How to Measure | Houston Window Treatments

Inside Mount
When mounting blinds or shades inside the
window casing or frame.

Simply measure the width and length in
three different places as shown in the picture
above. ( inside drywall to drywall or frame to
frame )

It is only necessary to give the smallest
of the three widths and the longest of the
three lengths to the closest 1/8" of an inch.

Enter exactly what your window frame
measures. Take NO deductions.

Ensure you have enough window depth.

The factory will take proper deductions to
the width of each inside mount blind to
insure proper fit in the window.

Outside Mount
When mounting blinds or shades outside
the window casing.

Simply measure the width and length of
the window in three places as shown in the
picture above.

Remember it's only necessary to give the
measurement to the nearest 1/8" of an inch.

For Horizontal/Vertical Blinds - You may want
to add extra inches to the width and length
measurements to ensure proper window
coverage. Ex: For Horizontal Blinds add ~3
inches to both width and length. For Vertical
Blinds ~4 inches to the width and ~3 inches
to the length.

The factory will take NO deductions on
outside mount blinds or shades.
You MUST add for overlaps

* NOTE - Always measure Width x Height *
