Measuring for window treatments is much easier than most people think. Just follow these tips: Use a steel measuring tape. Measure to the nearest eighth of an inch - don't round your measurements. On your notes clearly indicate which measurement is the width and which is the height. It is very common to transpose measurements. We custom make your blinds to the sizes you give us. If these sizes are incorrect it is impossible to change the blind, so take your time and double check your measurements.

Horizontal Blinds:  Inside Mount (IB): Measure the opening width at the top, center and bottom, recording the narrowest width. Measure the height left, right and center, recording the longest height. We will make width deductions to allow for operating clearance.   Outside Mount (OB): Measure the opening width. If there is room, add at least 3" to each side of the window opening for minimum light gap and maximum privacy. Measure the opening height. Add a minimum of 2" in height to allow for mounting brackets above the opening and add your desired overlap for the bottom.

Vertical Blinds:  Inside Mount (IB): Measure the width top, center and bottom, recording the narrowest width. Measure height left, right and center recording the shortest height. We will allow for operating clearance. Outside Mount (OB): Measure the opening width. If there is room, add at least 4" on each side of the window opening to ensure minimum light gap. Measure the opening height . Add a minimum of 2½" to the height to allow for mounting brackets above the opening and add your desired overlap for the bottom.
