Home Project Scale is a collection of free material calculators for DIY and home improvement projects. Every tool answers the same practical question: how much should I buy? Concrete, paint, mulch, epoxy, drywall, flooring — measured once, bought right.
Every calculator works in both imperial and metric units. Flip the toggle once and the site remembers your preference — enter feet and inches or meters and centimeters, and get results in cubic yards and 80 lb bags or cubic meters and 25 kg bags.
The formulas are based on standard industry rules of thumb: bag yields printed by manufacturers, coverage rates from product labels, and waste allowances used by tradespeople. They are estimation tools — always confirm final quantities against the specific product you're buying, since coverage and yields vary by brand.
The site is independent and doesn't accept sponsorships or paid placements. Found an error or want a calculator we don't have yet? Get in touch — corrections and suggestions genuinely shape what gets built next.
