About House Calculator Canada

Last updated: 2026-10-22

House Calculator Canada is a free set of planning tools for homeowners, DIYers and small contractors across Canada. We built it because most online calculators use US sizes and prices, which makes the results awkward to use at a Canadian lumber yard or paint counter.

Each calculator uses a standard trade formula, shows the answer in imperial and metric, and is followed by a guide that explains the maths, common mistakes and what to ask your supplier. Read the details on our methodology page.
