Turf Calculator

Calculate how many rolls of turf you need for your lawn, with the usual 5% allowance for cuts and shaping built in. Prefer seed? Switch modes and we'll price that instead.

UK turf rolls are typically 1m² each (about 1.67m × 0.61m). Order for the day you can lay it — turf keeps for only 24–48 hours rolled up.

How to use this calculator

  1. 1Measure the lawn's length and width in metres — for odd shapes, split it into rectangles and add the areas.
  2. 2Switch between turf rolls and grass seed to compare both options.
  3. 3Read the roll count (one roll covers 1m²) or seed weight, with the cutting allowance already added.
  4. 4Add it to your project board, then print or share the list.

Turf gives an instant lawn — lay it the day it arrives and water well for a fortnight.

When to lay turf

Best months: March–May and September–October — any frost-free month without baked-dry ground works.

Lay it the day it arrives and water daily for a fortnight. Stay off it for 3–4 weeks.

Worked example: family lawn

A rectangular lawn 6m × 5m is 30m². With 5% wastage that's 31.5m², so 32 rolls. The calculator also shows grass seed pricing for the same area — often a quarter of the cost.

Practical guidance

One standard turf roll covers 1m², so your roll count is simply your area plus 5–10% for cutting around edges, curves and obstacles — order the extra rolls rather than fall one short on laying day, because turf is perishable. Lay it within 24 hours of delivery, the same day in summer; rolled turf heats up and yellows fast on the pallet. Spring and autumn give the best rooting conditions, with the rain doing your watering for you.

Preparation decides whether the lawn thrives: strip weeds, dig over or rotavate, then firm and level 10–15cm of screened topsoil before a single roll goes down. Lay rolls in a staggered brick pattern with the joints butted tight, and walk on the laid turf via a plank rather than trampling the soil. Water thoroughly within an hour of laying and keep it moist for two to three weeks — the first mow comes when it reaches 5–7cm, taking off only the top third.

Common questions

One standard UK roll covers 1m². Add 5% for cuts and curves — 10% if your lawn is an awkward shape.
