Shades Measurement Finder
Step 1 What style of mount would you like?
Choose One
Inside Mount
Simply provide the most precise inner mounting dimensions. There is no need to manually deduct clearance space on either side. Drawing on our years of experience, we will accurately calculate the optimal operating space on both sides for you.
Outside Mount
Shades are installed over the window on brackets attached to the wall or window frame. We recommend adding a minimum of 2-4" to both measurements.
Measure the Window for Inside Mount
① Measuring Width
Due to potential irregularities in window shape, it is recommended to measure at three positions on the window: (A), (B), and (C). Use the largest of these measurements as the ordering width, rounding each measurement to the nearest 1/8 inch when ordering.
② Measure Height
To determine height, also measure three positions on the window: (D), (E), and (F). Use the largest of these measurements as the ordering height, rounding each measurement to the nearest 1/8 inch when ordering.
③ Measure Depth
Measure the depth at the top of the interior window cover to ensure sufficient installation space. This measurement also determines if flush mounting is possible—where the product sits flush within the window frame without protruding. Minimum depth requirements vary by product; check the product description for the minimum installation depth needed for interior mounting.
Measure the Window for Outside Mount
① Measure the Width
Measure the width to be covered, with a recommended overlap of 2-4 inches on both sides to ensure privacy and light blocking.
② Measure the Length
Measure the height. Select the position for installing the top track, then measure the height from the top track to the bottom of the window sill or awning. If you want sufficient storage space above the window and an unobstructed view, add X inches from the top of the window.(Choose to add based on your actual situation)

Can I measure just one single position?
Can I use a phone app to measure? What tools do you recommend?
No, phone apps are not reliable for precision and may cause significant errors. We recommend a steel tape measure (with a minimum scale of 1mm). Avoid soft tapes (easily stretchable) or leather tapes (high elasticity). When measuring, ensure the tape is perfectly vertical/horizontal against the window frame to prevent skewed readings.
For inside mounting, do I need to leave extra space in width or height to prevent the curtain from getting stuck?
Not necessary. Based on years of industry experience, we reserve optimal space during customization to ensure smooth operation.
Please note: Do not base your purchase on width/height dimensions you have reduced yourself!
Do I need to account for curtain pleats when measuring?
No need to leave extra space. Berissa automatically calculates the pleat ratio based on the curtain type. Simply provide the actual measured width and height of the window to avoid over-sizing from adding extra length on your own.
Can I buy new curtains using the exact measurements of my old ones?
We don’t recommend it. Old curtains may have deformed over time (e.g., shrunk or stretched), leading to inaccurate sizes. Additionally, the old mounting type (inside/outside) may not match the new curtains. We suggest remeasuring the actual window dimensions.
If I notice uneven walls (dents or bulges) during measurement, will this affect outside mounting?
Yes. Outside mounting tracks need to sit flush against the wall. Bulges (e.g., nails, peeling paint) can tilt the track, causing light leaks or poor curtain movement. Dents may create gaps between the track and wall. We recommend repairing the wall first before measuring.
Is measuring for motorized curtains different from regular curtains?
No, it’s the same. You only need to ensure the window depth is sufficient, as motorized tracks are wider than standard ones.
I’m not sure whether to choose inside or outside mounting. Do I need to provide measurements for both?
We recommend measuring and labeling both. Provide the inside mounting dimensions (net width/height of the window frame interior) and outside mounting dimensions (wall coverage area outside the frame). If you’re still unsure, contact the sulugood team—we’ll be happy to advise you.
