Measuring Guide For Window Blinds

Measuring for your blinds is a cinch - we've provided simple step by step guides for you to follow - it really couldn't be any simpler and it won't break the bank!

Please Note:

  1. All measurements should be provided in cm (unless the website gives you the option to provide the measurement in mm or inches).
  2. All our blinds are made with a 5mm manufacturing tolerance (width & drop).
  3. Always use a metal rule when taking the measurements. Cloth ones can strech giving inaccurate measurements.

Standard Windows

Recess Size

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.

Measuring Recess Drop

Top tip for blackout blinds

Our fabric experts recommend when ordering a blackout blind, you fit this outside the window recess using the ‘exact’ blind measurement thus ensuring as much external light as possible is blocked out.

Top tip for vertical blinds

The headrail is included in the drop of the blind therefore the louvres will be shorter than the drop.


Exact Size

Measuring Outside Width
Measuring Outside Drop

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.


Cloth Size (Roller Blinds only)

Cloth size is the specific width of the fabric itself. When mechanisms and brackets are installed the overall width of the blind will be larger.

Simply measure the width and drop you require the fabric to cover. We will not make any deductions from the measurements provided.

Should you want to buy new louvres to use with your existing headrail, simply measure the length of the existing louvres from the very top of the material to the very bottom. We will not make any deductions from the measurements provided.

Roof Blinds

Measuring for your roof blind is easy - most of the time you won't even need a tape measure. All you need to do is open up your window, and as you swing it you'll see a small metal patch on the top. This has the brand name of your window and a code. This will differ depending on the make of your window.

Velux

There are a number of letters and digits on the Velux plate, but you're only interested in the first six or seven. These are split into two sets. The first of these sets will be three letters long, for example "GGU", and is your "Window Type" code. Next to that code will be another one which is three or four characters long, and will look like "C01" or "PK35". This is the "Size" code. Simply select these codes on our website when you are filling out your order.

Fakro

On a Fakro plate you will see two numbers divided by a slash or an "x" like this: 78/98 or 78x98. These are the dimensions of your window in centimetres - the first number is the width, and the second number is the height.

Dakstra or Rooflite

Both Dakstra and Rooflite windows have one short code on the sash which is three characters long. It starts and ends with a letter, with a number in between, such as "C2A". When you are purchasing your blind, enter this code when you are prompted to choose your side.
