How to Measure for Roman Shades?
Precise measurements are vital to achieve a perfect fit and smooth performance. There are two main mounting methods—inside mount and outside mount—each offering its own advantages
Two Primary Mounting Options:
Inside Mount (Figure 1):
Fits inside the frame for a sleek, built-in look and keeps the trim visible. Requires at least 2” depth for proper installation.
Outside Mount (Figure 2):
Placed outside the frame to hide flaws and create a bold appearance. Works for almost any window, even those with shallow or extra-deep sills.
Measuring for Different Mount Types:
Measuring for Inside Mount Shades:
Width: Measure the window frame's interior width at three locations—top, middle, and bottom. Use the narrowest measurement to guarantee the shade will fit properly inside the frame.
Height: Measure the height inside the frame at three points—left, middle, and right. Take the longest measurement to ensure the shade covers the entire window height.
Depth: Check the window frame’s depth to confirm there’s enough space for the mounting brackets and the shade.
Measuring for Outside Mount Shades:
- Width: Measure the width you need, ensuring it extends beyond the window frame to cover the trim and provide space for the brackets. It’s advised to add an extra 6 inches (3 inches per side) for improved light blocking and privacy.
- Height: Measure from your chosen top mounting point down to where you want the shade to finish, either at the window sill or lower. For better light control, consider adding 3 inches to the height above the window opening.
Please Note：
Use a Steel Tape Measure: For the most accurate measurements, opt for a steel tape measure rather than a cloth one.
Measure to the Nearest 1/8 Inch: Precision is essential, so avoid rounding off your measurements.
Check for Obstructions: Take note of any window hardware, handles, or other items that could obstruct the operation of the shade.
Factor in Mounting Hardware: Ensure there is enough clearance above the window for the mounting brackets, especially if you’re installing outside mounts.
How to Measure for Curtains?
Step 1:
Measure & Mark for Rod Installation
Existing Rod
Measure the rod length and record.
New Installation
Position the rod above and around the window frame based on your desired visual effect.
Height: Mount 6–10 inches above the window frame to create the illusion of taller windows. Mark lightly with pencil or masking tape.
Width: Extend 6–15 inches beyond each side of the frame for proper curtain stacking. Mark placement points accordingly.
Understanding the Standards for Curtain Fullness
Adequate fullness ensures a luxurious, voluminous appearance.
Pleated Styles
Built-in fullness of 200–230% delivers rich, structured volume.
Specific Ratios:
- Pinch pleat, tailor pleat, inverted pleat, goblet: 2.0x fullness
- Triple pleat, triple tailor pleat: 2.3x fullness
Step 2:
Calculate the Curtain Panel Width
Flat Top Styles
(Grommet, Rod Pocket, Back Tab, Tab Top, Flat Panel)Formula: Panel Width = Rod or Track Width × Fullness ÷ Number of Panels
Pleated Top Styles
(Pinch Pleat – Double/Triple, Euro Pleat – Double/Triple)Formula: Panel Width = Rod or Track Width ÷ Number of Panels
Ripple Fold Styles
Formula: Panel Width = Rod or Track Width ÷ Number of Panels（Note: Calculation uses top width. Bottom width will be approximately 2.1 times larger.）
*Rod/Track EstimationIf not yet selected, estimate width by adding 6–15 inches to each side of the window frame.
Step 3:
Calculate the Curtain Panel Width
1. Calculate the Curtain Panel Length
Flat Top Styles
(Grommet, Rod Pocket, Back Tab)
Panel Length = Distance from rod top to ceiling (or desired height above) + Rod to floor distance + Bottom finish length
Pleated Top Styles
(Pinch Pleat – Double/Triple, Euro Pleat – Double/Triple)
Panel Length = Desired top height to floor + Bottom finish length
2. Ripple Fold
Panel Length = Track bottom to floor distance + Bottom finish length
Bottom Length Options
Floating: Subtract ½ inch from floor length for clearance above floor
Kiss the Floor: No adjustment – panel meets floor exactly
Puddling: Add 2–4 inches for deliberate fabric pooling at floor
Please Note：
· Use a steel tape measure, measuring to the nearest 1 inch in width and length.
· Measure each window and doorway individually.
· Your custom drapery will be made to the width and length you specify.
