Before you order

Use measured dimensions and supplier values

Read the outdoor planning guide

Measure the finished area

Break irregular projects into rectangles, calculate each section, and total the quantities before adding an allowance.

Use compacted thickness

Material depth should describe the finished compacted layer unless the calculator specifically asks for loose depth.

Confirm density and packaging

Local mixes, aggregate types, bag sizes and truck capacities vary. Replace defaults with values from the supplier quote.
