How this works and common questions

About this tool

Each room is twice the length plus the width, minus the door openings you type. The extra percent is applied once to the total. Verify with your local code or a professional. Nothing is stored.

How it works

A room’s trim is 2 times (length + width), minus the door openings. Rooms are added, then the extra percent is applied once, half up to 2 decimal places. The other unit uses 1 foot = 0.3048 metres.

Rules

You choose feet or metres for every room. Extra is a whole percent from 0 to 100. Openings longer than the perimeter are rejected. Verify with your local code or a professional. Ballpark estimate, check before you buy or quote.
