Turf rolls & slabs

MEASURE FIRST

How to prepare your inputs

Break garden areas into rectangles or triangles and enter the combined area. Obtain material depth, density and bag coverage from your supplier.

How this calculation works

Order coverage = length × width × (1 + allowance). Units round up by coverage per roll or slab.

Assumptions & exclusions

Allow for cuts and irregular areas. Supplier unit coverage varies. Excludes underlay, preparation, irrigation, delivery and labour.

Your next step

Confirm drainage, delivery access, finished levels, compaction and material suitability with your landscaper.

What if my shape or product is different?

Use dimensions and product data that match the stated method. For complex work, calculate separate sections or obtain a project-specific take-off. Do not apply simple geometry to structural or compliance decisions.

Why are quantities rounded up?

Whole bags, packs, sheets or cartridges round up to purchasable units. Decimal area or volume results are planning figures; confirm order increments with the supplier.
