Understanding Turf Quantities
Key concepts for accurate ordering and a healthy lawn
Measure Accurately
Measure the maximum length and width of your garden. If your lawn has an irregular shape, divide it into smaller rectangles, calculate each area, and sum them up.
Why Wastage Matters
Cutting turf to fit around curved borders, trees, or pathways creates offcuts that cannot be reused. A 5–10% allowance ensures you won’t run short mid-job.
Standard vs. Mini Rolls
Standard rolls (0.5m²) are quicker to lay for large, open areas. Mini rolls (0.24m²) are lighter and easier to manoeuvre in small or intricately shaped gardens.
Lay Promptly
Always lay turf within 24 hours of delivery. If delayed, unroll the turf and store it in a cool, shaded area, keeping it lightly watered.

Turf Calculator FAQ
Answers to the most frequently asked questions about measuring and buying turf for your garden.
Multiply the length and width of your lawn area in metres to find the total square metreage. Divide this by the coverage of a single turf roll (e.g., 0.5m² for a standard roll). Add a wastage allowance of 5% for simple rectangular lawns, or 10% for lawns with curved edges, paths, or flowerbeds, then round up to the nearest whole roll.
A standard turf roll typically measures 1 metre in length by 0.5 metres in width, giving a total coverage area of 0.5 square metres per roll. Mini rolls are also available, usually measuring 0.6m x 0.4m (0.24m²), which are easier to handle for small or intricate gardens.
For a simple, rectangular lawn with straight edges, a 5% wastage allowance is usually sufficient. For gardens with curved borders, pathways, trees, or flowerbeds that require cutting, increase the allowance to 10% to ensure you have enough turf to complete the job without running short.
Turf is a living product and should be laid as soon as possible, ideally within 24 hours of delivery. If you must delay, unroll the turf and store it in a cool, shaded area, keeping it lightly watered to prevent it from drying out or overheating.
Yes, it is highly recommended to remove the old lawn, weeds, and debris. The ground should be dug over, raked to a fine, level tilth, and lightly firmed before laying the new turf. This ensures the new roots can easily penetrate the soil and establish a healthy lawn.
