Paver Base Calculator

Estimate base stone and bedding sand volume, weight, and optional cost.

Quick guide

A paver base usually has two layers: compacted base stone + a thin bedding sand layer.
Use finished (installed) area and average depths for each layer.
Add a buffer for compaction, uneven subgrade, and edge cuts (often 5-10%).

How to measure for paver base

Measure the total patio/walkway area (length x width) and include any curves by splitting into rectangles.
Choose base thickness based on soil and use (walkway vs patio vs driveway).
Bedding sand is typically a thin layer—confirm your paver system recommendations.

Assumptions to double-check

Base stone density varies by product and moisture; supplier conversions (yards ↔ tons) vary.
Compaction reduces loose material thickness; plan for compaction and regrading.
Edging and slope/drainage can change the effective area and material needs.

Buying tips

Confirm the correct base material (often 3/4" minus) and bedding sand type with your local supplier.
Round up to delivery minimums and plan access for a dump/pallet drop.
If you have low spots, plan extra base stone to build grade before sand.
