How We Calculate This

Each standard UK turf roll covers approximately 1 m² (610 mm × 1640 mm).

Formula: Rolls = Area ÷ 1.0 m² (rounded up)

A wastage allowance (5% for a simple rectangle, 10% for curves, 15% for highly irregular lawns) covers trimming at edges and around obstacles. Set it under Advanced options.
