Paver Calculator

Pavers, base, bedding, and rough cost.

Paver / Patio Materials Calculator

Estimate pavers, optional paver boxes, base material, and bedding sand from patio size, paver size, pattern, and waste allowance. The calculator covers the main shopping quantities for a simple patio or path.

Use either pavers per box or box coverage for purchase rounding. Estimate jointing sand and edge restraint separately for the product system you choose.

Base and bedding amounts are shown as rough volume estimates. Compaction affects base material only, and supplier-specific coverage tables should still be checked.

Paver patio planning guide

Paver projects need surface pavers plus base, bedding sand, edge restraint, cuts, and waste. A patio that looks simple on plan can require more material once falls, curves, borders, and cuts are included.

Use this calculator for patios, paths, and small paved areas where you know the area and paver size or box coverage. Keep the structural base estimate separate from the visible paving area so each layer can be checked properly.

Project checks before purchase

Add waste for edge cuts, curves, borders, and diagonal patterns.
Confirm compacted base depth rather than loose tipped depth.
Check drainage fall away from buildings and paved thresholds.
Buy spare pavers for future repair, especially for color-batched products.

Preparation matters

This is a material planning guide only. Soil preparation, compaction, drainage, geotextile, bedding, and edge restraint details should be confirmed for the site conditions before purchase.

Worked paver example

A 5 m by 3 m patio has 15 square metres of surface area. If each paver covers 0.04 square metres, the base count is 375 pavers. With 8% waste, the practical count becomes 405 pavers before box rounding.

Base and bedding quantities matter as much as the pavers. A deeper base is often needed for poor soil, drainage areas, or vehicle loads, while a simple footpath may use a lighter build-up. Confirm the base specification before ordering bulk material.

Paver calculator FAQ

Why can the result show either pavers or boxes?
If you enter a box purchase mode, the main answer becomes boxes to buy. Without a box mode, the main answer stays as pavers required with waste.

Does pattern change waste?
Yes. The calculator uses pattern-based waste defaults when you leave the waste field blank.
