How to measure bay windows for custom shutters

A

Make a note of where you want the front of your shutter frame to sit inside your recess. You can mark the position in each corner at the top and bottom with a pencil. Remember you need minimum 65 mm of clearance.

B

Measure the exact inside width of your recess on your left, middle and right windows.

Begin on the left inside edge and measure into the corner across the top and bottom and write the smaller measurement down (see A to B in diagram). Remember to measure where the front of your frame will sit. Repeat for each window and write down the smaller measurement per window (see B to C and C to D in diagram). These three measurements will be your shutter frame width.

Don’t make any deductions for your corner posts as we’ll do it for you so that you get a perfect fit. Contact us if there's more than 10 mm difference between the top and bottom width measurements on any window.

For drops over 1500 mm measure from the bottom inside edge of your recess to the mid-point of where you’d like the midrail to sit and write it down. Position it in line with any horizontal mullions in the window. If you don't have a mullion, go for a position that's not at eye level.

B

For drops over 2100 mm you'll need two midrails. First measure from the bottom inside edge of your recess to the mid-point of where you’d like the first midrail to sit and write it down. Then repeat for where you’d like the second midrail to sit and write it down. Position them in line with any horizontal mullions in the window. If you don't have mullions go for positions that are not at eye level.

By default your midrail(s) will be spaced evenly if you don't provide measurements. So if you have mullions, the midrail may not line up nicely.

When you order online your midrail position(s) will be the same for every panel in your bay window.

Make a note of how many panels you'd like for each window in your bay and which hinge combination you'd like. You can use the guide at the bottom of this page for help and remember the less panels, the more light in your home.

For a window with three or more shutter panels you'll need to measure for your T post(s). Measure from the pencil mark in the left inside edge or corner across to the middle point of the vertical mullion your T post will cover and write it down. Refer to our hinge combination guide at the bottom of the page for T posts positions. Repeat if you want another T post and start from the left edge or corner again. Don't worry about making an allowance for the shutter frame as we'll do all that once you've ordered.

It looks incredible when T posts line up perfectly with mullions in your window frames. By default your T posts will be evenly spaced if you don't give us measurements. We recommend choosing the least amount of T posts possible to maximise light.

A

Check that the angles in your bay window corners are 45 degrees or 90 degrees (at a right angle). When you order you'll choose your angle option. If you're not sure or your angles are different contact us and we will help!

To check a 45 degree angle grab an A4 piece of paper. Fold over a corner to touch the opposite side of the paper and so the edges on both layers of paper line up. Place the paper into a corner of your bay window. If both sides are flush with your window then your angle is 45 degrees.

To check a 90 degree angle you can hold up an A4 piece of paper into a corner of your bay window and if the paper fits snugly you have a 90 degree corner.

B

Note down if you have any potential obstructions such as a dropped ceiling, bench seat or built in desk that butts up to your bay window frame at the top or bottom. They shouldn't interfere with your shutter frame, but you'll need to take your smallest drop measurement (see step 4). Feel free to call us if you have any questions.

For drops over 1500 mm measure from the bottom of your window frame or window sill to the mid-point of where you’d like the midrail to sit. Position it in line with any horizontal mullions in the window. If you don't have a mullion go for a position that's not at eye level.

For a window with three or more shutter panels you'll need to measure for your T post(s). Measure from the left outside edge or corner of your window frame across to the middle point of the vertical mullion your T post will cover and write it down. Refer to our hinge combination guide at the bottom of the page for T post positions. Repeat if you want another T post and start from the left outside edge or corner again.

Check if you have potential obstructions such as a dropped ceiling, bench seat or built in desk that butts up to your bay window. You'll need at least 40 mm clearance between the obstruction and your recess on all sides. This is so there's enough room for your shutter frame to attach to your wall around your window. If there's no clearance go for a recess fit and feel free to contact us if you have any questions.

For drops over 1500 mm measure from the bottom of your recess to the mid-point of where you’d like the midrail to sit and write it down. Then add 40 mm to the measurement you took to account for your shutter frame at the bottom.

Position your midrail in line with any horizontal mullions in the window. If you don't have a mullion, go for a position that's not at eye level.

For drops over 2100 mm you'll need two midrails. First measure from the bottom of your recess to the mid-point of where you’d like the first midrail to sit and write it down. Then add 40 mm to the measurement you took, to account for your shutter frame at the bottom. Repeat for where you’d like the second midrail to sit and write it down making sure to add 40 mm to the measurement you take.

Position your midrails in line with any horizontal mullions in the window. If you don't have mullions, go for positions that are not at eye level.
