Garden Material Planner
Calculate how many patio slabs, decking boards or turf rolls you need. Enter your total garden area, select material type and waste allowance.
How It Works
Effective area = area × (1 + waste / 100).
Units needed = Effective area ÷ coverage per unit, rounded up to whole units.
Adjust “Custom” if your material’s coverage differs.
Patio vs Decking
Concrete slabs offer durability; timber decking adds warmth underfoot. See Best Patio Slabs 2025 and Best Decking Boards 2025.
Lawn Preparation
Remove weeds and level ground before turfing. Follow our How to Lay Turf Guide.
Maintenance Tips
Seal slabs annually; oil decking and mow turf regularly. Learn more in our Garden Maintenance Tips.
