What style of mount would you like?
Step 2 · Check The Depth
First, measure the available depth inside your window frame.
Minimum required depth is 2 1/2 inches. Check that the headrail and mounting hardware fit securely; if your frame is shallower, consider Outside Mount.
Your available depth is less than 2 1/2". An Outside Mount may be a better choice.
Step 3 · Find Your Width
Measure the inside width at the top, middle, and bottom.
Use the smallest of the three measurements, then subtract 3/8 inch for your ordering width. The headrail width equals the ordered width after this deduction. Record widths to the nearest 1/8 inch.
Step 4 · Find Your Height
Measure the inside height at the left, center, and right.
Use the largest of the three measurements as your ordering length. Length includes the headrail. Record heights to the nearest 1/8 inch.
Step 2
Before measuring, check the wall above your window for at least 2 inches of flat space for the brackets and headrail. Check trim, molding, doors, and other obstacles. If decorative trim projects outward, compatible projection brackets may provide clearance.
What's your window width?
Measure from the outer edge of the window frame or trim to the opposite outer edge.
Step 3
How far would you like the shade to extend beyond each side of the window?
If wall space allows, add 2–3 inches on each side to minimize side light gaps. With no trim, we recommend at least 2 inches per side.
Step 4
Measure the window height from the top outside edge of the frame to the bottom outside edge.
Step 5
How many inches above the window frame will the top mounting point be?
If wall space allows, mounting about 10–12 inches above the window can leave room for the shade to stack when raised. Choose the actual mounting height; 10–12 inches is a suggestion, not a required minimum.
Enter any coverage desired below the bottom outside edge of the frame. Leave this blank or enter 0 if the shade will end at the bottom of the frame.
ALL DONE
Enter the following ordering width × length for your Roman shade.
INSIDE MOUNT: Ordering Width = Smallest Inside Width − 3/8". Ordering Length = Largest Inside Height. The 3/8" deduction is already included here; do not subtract it again. Headrail width equals ordered width, and total length includes the headrail.
OUTSIDE MOUNT: Ordering Width = Window Width + Left Extension + Right Extension. Ordering Length = Window Height + Above-Frame Distance + any Bottom Extension. Both dimensions include the headrail. No width deduction is applied.
