How to Measure for a Room Divider

You don't need to be precise to start — rough sizes get you a quote. But when it's time to order, here's how to measure properly. All you need is a tape measure and five minutes.

What you'll measure

For any opening, take two dimensions — width and height — but take each one in three places.

Width (in millimetres)

Measure the gap the divider will fill, wall to wall (or wall to where it'll end):

1. At the top
2. At the middle
3. At the bottom

Walls are rarely perfectly straight, so these three often differ by a few millimetres. Write all three down — don't average them yourself.

Height (in millimetres)

Measure floor to ceiling (or to the beam/soffit the frame will meet):

1. On the left
2. In the middle
3. On the right

Again, record all three.

Common mistakes to avoid

• Measuring in centimetres or inches. Always use millimetres — it removes ambiguity.
• Measuring the skirting, not the wall. Note if skirting boards are in the way; we allow for them.
• Forgetting the floor finish. If you're laying new flooring after, tell us — the height changes.
• Trusting one reading. The three-point method catches out-of-square openings that would otherwise cause gaps.

Take a photo

A straight-on photo from a few steps back is worth a hundred words. It lets us see skirting, flooring, the ceiling line and anything unusual — and it's the single most useful thing you can send with your measurements.

You don't have to do this alone

If you'd rather not measure at all, we offer a pre-production survey, and we double-check every order against your photos before anything is cut. Made-to-measure should be reassuring, not stressful.
