Drapery Facts

Please refer to following information to help you order your Custom Drapery.  If you need help, please do not hesitate contact Design Assistance.


For Width (Rod Size) Full Drapery:  Full drapery covers the entire window in either a pair or a panel. Measure the Width of the window including trim and add a minimum of 4” to each side.  Rod sizes vary according to personal preference and design style.  If you are installing the Drapery under a Top Treatment your rod size should be 4” (2” each side) shorter than the width of the Top Treatment in order to mount the drapery under the Top Treatment.  Be sure to check if your Top Treatment has side legs as the inside width is 2" shorter than the outside width. Upholstered Cornices inside width is always 2" shorter than the outside width.  Be sure to consider your Finial length as they add width to a rod.  If you want and/or your drapery rod requires returns refer to the hardware specifications for the return size.  Our standard return size on Pleated Headings is 3 1/2".  Returns are optional as well as the return size.  If you are traversing (operating) your drapery we recommend a center overlap (pairs only) to close the light gap between the two panels. See "overlap" below.  This applies to cord draw or hand-draw traversing rod styles.  Refer to our FAQ's for more helpful information.

For Width (Rod Size) Side Panels Only:  Drapery Panels typically flank and/or go in between windows (filler panel) and are stationary (non traversing). Specify your rod size of how wide you want the panel to be.  For instance, if your rod size is 60" and you just want side panels covering 20" on both sides of the window, then you would order 2 panels with a width of 20". Refer to our FAQ's for more information.


For Length:  Measure the Length from the Drapery Rod to where you would like the drapery to hang.  Mount Drapery Rods a minimum of 3”
above the top of the window.  Where you mount the Drapery Rod varies according to personal preference, the space you have, and the length of the Drapery Rod Bracket you are using.  Be sure you have enough room to mount the Bracket.  And always take into account the ring size you are using when determining your length. 

  • Rod Pocket Headings measure from the top of the rod
  • Drapery on a Decorative Rod with Rings – Measure from the bottom of the Ring          
  •  Add 2"-4” to the length if you would like the drapery to “sweep” the floor
  •  Add 10” if you would like a “puddle” effect
  • "Stackback"  is the amount of wall space needed if you would like your Traversing (Operational) Draperies to clear the glass completely.  The easy rule of thumb in calculating your Stackback is to take the measure of the window and add 40%.  This will give you your rod size necessary to achieve complete stackback.  Many times you will not have enough wall space of either side of the window to achieve the full stackback.  In those cases, just go as wide as you can.  Certain Pleated headings stack more compactly than others.  See our Heading information below.
  • "Return" is the depth of where the drapery projects from the front of the rod back to the wall.  Returns always give a finish look to your drapery. Returns are your personal preference and are according to the type of drapery rod you are using.  Always refer to your drapery rod specifications for the return and/or projection size.  Our standard is to make pleated styles with 3 1/2" returns.  Other return sizes are optional according to your preference and hardware specifications.
  • "Overlap"  is where the two panels of center split draw drapery draw together in the center and overlap on a traverse rod.  The overlap is designed to close the drapery completely without any light gap.
  • "Undertreatment" is Drapery (usually Sheers) installed behind the main Drapery (Overdrape).  Underdrapes do not need returns on Standard Double Traverse Rods as the Overdrape returns cover both rod returns.
  • "Overdrape" is the Drapery installed over the Underdrape.  Standard returns for an overdrape is 6" on a Standard Traverse Rod.  It is always a good idea to check the Drapery Hardware you are using.   
  • Linings: Standard lining is Challis consisting of a blend of polyester and cotton. Premium lining is Suedeline (dim out) consisting of a blend of polyeter and cotton is is denser than Challis.  Suedeline will make your drapery heavier. 
  • Interlining is a cotton felt like fabric that is placed between the drapery fabric and the lining to provide extra fullness, protection, and energy efficiency.  Standard and Premium (Bump) are offered as options. Interlining also protects delicate fabrics such as Silk from the effects of the sun.  We recommend Interlining on all Silk Drapery and Faux Silks to provide extra fullness.  Our premium Suedeline lining is used when the interlined option is selected.  Please note: Using our Premium interlining "Bump" will make your drapes very heavy.
  • Rod Pocket "Header" is the 2" ruffle above the rod pocket.  Headers are optional.
  • "Flat Width" is the actual flat width of the drapery panel, not the rod size.   You will see flat widths referred to in our some of our drapery products. Flat width is also an option with our Grommet Drapery Header.  It is referred to as 1 x fullness.
  • Ring Count for Drapery.  See the Ring Count that you will need in the table below.  We suggest the same ring count if your Drapery has a Flat heading as well.
  • Lead and Stationary Edges:  This term is used when for decorative trim applications.  The lead edge is the inside edge of the drapery, stationary edge is the outside edge.  When trim is an option we will ask your for how many right and/or left panels you are ordering.  This tells us where to place the trim.  When pairs are ordered lead and stationary edge are self explanatory.

Drapery Heading information

  • French Pleats are pinched at the top and draw open most compactly as compared to other pleat styles
  • Goblet and Cartridge Pleat Styles are best in transitional and modern design schemes.  Cartridge Pleats also draw open most compactly than other pleat styles.
  • Pinch Pleats are the most Traditional style
  • Inverted Pleats give a tailored appearance great in transitional and modern design. Inverted Pleats compact the least out of all the pleat styles. 
  • Flat Heading is the same as a Rod Pocket, just without the pocket.  A Flat heading gives you the versatility of how many rings you want to use.  Flat headings require rings.  Rings allow you to hand draw the drapery if you desire.
  • Rod Pockets can be made with or without a header (the portion above the rod pocket that give a ruffle effect). Drapery can be installed through the rod pocket or drapery rings can be attached to the top of the drapery like a Flat Heading.  Rings allow you hand draw the drapery if you desire.
  • Grommet heading is the most modern style.  Draws open very compactly stacking in tight folds.  You may hand draw this style as well. Be sure you choose a rod diameter that is appropriate for this style, especially if you will be drawing the drapery to allow smooth operation.  We give you a 1 x fullness option for Grommet headings in addition to our standard 2 1/2 x fullness.  Many people do not want this style as full.  With a 1 x fullness factor the Grommet Drapery width (rod size) you specify is the "flat width".
  • Rod Pocket, Shirred Tab, and Tab Top are best as stationary drapery. Not recommended if you want to open and close the drapery.
  • Attached Valance style is made with the valance attached to your drapery.  The attached valance will be in the same heading style as your drapery.  The valance can be made in the same fabric as your drapery in in a contrast fabric.  Trim at the valance hem is an option.
