About MeasuredBuild

MeasuredBuild is a set of free calculators that work out how much material a home or garden project needs. Each one shows the answer as you type, with the math and the sources on the same page.

Why you can trust the numbers

Every calculator is checked three ways before it goes live:

• Tested against hand-worked answers. Each formula is worked out by hand first, and the tool must match those answers. The site runs more than 100 automatic checks every time the site changes.
• Compared with other calculators. The same jobs go into well-known calculators, and the answers must agree.
• Sourced figures only. Numbers like how much concrete one bag makes come from a manufacturer’s data sheet, an industry body or the building code. Each one is linked on the page.

The full process is in the editorial policy.

Who runs it

Tasdid Siddique builds, tests and maintains every calculator.
