MaterialSheet turns measurements into shopping plans

Why it surfaced

MaterialSheet is unusually explicit about its assumptions: waste varies by material, paint gets no automatic waste allowance, and gravel uses a compaction allowance. The homepage also says the arithmetic is shown, projects remain in the browser, and share links carry the project without an account.

A free set of home-project calculators that converts dimensions into material quantities, cost estimates, package counts, and printable plans.
