How to estimate boards for a ceiling (with the calculator)

A quick walkthrough of the project calculator so your first order has enough boards — and not too many.

Estimating boards is mostly arithmetic, but it's the kind that's easy to get wrong at the lumber yard. Our project calculator is built to make this faster: you give it a room size and a profile, it gives you a board count with a waste factor baked in.

Measure the ceiling length and width in feet. Multiply them together for square footage. Then pick the profile you're using — the calculator already knows the coverage width after the tongue is taken away, so you don't have to.

We add a 10% waste factor by default. That covers offcuts on the ends of runs and the occasional board you decide you don't love. If your room has a lot of cuts (skylights, beams, oddly shaped corners), bump that up.

Run the numbers, then call us with the final board count. We'll confirm what's in stock and what we'd need to mill.
