Step 1: Measure the recess depth

Before width and height, we check the depth so Halo has room to fit. Minimum required: 3 cm (1.18 in).

Do you have any obstructions inside the recess?

Things like window handles, latches, locks, or cranks. It doesn't matter, Halo works with both.

Step 2: Measure the width, three times

Hold the tape horizontally inside the recess. Once at the top, once at the middle, once at the bottom.

Why three times? Almost every time, all three numbers come out the same. Sometimes they differ by a few millimetres, no big deal. Three quick measurements just lets us be 100% sure your blind fits. No hassle on your side, peace of mind on ours.

2Middle cm mm
3Bottom cm mm

ⓘ Include the mm too — every millimetre matters for a snug fit.

Step 3: Measure the height, three times

Hold the tape vertically inside the recess. Once on the left, once in the middle, once on the right.

Same reason as the width. Almost always identical, occasionally a few millimetres off. Three points takes ten seconds and means we know your blind will fit.
