Use our simple step by step guides and videos to find out how to measure your standard windows, angled bay windows and boxed bay windows. Measuring yourself couldn’t be easier, takes just minutes and will save you money!

All our blinds are made with a 5mm manufacturing tolerance (width & drop), this tolerance is separate to the deduction made for a recess size product.

Recess Size

Inside Window Recess

This is the measurement you need to make if the blind needs to fit inside the window recess. Measure the width and the drop in three different positions ensuring you provide us with the smallest measurement.

We will make any necessary deductions to ensure the blind fits neatly within the recess of the window.

Exact Size

Outside Window Recess

An exact size blind is also known as ‘pin width’ or ‘finished blind width’. This is the measurement you need to make if the blind needs to hang outside the recess overlapping the window. Decide how much you wish to overlap the recess at each side, we recommend at least 7.5cm at each side as well as the top and bottom so as to minimise as much external light as possible.

Measure the width and the drop in three different positions ensuring you provide us with the smallest measurement. We will not make any deductions from the measurements provided.
