Paver Calculator
How many pavers for a patio — and how much base? Enter the patio size and paver size and get the paver count plus the gravel base, bedding sand and polymeric joint sand.
10% for straight patterns, 15% for herringbone or diagonal.
Pavers for a 120 sq ft patio
594 pavers — 540 before waste · 0.22 sq ft per paver
Area: 120 sq ft (11.1 sq m). Base materials for this patio: 1.48 cu yd (1.13 cu m) of compacted gravel for a 4-in base, 0.37 cu yd of bedding sand for a 1-in layer, and about 3 bags (50 lb) of polymeric joint sand (roughly 50 sq ft per bag). Do not skip the base — pavers laid on bare soil settle and rock within a season.
Estimate. Paver sizes and joint widths vary by product — confirm the actual size and the current prices with the supplier before ordering.
Formula used: Pavers = (area ÷ paver area) × (1 + waste%). Gravel = area × 4 in ÷ 27 cu yd. Bedding sand = area × 1 in ÷ 27 cu yd. Polymeric sand ≈ 1 bag (50 lb) per 50 sq ft.
How this estimate works: A paver patio is counted from the area: divide by one paver's area, add waste for cuts at the edges, and you have the paver count. The base is just as important — a 4-inch compacted gravel base and a 1-inch sand bed are the standard build-up, and their volumes come from the same area times the depth, converted to cubic yards.
