Always measure to the nearest 1 8 inch.
How do you measure your windows for blinds.
Use the smallest measurement as the window width to make sure that the blinds clear the sides of the window frame.
Decide if you want an inside mount or an outside mount before you begin the measuring process.
1 measure the width inside the window opening at the top middle and bottom.
2 measure the height inside the window opening from the top of the window opening to the window sill three times.
For the width of any set of blinds carefully measure the width of the window and add between 2 and 4 inches on each side.
Measure the height of your window opening in three places.
Then if possible add at least 3 inches to each side to ensure you re covering the light gap and to maximize privacy.
For all other blinds and shades use the longest measurement.
Steel measuring tape is much more accurate than cloth measuring tape.
For solar shades and vertical blinds record the width at the top of the window only.

When measuring for outside mount horizontal blinds start by measuring the window s width.
Measure the width inside the window frame at the top middle and bottom to allow for variances in construction.
