Measuring Guides

Roller Blinds

Measuring for your new blinds is easier than you might think! All you have to do is follow our simple tips, double-check everything you do, and set aside some time to do it. Happy measuring!

This guide works for:
  • Standard Roller blinds
  • Double Roller blinds
  • Enjoy Roller blinds
  • Illusion Roller blinds

Standard Windows

Recess fitting

Measure the full width and height of the recess [the size of the hole if you like] and we will make the appropriate deductions to ensure a perfect fit.

  • Measure in 3 places for both the width and the drop. For the width, compare the measurement at the top of the recess with the smallest of the measurements you’ve taken – if the difference between those is less than 25mm, use the measurement at the top of the recess. If it is not, use the smallest
  • Don’t make any deductions, we’ll deduct from the width to ensure your blind fits perfectly (3mm for standard & double rollers, 10mm for Enjoy & Illusion).
  • Use a metal tape measure, cloth ones can stretch and give you inaccurate measurements
Top-Tip:

Check that your recess is deep enough to fit the blind into, also bearing in mind any obstructions such as handles (see table).

Standard Roller Depth
Top-Fix Face-Fix
50mm 70mm
Double Roller Depth
Top-Fix Face-Fix
120mm 105mm
Enjoy Roller Depth
Illusion Roller Depth

Exact fitting

Measure the full width and height of the recess [the size of the hole if you like] and add a little extra to the top and to each side, we will make the blind to the size you specify with no deductions

  • To minimize light leakage we recommend that the blind overlaps the window recess by at least 70mm at the top and 50mm each side
  • The overlap at the bottom of the blind is a matter of personal choice but please take into account obstacles such as radiators

Part-tiled recesses

If you have tiles part-way up your recess (often the case in kitchens and bathrooms) then the space between them is most likely to be the narrowest point in the recess.

Measure at the top of the recess and between the tiles. Compare the two measurements; if the difference is less than 25mm, use the measurement from the top of the recess.

If it is not, use the width between the tiles. You will need to top-fix or face-fix your blind if this is the case.

If it is not, use the width between the tiles. You will need to top-fix or face-fix your blind if this is the case.

Bay windows, half-bays & L-shaped windows

We have some handy guides already put together especially for roller blinds in bay windows, click on the links below to take a look!

Angled bay windows

You can use these same guides for angled half-bay windows, it’s the same principle.

Square bay windows

You can use these same guides for L-shaped windows, it’s the same principle

Unique Features

When you choose exact fitting for a roller blind you are given two further options, either fabric width or bracket-to-bracket width (these options are not available for Enjoy or Illusion roller blinds).

Fabric Width

Fabric width is exactly as it sounds, the width of the fabric itself. We don’t recommend measuring for fabric width if you’re fitting the blind inside a recess.

Bracket-to-Bracket Width

Bracket-to-bracket width is the full width of the blind including the fittings. This is approximately 35mm wider than the width of the fabric.

Vertical Blinds

Measuring your new blinds is easier than you might think! All you have to do is follow our simple tips, double-check everything you do, and set aside some time to do it.

This guide works for:
  • Standard Vertical blinds
  • Rigid Vertical blinds

  • Measure in 3 places for both the width and the drop, use the smallest measurement
  • Don’t make any deductions, we’ll deduct 10mm from the width and 15mm from the drop to ensure your blind fits perfectly
  • Use a metal tape measure, cloth ones can stretch and give you inaccurate measurements

Exact fitting

Unique Features

Some of our wooden and Venetian blinds come with a decorative pelmet, or valance, which covers the headrail. The blinds that come with pelmets are:

  • Real wood blinds
  • Faux wood blinds
  • Synergy Venetian blinds

The pelmet is cut to the size and shape that is most suitable for the fitting type you’ve chosen:

Pelmets for Recess Fitting

If you choose recess fitting we will make the pelmet for your blind slightly wider than the blind itself so that the pelmet is a tight fit at the top of the recess and to prevent gaps.

Pelmets for Exact Fitting

If you choose exact fitting we will make your pelmet a few centimetres wider than the blind and include side returns, so that the brackets are not visible either side.

Skye Roof

Finding the right size for your roof blinds couldn’t be easier, you don’t even have to measure! Simply enter the code found on the plate on your window and we’ll make a blind to fit that size.

Some window manufacturers make the window code less obvious than others. If you can’t find the code plate or size of your window, simply measure the width and drop of the visible glass then give us a call, we’ll usually be able to identify the size code from the glass size.

Top-Tip:

If you can’t find your window code, simply measure the width and drop of the visible glass and give us a call to place your order.
