Man Measuring Window


The first decision that needs to be made before you measure your windows is whether you want to mount the blind on the inside or outside of the window frame.

Blinds mounted on the inside of the window frame provide a clean look. On an inside mount the headrail will sit back in the window casing so that it will emphasize the actual size of the window and it allows your window molding to be visible. If you want your blind to fit flush with the window molding you need to make sure you have enough depth in your window to accommodate the width of the headrail. So,horizontally across your window you will need 4".

Blinds mounted on the outside of the window frame provide the illusion of a longer and wider window. On an outside mount a blind can be mounted either on the window molding itself or above and beyond the window molding, usually from the ceiling if the diffwerence between nolding and ceiling is leass than 12".  An outside mount always provides for greater privacy and light control. An outside mount may be your only option if the window is not deep enough.

Measuring for Urmika Shades

Inside Mount 


  1. Measure exact window width at top, middle, and bottom.

  2. Use the narrowest width. Do not make any deductions - provide the exact measurements of the narrowest width. 

  3. Measure exact window height at left, middle, and right side.

  4. Use longest height. Do not make any deductions - 

Outside Mount


  1. Measure exact width where the blind is to be placed.

  2. Add at least 3 inches for overlap (1-1/2" per side) for optimum light control and privacy.

  3. Measure exact height from the top of the proposed headrail location to the base of the sill. If there is no sill, measure to where the blind is to reach.

  4. Add 1-1/2" to the height for optimum light control.
