This Ivory room darkening cordless roller shade measures 37 1/4"Wx72"L and is finished with a straight hem. It is proudly made here in the USA! The measurement is "tip to tip" meaning that is the finished size of the shade including the mounting pins at the very ends. When you measure for an inside mount ( you will be installing this shade on the inside of the window vs. outside of the window) you will want to enter the exact size of the inside of your window to the nearest smallest 1/8th of an inch. This will ensure the perfect fit and best light control. Please do not make any allowances when providing your window measurement(s). Providing any measurement other than the tip to tip measurement can result in a poorly fitting shade. When measured correctly, the shade will have a half inch space on either side. If mounting the shade on the outside of the window, continue to use the tip to tip measurement. Please supply that finished shade measurement in the size customization box. For outside mount shades you will add 1 inch to the width of where you want the "fabric" of the shade to cover.
