DIYMeter is a free collection of DIY and home improvement material calculators. Our goal is simple: help you work out exactly what to buy before you start a project, so you waste less money, make fewer trips to the store and finish the job with confidence.
What we do
Each calculator turns your measurements into a quantity, a shopping list and a cost estimate. You can switch between feet and metres, and between US, UK, Canadian and Australian prices, on every tool.
How our calculators work
Every calculator uses standard industry formulas and typical product sizes, such as box coverage for flooring, paint coverage per gallon or litre, and common sheet, bag and board sizes. Each page shows the formula and a worked example so you can check the maths yourself.
A note on accuracy
Our results are estimates for planning. Product sizes, coverage and prices vary between brands and stores, so always check quantities with your supplier or a qualified professional before you buy or build.
