Step 2 - Measure your window
In our series of easy to follow video guides we provide you with step-by-step advice on how to measure your window correctly and ensure that your shutters fit perfectly. We cover both portrait and landscape style windows for all three designs, full height, tier on tier and Tposts. To access our free, simple, video guides, enter your name and e-mail address and we’ll send the first video straight away.
Measure the width in 3 places across the width and across the bottom, middle and top, and then record all 3 sizes as you will need the smallest width to order from.
Again with the height measure the left, centre and right side of your opening, take note of sizes and use the smallest height to order from.

When fitting in a recess you will need to deduct some fitting clearance from the smallest width and height sizes that you take to ensure the frame fits and you have room for adjustment.
When fixing to your window, this fitting clearance creates a neat shadow gap that does not need filling.
If you’re side fixing, then the gap will need to be smaller and would require filling. After these deductions, the sizes left will be your actual order frame sizes.

If you have a rail on your window, it’s normally best to match a rail on your shutter. Middle rails that line up with your window handles allow the frame to be installed closer to the window as the louvres will tilt above or below the handle.
Sizes are required from the bottom up, so measure up from the window sill to the centre of where you would like your rail. Usually, this is the centre of the fixed rail. Remember to deduct any fitting clearance from your rail height.
Please note, rail heights can vary as much as half a louvre depending on the order height, louvre size and rail position, so they can be slightly lower or higher than your actual order height.

Tier on tier shutters come with a horizontal Tpost, so measure from the window sill to the centre of where you would like the centre of the Tpost to be.
The width of the Tpost is 60mm, so if you want the top of the Tpost level with a feature on your window, then remember to deduct 30mm so that your ordering to the centre of the Tpost.

Measure your Tposts from the left recess to the centre of each Tpost and remember to deduct any fitting clearance from the Tpost sizes when ordering.
If you have straight UPVC window handles, Tposts can be used to install the frame closer to your window as the handle sits behind the side stile of the shutter. Your handle needs to be within 64mm from the centre of the Tpost for the louvres to miss the handle.

Use a spirit level to check that the window is level, sometimes the window can be out of level, but still square in shape. You can check the size by measuring across the window diagonally.
If your window is out of level, allow more fitting clearance to create a larger shadow gap. This will provide more space to adjust the frame and disguise the fact the window is out of level. Any bumps in the plaster or out of level window reveals look less obvious with a larger shadow gap.

Measure how far the handle protrudes past the window frame to ensure the louvre blades don’t catch. Then, measure from the window frame, not the actual opening part of the window.
Remember, you can easily swap your handle to a low profile design, which can provide a much neater fitting. There is a video on our blog showing you how this can be done.
