How to Measure for Your New Window Blinds

Measuring for your new blinds couldn't be simpler. It's an easy way to save lots of money and takes just minutes; you'll wish you'd done it sooner! All you have to do is follow our easy, step-by-step guides below.

Standard Windows


Recess Fitting

This is the measurement you need to take if you want your blind to fit inside the window recess. 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.

Tips

tick icon Measure in 3 places for both the width and the drop, use the smallest measurements

tick icon Don't make any deductions, we will do that for you to ensure your blind fits perfectly

tick icon Use a metal tape measure, cloth ones can stretch and give you inaccurate measurements

Face Fitting

Measuring for an Architrave

This is the measurement you'll need to take if you want to fit the blind to your window's architrave. In this case we will make the blind to your specified size with no deductions.

Tips

tick icon Measure the width from the outer edge of the architrave to the opposite edge.

tick icon Measure the drop from the top of the architrave to where you want the blind to finish.

Measuring for Square Set

This is the measurement you need to take if you want the blind to hang outside the recess overlapping the window. In this case we will make the blind to your specified size with no deductions.

Tips

tick icon Measure the exact width of the area you would like the blind to overlap. To minimize light leakage we recommend that the blind overlaps the window recess by at least 70mm at the top and 50mm each side.

tick icon The overlap at the bottom of the blind is a matter of personal choice but if you are measuring for a blind that will come down to the floor allow 10-20mm of clearance.

Measuring for Shutters

We like to keep things simple here at Blinds Online and our shutter measuring guide is no exception. Just follow these easy steps to measure your windows and you can save hundreds if not thousands of dollars on shutters making your home beautiful. Ready? Here we go...

Check for squareness

First of all, you need to check that your recess is pretty much square, making it suitable for our shutters. All you need to do is measure the recess diagonally from corner to corner on both sides. Then, compare the two measurements.

If the difference is 12mm or less, you're good to go. If they vary by any more than that, then unfortunately you won't be able to fit shutters in your recess. If this happens, don't worry, there are plenty more fish in the sea, or, in this case plenty more blinds and curtains to choose from across our sites.

Ready to measure?

First, decide where your shutters are going to sit. This can be at the front of the recess or outside the recess. Either way, measure at the place you plan to fit your shutters. Don't worry about making any deductions, we'll do all the maths for you.

Recess fitting

For a recess fitting you need to measure at the front of the recess. Measure the width at the top, middle and bottom.

Next measure the drop on the right, in the centre and on the left. Write down the smallest measurements, these are the sizes you will use to place an order.

Face fitting

For a face fitting you need to measure at the front of the recess as you would with a front of recess fitting. Measure the width at the top, middle and bottom.


Next measure the drop on the right, in the centre and on the left. Write down the smallest measurements.


Next, add 84mm to the width. This is the measurement you will enter.


Then, if you do not have a protruding windowsill, add 84mm to the drop. This will allow you to fit your frame evenly around all four sides of the recess.


If, however, your windowsill protrudes take the measurement for the drop and add only 42mm. This way the frame will run evenly around 3 sides of your recess and along the top of your windowsill.

Measuring for a mid rail

For taller shutters over 1400mm we put in a stylish midrail to give your shutters some support. The great thing about a midrail is you can customise its height so that it looks best. Usually, people tend to position their midrails at the same height as any transom bars on their window.

There are just a couple of small restrictions when customising your midrail. For structural reasons they must be a minimum of 380mm and a maximum of 1300mm from both the top and bottom of your shutter panel.


To position your midrail, simply measure from the bottom of your recess to the midpoint of where you want it to sit. If this is level with your transom bar, measure from the bottom of the recess to the centre of the bar.

tick icon Top Tip: See? Measuring for your shutters really is simple. To recap, here are the 3 golden rules to remember:

tick icon Measure both diagonals of your recess and make sure the difference is less than 12mm.

tick icon Always measure at the place you plan to fit your shutters.

tick icon And finally, measure in 3 places across the width and height and take the smallest measurement.
