You forgot to tell us when you are measuring the inside frame to deduct the end caps from the width of the blind needed without getting the blind cut again. The end caps on each side of the blind are 1/16 inch, which you need to deduct 1/8 inch from the blind so it will fit perfectly inside the window.
