blinds measuring guide

Guide to measuring roman, roller and venetian blinds

Ready made window blinds come in standard sizes so measuring for your window is very simple. Many blinds can be cut to fit exactly. All sizes are in centimetres with the width first followed by the drop.
All sizes are shown in metric measurements.

There are generally two places to fit your new window blind.

OUTSIDE INSIDE

Outside the window recess

This is the easiest way to fit your new blind if curtains will not be used on the window.
Width: Simply measure the width of the window and purchase the next largest blind up from this size.
Drop: All blinds have a standard drop so providing the drop of the blind is more than the window the blind can be fitted and trimmed if required.

Inside the window recess

If you wish to use curtains in conjunction with the blind or you just prefer your blind on the inside of the recess.
Width: Measure the inside of the recess and purchase the next largest blind up from this size. When you fit your new blind it can easily be trimmed to fit your exact window size.
Drop: as with blinds that are fitted outside the window recess all blinds have a standard drop so providing the drop of the blind is more than the window, the blind can be fitted and trimmed if required.
