Measuring for Inside Mount Horizontal Blinds and Shades
General Measuring Notes:Always use a steel measuring tape. You need to measure every window, even if it is in the same room. Measure down to the nearest eighth of an inch. If you have any questions about measuring be sure to call our customer service department.
Note: Valances are made slightly larger than the window for Inside Mounts. This is to cover any gaps that may be present between the blind and window due to the bracket. If you are ordering a flush Inside Mount, please specify in the notes section of the order form that you want the valance smaller to fit into the window opening.
1. Measure the Width FirstMeasure the opening width at the top (as shown), center and bottom recording the narrowest width.
Do NOT take any deductions from that narrowest width. Our factory will take all the proper width deductions based on the window opening size you provide.
Be sure to note the width first, then height. All measuring notes we use on this site are width first, then height. Be sure you don't transpose those numbers.
2. Next, Measure the HeightMeasure the height left, right and center, recording the longest height. Our factory will take width deductions to allow for operating clearance.
All horizontal blinds and shades are made to the height you specify (no deductions taken) since they are made to rest on the window sill.
Remember, all of our blinds are custom made and can NOT be returned. Please be sure to measure accurately and request some free sample swatches if an exact color match is required.
Special Height Note: If you are measuring for our Horizontal Window Shadings product then you need to measure to the height in three places and take the shortest value.
