Step 1:
Deciding Between Outside Mount and Inside Mount



Valance is mounted on a spring tension rod and is held up inside the window frame.

► A great way to display beautiful craftsman molding around a window without covering it.
► The most budget-friendly way to mimic the modern look of a custom Roman shade made with designer fabrics.
► No screws and no drilling necessary.
► Minimally visible curtain rod hardware and no visible side brackets or decorative finials.
► Can be layered under heavy draperies or short valances.
► Can provide some privacy without sacrificing natural sunlight.

► Does not draw the eye up, so it may not make a room appear larger or taller.
► Requires at least 1-1/2" window depth to work.
► Most fabrics look best with blackout lining if the valance is directly up against the glass panes of a sunny window.
► Large fabric patterns may get cut off if the length is too short.


Valance is mounted on a decorative or standard curtain rod to the wall above the window.
You will need at least 3 inches of unobstructed wall space on each side for this option to work.

► Is usually long enough to be able to display large fabric patterns.
► Can be hung near the ceiling to draw the eye up and make a room appear taller and larger, as well as maintain a beautiful view to the outside.
► Can be paired with high-end decorative finials and modern endcaps.
► Handles sunlight filtering through the lining better, so may not always need blackout lining.
► More flexibility and room for error when measuring.

► Will cover some of the window molding.
► May show some of the rod side brackets when viewed from the side if window doesn't have any molding, unless the side flap upgrade is added.


Step 2:
Measuring For Faux Shade Valances


  1. Ensure your window frame has at least a 1-1/2" depth, and more if you plan on using your existing blinds behind your faux shade valance as well.
  2. Measure inside window frame width to within 1/4" at several areas of the frame.
  3. Using the smallest measurement, subtract 1/8" to 1/2" total to find the valance width you need to order. The faux shade valance needs this small amount of "breathing room" so that the folds can hang freely. Example: Order the 35.75" or 36" width if your measurement is 36.25".


  1. Measure your window width, from one outer edge to the other. Don't forget that your window molding is part of this measurement, too.
  2. Add this many inches to your measurement to determine the valance width you need to order:
    • If window has molding, only add 1" to 1-1/2" total to your measurement. Example: Order a 36.5" to 37" width if your measurement is 35.5".
    • If window does NOT have any molding, add 2" to 2-1/2" total to your measurement. Example: Order a 37.5" to 38" width if your measurement is 35.5".


Measuring Around Cabinetry, Nooks, and Tight Spaces


  • Determine how high the valance will hang, then ensure that there is at least 3" of wall space on each side of the window (marked as "A"). This is necessary to accommodate the curtain rod bracket and decorative finial or endcap.
  • Continue down, checking that there won't be any other obstructions along the entire length of the valance. We recommend at least 1-1/2" of space between the window and the cabinets and cabinetry trimwork on each side (marked as "B").
  • Order a valance width that will cover your window at least 1/2" on each side,
    but has enough room for the folds to fall freely.


  • If there is not enough room for the previous option, but your cabinets extend up, consider an outside mount with a tension rod.
  • The valance is still mounted up high to add height and open the room up, but the small endcaps on tension rods allow for more tight spaces around the window.
  • For this option, you want the space between the window and cabinets to be somewhere between 1/2" and 1-1/2" on each side (marked as "B").
  • Order a valance width that will cover your window 1/2" or more on each side, but has enough room for the folds to fall freely.


  • Frame mounts should only be used when none of the outside mount options above are possible, or your wall has tiles that shouldn't be damaged by curtain hardware.
  • For this option, measure the outer width of your window, including the wooden casing, then subtract the space that the curtain rod bracket will take up on each side (marked as a dashed line).
  • Look for small brackets that are no more than 1/2" wide to ensure your valance can still cover most of your window. The smaller the bracket, the better.
  • A bit of an overlap with the curtain rod bracket is fine if you're worried your window won't be well covered, but remember that this valance hangs flat across the top pocket and is not intended to be gathered.


Inside Mounts for Wide Windows

If you’d like to install separate inside-mounted faux shades for each section of your wide window, your individual window sections will need to be separated out by vertical mullions. Their width is irrelevant, but their depth is very important.

Just like the rest of the window must have enough depth to accommodate a spring tension rod for an inside mount, so does a mullion as well. Does the mullion have at least 1-1/2″ of smooth, flat depth for a rod to fit, and even more if you plan on using blinds as well?

If yes, you can order several valances for each section of the window. If not, consider a single valance from the options that we offer up to 120″ wide and hang it as an outside mount.




Deciding What the Best Length Is


Valances in rooms with 8' ceilings need to hang as high as visually possible, while in rooms with higher ceilings, a faux shade valance can hang lower.

Avoid the beginner's mistake of hanging your custom valance too low. If your valance is 16" long or shorter, it's normal for it to cover more of your wall space above the window than the glass panes if you want to achieve a magazine-worthy look.

For outside mounts, valance should minimally be 15" long and can cover as much of the window as you'd like.

Want to hang your faux shade valance lower? It's possible as well, although this is typically done only with window treatments that must cover at least a third of a short window.



Faux shade valance should ideally cover one-sixth to slightly past one-half of your entire window height. Be mindful that large fabric patterns may get cut off on short valances (16" in length or shorter).

We allow you to choose lengths up to 42" long for orders placed on (or up to 21" - 27" for orders placed on Etsy).


what About Bay Windows, Bow Windows, Corner Windows…?

No matter what kind of specialty window or group of windows you have, the same measuring instructions still apply.

  • For inside mounts, you still need to make sure your windows have at least 1-1/2-inches of unobstructed depth (excluding blinds) and you have the mullioned sections to support the tension rods in between each window section. Each mullioned section also needs at least 1-1/2-inches of unobstructed depth to make room for each tension rod.
  • For outside mounts, you still need to make sure your windows have at least 3 inches of unobstructed space each beyond the window frame. This translates to at least 6 inches of wall space in between bay window sections (this does NOT include the window frame), for example. Be mindful that you may need to use minimally sized end caps and/or corner connectors.
  • Frame mounts are not recommended for specialty windows like corner windows, bay windows, or bow windows unless there is abundant wall space in between each window section.


what About Sliding Glass Doors?

You’ll have to do an outside mount, choosing from the wide valances we offer up to 120″ wide.

Measure using the same outside mount instructions from above. Also, make sure the bottom of the valance covers the top frame of your sliding door while not obstructing household traffic.
