About Garden Calculator
Garden Calculator is a free set of UK garden calculators and plain-English guides. Enter your measurements in metres, and get exact quantities, honest costs and a ready-to-order materials list — no sign-up, no app, no catches.
What it is
Twenty-plus calculators for topsoil, mulch, turf, gravel, paving, fencing and more — plus a project board for your materials list and a professional estimator for tradespeople.
Who it's for
Homeowners planning a weekend project, keen DIYers, and working gardeners and landscapers who need quick, accurate figures on site.
Why it was built
Because too much money is wasted on the wrong quantities — a bulk bag too many, or one roll of turf short on laying day. Measure twice, order once.
The site was built with Paul, a full-time working gardener who retrained at Writtle College after a City career. Every guide and every depth figure comes off the back of real jobs — the same advice he gives his own customers. Meet Paul
