely decorative.

In today's world curtains, drapes, blinds, shades etc. all come under the 'window treatments' umbrella. Honestly, if it fits in with the décor, mood and style of the home everything and anything can work and is being used as window coverings and accessories.

i.e. a fishnet draped over a boat oar in the window of a nautical themed room.

Terms or Lingo of Window Treatment:

  • Curtain header, heading ... is the top of the curtain from where it is hung onto a curtain rod ... (i.e. pleated, pocket, grommet top, etc)
  • Drapery or curtain fullness ... the fullness of the draperies is really depending on a persons likes or dislikes and naturally the wallet too. The fullness is usually referred to as double, two and a half times or triple the width. This means the drapery is 2x, 2.5x or 3x the widths of the window. The standard for a lace, sheer and lightweight fabric is 2.5x to 3x and for medium to heavy weight fabrics 2x to 2.5x. Obviously the 3x / 2.5x the width will give a mightier, nicer and fuller look.
  • Tie-backs ... are used to hold the curtain or drape panels in place. The height the tie backs are positioned at will determine the amount of glass or window that is exposed or framed. It's good to know that the overall look of a window can also be changed by the use of tie-backs. i.e. Holding the curtain panels back from a high position will expose more glass which will give the window a longer look and obviously also let in more light. And vice versa holding the drapery panels back from a lower position will show off less window and thus give the illusion of a wider window but will let in less light into the room.
  • Railroading ... the width of the fabric becomes the length. Using fabric width-wise eliminates seams especially great for sheers, or when the pattern in a fabric is not easily matched when creating valances etc.
  • Casing also called Rod-pocket ... is a fabric pocket with open ends which encases a curtain rod.
  • Curtain or Drapery Drop also called Drop Length ... is the length of a curtain or drape from the top or hanging system to the bottom hem edge.
  • Tailored Curtains ... are named for their clean lines. These curtains can be found plain or with trimmed edges. Used alone or with a coordinating valance, they can hang straight or be tied back.
  • Layering... adding multiple treatments onto the same window; the first layer is usually the functional one, (i.e. a blind or shade) and the rest are decorative (i.e. one layer of plain sheers and one layers of heavy French lace)
  • Double fold hem ... the name says it all, on most curtains or drapes the hem is folded double. ---reason 1: the double fold is the extra weight of the fabric which will let the window coverings hang better and evenly. ---reason 2: the double fold can mainly become cosmetic... on an opaque fabric the double fold eliminates the cut line or folded-over raw edge to show through. On full length drapes it is customary to have a double hem anywhere from 6-8"/15-20cm hem and on short drapes 4-5"/10-12.5cm is enough.
  • Seam Allowance ... is the extra amount of fabric used for joining two pieces of fabric.
  • Selvage ... is the finished edge that runs along both sides of fabric lengthwise.
  • Facing ... is the extra layer of fabric used to strengthen a drape or curtain. (commonly used on tab-top curtains or under grommets)
  • Flat Fell Seam ... A seam that gives extra strength to a seam.
  • French Seam ... a type of flat seam which encases the raw edges of fabric. Used on sheer or very loosely woven fabrics.
  • Cut Length the length needed for the curtain or drape plus hem and header allowances.
  • Cut Width ... is the width plus the side seam allowances.
  • Finished Length ... the curtain or drape length after the header and the hem are sewn.

These next terms are related and needed when measuring:

  • Stacking space ... is usually referred to as the distance needed for drapes in a drawn open state on a traverse rod. With other words drapery made from a heavy velvet will need more space than the batiste sheers when open. This is important to know when you're determining the width of your drapes. If you don't want the drapes to obstruct any of the light let in by your windows then you would give the full amount of stacking space outside the window frame.
  • Overlap ... is the area where the drapery panels over-lap at the center again on a traverse curtain rod. The standard is to have a 3.5-4"/8.75-10cm overlap.
  • Center Draw ... drapes which draw open or close from the window’s center point, without an overlap.
  • One-Way Draw ... one panel of drapery designed to draw one way only, most commonly used if the window is not centered on the wall, closer to the corner.
  • Projection ... is the distance the bracket holds the curtain rod out from the wall.
  • Return ... is the amount of extra drapery needed to cover the drapery hardware also called 'Going around the corner ease' i.e. If your mounting bracket has a 4"/10cm projection and you want to cover the distance from the front center of the rod to the wall. (having drapes encasing a window can help hold out some of the cold in the winter) you will need to add another 4"/10cm to 4.5"/11.25cm to the width of your measurements.
  • Leading Edge ... is the spot where the curtain panels overlap in the center of a two-way traverse rod.

Curtain or Drapery Header terms (tops):

  • Rod Pocket ... is a space or pocket sewn at the top of a curtain into which the curtain pole rod is inserted. In turn a rod pocket drape is simply a flat length of fabric with a stitched 'pocket' at the top that will give the shirred look along a curtain pole with the extra width of fabric.
  • Pinch Pleat ... is a traditional drapery header and comes in many different styles such as Double pinched pleats, Pencil pleats, Goblet pleats, Box pleats, Butterfly pleats, Cartridge pleats ... etc. These pleats are what give the fullness to drapery and where they are attached to either a traverse rod or pole rod with rings by using drapery hooks or clips. Depending on the price tag of the drapes these pleats are either tailor made (each pleat is individually measured and sewn) or by using self-styling pleater-tape.
  • Self-styling Pleater-Tape toppers ... is a header created by using a tape that is sewn to the full width of the drape panel. These self-styling tapes are fitted with multiple lines of string which when pulled create different pleats or decorative gathers. Pleater-tape is most commonly available in white or ecru and comes in different weight or thicknesses. (i.e. light weight --- used for sheers or heavy weight --- used in drapes) and also comes in different widths starting at 2"/5cm going up to 5"/12.5cm.
  • Tab top curtains and Tie top curtains ... a casual way of hanging drapes onto the curtain rod. In both cases the rods used with tab and tie top are usually ornate and decorative.

Window Treatments: Names and Types!

Here is a list of the most common types or names and explanations:

One drapery panel, with rod pocket and hem

Curtain or Drapery Panel !

A curtain or drapery panel is one section of a window covering, usually unlined. A panel can be simply a piece of hemmed fabric that is hung on a rod from the top of the window. It can be floor length or end at or below windowsill. Some department stores such as Walmart... etc and catalogues stores such as Sears, Ikea ... ect. sell pre-made curtains by the panel, which in most cases is the widths of the fabric, edged and finished off with a header (top) and a hem (bottom).

Buying drapes by the panel is probably the most inexpensive way for window coverings as you can buy as many widths as your wallet allows.

Cafe Curtain!

The cafe curtains is a window treatment that covers the bottom half of a window. Most commonly cafe curtains are used in the kitchen on a cafe rod hung at the halfway point of a window. This allows for privacy but does not restrict light into the room. At times the cafe curtain is accompanied by a valance which can either be a shorter version of itself or a swag.

The fabric used for the cafe curtains really influences the feel of the room. Light to medium weight fabrics are best suited for this style of window treatment. From colourful solid sheeting to intricate lace, to cotton tea towels, to gingham plaid, to country eyelet or to the lightest of batiste all work great.

Some of the endless types of valances


A valance is a short curtain and comes in many many shapes and styles. Valances can be used on their own to cover the tops of windows, doors or along with sheers and drapes. They come in numerous types and styles with names like balloon, stagecoach, buttoned-up, tailored, scarf, ascot, ruffled, gathered blouson, banner, awning ... etc. Each style can give a different feel to a room from elegant to formal or casual.


Swags - are long left and right panels (sidepieces) that hang from the top of the window framing the top half of the window. Hung on a rod or attached to a mounting board they are used alone or in combination with small center attached valances or tiers.


In the world of window treatment, Window Jabots can also be called Cascades are a decorative narrow side-panel which is either a tailored, pleated or ruffled arrangement of lace or cloth. (Of old 'the jabot' was the frill or ruffle attached to the neck of a man's shirt or a woman's blouse) The drapery jabot is mainly used to finish off the sides of drapes or valances. There are numerous styles of jabots and commonly coupled with valance inserts or placed beneath a festoon.

Window Scarf - is a long rectangular panel of flowy fabric that is draped over a decorative curtain rod, swag holders, suspended from other specialty hardware or threaded through deco sconces. Most often used as a frame for a beautiful window and view.

One 'pouf' bishop sleeve drapes

Bishop sleeve !

A Bishop sleeve curtain is an elegantly pouffed side drapery panel that in most cases is allowed to puddle on the floor. One or two 'pouff'/s can easily be added to either a long swag or to a finished drapery panel. Depending on the height of the ceiling and the dramatics wanted, two pouffs can add that mighty look. The bishop sleeve drape looks really elegant on a floor to ceiling window especially if the room has 9-10'/108-120cm high ceilings. As an average an extra 18-20"/45-50cm needs to be added to the length of the drape to achieve that nice full rounded look of the bishop sleeve and another 18-20"/45-50cm for the puddling on the floor.

Priscillas with valance topper

Priscillas !

Priscillas also called Cape Cods - are a tier curtain with a rod pocket header which has been embellished with attached ruffles, embroidery, smocking along the bottom and inside edges and which are held open with tiebacks. Commonly made using a sheer, semi-sheer or opaque fabric. They can also come with a ruffled valance topper. They can crisscross or center-meet. Priscillas with their various types of top treatments create a pretty layered effect at the window.

Sheers great either straight or tied back

Sheers !

Sheers - A drapery panel made of a thin, translucent, diaphanous fabric, such as chiffon or voile. Sheers let in sunlight, they can be used alone or used underneath solid drapery panels. Sheer curtains can give windows a romantic, classy vintage look.

Thinking back, our Grandmas would never have considered creating window treatments without using the 'double layer'.... the thin and transparent sheers that stay closed at all times with a solid drape that was opened or closed for privacy or for the black-out effect.

Using sheers as decorative accents are second to none as they can provide a unique and stunning look and are available in many styles and designs, embroidered or elegantly plain, in every colour possible from pastels to deeper, darker shades.

Shades or Blinds!

Shades - also referred to as Blinds cover a long list of window coverings. (Some will disagree with me when I lump both shades and blinds into one compartment but.....) The reason I put them together is that both shades and blinds are created in the sewing world of materials that roll, gather, or fold up and down. Both can be raised for light & view and lowered for privacy by either spring action or via pull cord . Both come in many types made from fabric to bamboo to narrow slats of wood, faux wood or vinyl. Made from the right type of material both shades and blinds can also be solar-protective (UV ray blockers) and heat-loss-preventives.

Roman Blinds - is a window treatment style that consists of a fabric panel onto wich horizontal channels have been sewn at intervals down its entire length into wich wooden dowels or slats are inserted. The blind or shade is raised and lowered via pull cord which in turn gathers soft folds. Variations of the Roman Shade or Blind are made from soft light fabrics, even sheer. Minus the wooden dowels these have a dramatic effect when raised. Some called them Balloon drapes in the past.

Another 'lingo or term' commonly used with regards to window shades : Lath. The Lath - refers to the top of a shade that is most often attached to a 2"x1"/5x2.5cm piece of wood, which then is solidly mounted to either the window frame, the wall or the ceiling.

Roll-Up Shade - A roll-up shade is actually a roll of material on a spring-wound tube that hangs on your window. Although most of us remember them from the "old days" as being made of a vinyl, they now come in a variety of colors and fabrics. These are available ready-made or can be customized.

Cellular Shade - Pleated Shade - is a fabric or sometimes made of a stiff paper window covering that has an accordion design to it. these too are available ready made but can be carefuly covered with a fine material to customize the look.

Indoor Shutters, in wood or faux wood can be the focal point of any room, formal or casual
Indoor Shutters, in wood or faux wood can be the focal point of any room, formal or casual


Shutters are hinged solid or louvered panels that fold across a window. They're used to diffuse light while giving privacy. Shutters are also suitable for interior use and can add architectural interest to any room. Same as their exterior brothers they are attached to the window frames. Today's versions are built from the traditional wood, faux wood or out of some very durable vinyl and look super either painted or stained. Most often the interior shutters come with horizontal, tiltable slats within the panels which allow control over how much light is let in or blocked. Also great to use as air flow control when the window is open in good weather but also offers some super heat loss prevention in the winter months. Typically two shutter panels are used over a window unless the windows are tall and narrow in which case four panels work best. However on a small window just one panel works well too.


Drapery hardware is available in two types:

  • Basic utelitarian (usually a white painted metal), non-intrusive hardware that is used to hold drapery in place, easy functions, usually at great prices.
  • Decorative (used a lot in today’s home styling), the many varieties available make it easy to match the rod to the style of the drapery, to the type of windows and the general décor of the room. Elegant, simple, ornate all made to show off each and everyones unique taste in style.

The list of names, styles and uses of curtain rods is quite extensive. To confuse matters a bit more, what goes under one name here in Canada can have a totally different name in other countries. Most are self explanatory such as: Conventional traverse drapery rods, Traverse pole set, Flexible wood traverse rods, Wooden pole rods, Tension rods, Sash rods, Cafe curtain rods, Continental rods, Swag holders, Sconces etc...

Then there are:

  • End Brackets (grips that hold the drapery rod to the wall, window frame or ceiling)
  • Center Support (a grip mounted from above used to support drapery rods to prevent the rod from sagging in the middle
  • Finials (decorative end pieces on pole rods also called “pole ends”)
  • Holdbacks or Tiebacks (used to hold curtain window treatments to each side off the window when open)
  • Cleat (metal or plastic hook mounted at the side of the window to hold the cords of window shades or blinds.

I have trouble understanding cut to double fullness. If the track is 2200mm what would double fullness be?

Hiya Linda Edmeston, first off... thank you for reading and commenting.

To answer your question, of course its okay to do whatever it takes to make your drapes just the way you like them to look. Instead of dowels you might want to try cardboard... width and length cut to slightly smaller than the same size as your pleats.

Hello ZsuzsyBee thank you so much for a most helpful hub! I would like to know whether it is acceptable to insert thin wooden dowels into pinch pleats in order to keep them straight. My three-pleat pleats tend to fold in the centre.

Batting is a good idea. Sticky Mac-Tac is self-adhesived vinyl or plastic on a roll comes in all kinds of pretty designs, colour used to cover kitchen shelves etc. It also comes in clear I used to cover my children's paper-back school books in it for protection. Handy stuff when it comes to joining light weight things like styrofoam etc.Good luck with the project.

I'm so glad to hear about Lexi's progress. She is quite the little fighter. You're all in my thoughts and prayers.

Take care

I am going to try to cover the styrofoam with some batting and then cover with fabric. I don't know what sticky Mac-tac is. The windows are 15cm long. Thanks for the tips and I appreciate the offer of advice when I get going on it.

Lexi is doing very well this week and just last night, got on her knees while in bed. She used to love sleeping on her tummy with her little fanny up in the air and her face on the tile floor. We couldn't keep her in bed. I think she liked the coolness of the tile floor on her face. I think she is really showing some progress lately and we have become a bit more cohesive on outlining goals for her so that everyone is working on the same things. Obviously, we are continuing to do some physical exercise, but we are also looking at other things that she may be capable of, like waving or clapping her hands. I feel if we all work together, we will see some quick progress.

Hiya Connie, how goes the battle? From what your saying you're trying to construct a Valance or Cornice box... How big is this window? If you're going to cover the styro with a very smooth fabric no matter how hard you try the join will show through... to get away from the join showing you have to either sew a tight fitting sox for the styro -OR- use a sticky mac-tac on the front and back of the story -OR- use a boucle type of fabric. As far as for mounting it onto the wall... as styro is really light it will really only require a couple of angle irons for the "Box" to sit on, no curtain rod needed. On that note... Styro comes apart really easy too so be careful when you tighten the "box" onto the angle irons with screws.

If you need more help just email me and I will talk you through the whole process step by step.

hope this helps

take care

Hiya Journey*, how are you?After being in the sewing business all of my life my head seems to be filled with this type of knowledge. I'm thinking that if I make it all into hubs maybe I can clear a little spot to allow some new stuff to enter(hahaha) thank you for taking a look and for commenting

Yes, this was quite interesting,Zsuzsy. I have bought some fabric and flat styrofoam 2.5 cm thick by 30 cm wide by just over 7.5 cm long. Two of these will be taped together to make one long valance for my mother's window. I have never done it and actually am a bit scared to try it (afraid I'm going to mess it up!). I haven't decided the method to attach the valance. I had thought about using a 5.08 cm flat curtain rod and attaching the stryofoam to that (somehow), which I thought might make it more sturdy. Do you have a better idea?
