How do I measure for a Clear Lean-to Pergola Cover (Sloped Roof)?
This guide explains how to measure your sloped-roof lean-to pergola for a custom-fitted clear Kuvr® cover, including each required measurement, where to take it, and how to record it accurately. There are 4 measurements to take, labelled A to D.
Important
Provide exact measurements with no extra allowance added. Kuvr® adds a standard tolerance of +25 mm (1 in) to the width and depth for a comfortable fit; no allowance is added to the height. You can measure in centimetres, inches, or metres — you choose your preferred unit when you configure the cover.
Please include photos
Photos of your sloped-roof lean-to pergola, taken from a few angles alongside your measurements, help us understand the exact shape and get your cover right from the outset. Including a tape measure in shot for scale is ideal.
The measurements
A — Overall width (outside of leg to outside of leg)
Overall width is the distance across the front, from the outside of the left leg to the outside of the right leg. Measure straight across at leg level.
B — Total height to top of front roof beam
This is the vertical height from the ground to the top of the front roof beam. Measure straight up at a front leg, keeping the tape vertical.
C — Total depth (outside of front leg to wall)
Total depth is the distance from the outside of a front leg straight back to the wall the pergola leans against. Measure level, parallel to the ground.
D — Total height to top of rear roof beam
This is the vertical height from the ground to the top of the rear roof beam where it meets the wall. Because the roof slopes up to the wall, this is usually taller than the front.
Frequently asked questions
What if my pergola has a roof overhang?
Measure the height to the top of the sloping roof beam directly above each leg, not to the outer edge of any overhang. The cover follows the beam line, so an overhang is not included in the height.
Should I measure the frame itself or leave a gap?
Measure the pergola frame itself, with the tape flat against the timber or metal. Do not add any allowance — we add a small tolerance during manufacture.
Can you cover pergolas with extra bays or an unusual shape?
Yes. Measure the closest layout shown here and send photos of your pergola. We confirm the exact pattern from your measurements and images before cutting.
