Do's

When measuring vertical blind slats measure the exact length of the slat when laid out flat from the top of the material to the bottom of the material.

Don'ts

Do not measure the full drop of the window because this measurement does not allow for the depth of the rail and the operating gap of the louvres.

N.B  Typically the length of a louvre or slat needs to be about 5cm shorter than the drop of the window to allow for the headrail, the hanger and the operating gap at the bottom of the louvre, if you order the louvre using the full drop of the window, the louvre will be about 5cm too long.

If there is any doubt give us a call, or email us.

To Recap

Remember only measure the length of the slat / louvre not the window drop.
