How to Measure for Blinds

Follow this easy guide with step by step instructions on measuring windows for every type of blind.

What You Need

  • Metal measuring tape (preferred)
  • Pen & paper or notes in your phone

Decide Where Your Blind Will Hang

First of all you need to identify if your window has a recess.

Now decide whether you will hang your blind inside or outside of the recess (exact fit). You should check for obstructions inside the recess that could stop your blind from being fully extended, such as handles or fixtures.

Use a Metal Measuring Tape to Measure for Blinds

We recommend using a metal tape measure as this will give the most accurate results.

Recess Measuring

Measuring for Blinds Inside the Window Recess

If you want your blinds to hang inside the window recess, you must measure from wall to wall.

Measure in three places for both width and height. So, measure the width from left to right along the top, in the middle, and along the bottom of the window. Then, measure from top to bottom on the left, in the middle and on the right. You must use the shortest measurements to allow the blind to fit properly.

Exact Measuring

This is for blinds to hang outside the window recess, also known as the window facia.

If you want your blinds to hang outside of the window facia, you must measure the exact area that you want the blinds to cover.

If you are measuring for roller blinds, we recommend you add 35mm (3.5cm) to the width to accommodate the brackets. For all other blind types please add 100mm (10cm).

You should start your length measurement at the top of the facia and go down as far as you want the blind to hang when fully extended. This process will ensure the blind completely covers the entire facia.

Check Your Measurements Twice

By taking your window measurements a second time you can ensure you have it exactly right. At Unbeatable Blinds we make all your blinds to measure, so it’s important we have the correct measurements.

How to Measure for Perfect Fit Blinds

Check out our video guide below. Proceed to measure the visible glass area of each window. Ensure to measure up to the edge of the rubber bead. Do not include the rubber bead or seals in your measurement.

Similar to recess measuring, you should take three measurements for both length and width. We will use the shortest measurement.

Measure the depth of the window from the glass to the beading. You can use a credit card to help you. Place the card over the corner of the frame and use the metal tape measure to get your measurements.

Measure the distance between the edge of the beading to any surrounding obstructions, such as the handles. This should be more than 6mm. If it is less than 6mm, we have a cut around handle option that can be used for your window blinds, see how to measure for a rebate handle connector here. If you require a rebate handle connector you will need to notify us of your measurements, you can contact us on 0333 321 4050.

Measure the rubber beading, if it extends into the glass by more than 6mm, you should also phone us for assistance.

How to Measure for Skylight Blinds

Velux, Dakstra, Rooflite, Keylite and Fakro Roof Blinds

Measuring for roof blinds couldn’t be easier! Most manufacturers supply a handy plate with your skylight window that lists all the model information. This can usually be found on the top edge of your skylight window. Simply open your window so it is at eye level and your code should be located on the topside edge.

If you have a Velux blind, you will have a style code as well as a window code, you will need to enter both of these when purchasing your roof blind. For Dakstra, Rooflite, Keylite and Fakro blinds you will only require the window code.

If you cannot locate the window plate, don’t worry! Simply measure the width and drop of the visible glass size and use our handy guide to locate your code: Skylight Blinds – Convert Visible Glass Size to Codes

How to Measure for Quick Fit Blinds

Quick Fit Blinds fit neatly inside your window or door frame and cover the area of visible glass. This means that you will only need to measure the visible glass size.

Start by measuring from top to bottom, you should take this measurement 3 times across your window to ensure you are as accurate as possible. Take a note of the smallest measurement, this will give you your drop size.

Next you should measure from left to right, again taking this measurement 3 times down your window. Take a note of the smallest measurement, this is what you will use for your width size.

Ensure you measure accurately to the nearest mm and always measure each door or window individually, don’t assume that they are all identical in size.

Please Note: When measuring visible glass size, you should measure up to the edge of the rubber beading. Do not include the bead or seals in your measurements.
