My wife found this company on line and asked me to get the measurements for the 9 blinds that we wanted to order. I provided the measurements "to fit" the window and was unaware that the company would deduct a portion of the measurement from the numbers I sent them. Upon their arrival, I discovered that each blind was approx 3/8 of an inch shorter than I ordered. I went to their websight and found one place where they said that they would deduct from the measurements to make them "fit". In my 50+ years of being a home owner and doing my own repairs, I have always ordered "to fit" rather than to "cut to fit" ....Nevertheless, it was my own fault for not going to the website myself. So just a word of caution to the older generation out there to read the entire instructions for measuring.
