How do I measure for an inside mount shade?Updated an hour ago

Measure the width of the window at 3 points inside window casing – top, middle, bottom; use the narrowest measurement. Round up to the nearest ⅛”. The factory will make automatic deduction of ½”.

Measure height of the window at 3 points inside window casing – left, center, right; use the longest measurement. Use exact measurement to the nearest ¼”.
