Material details

Excavation breakdown

Layer depth0.333 ft base + 0.083 ft bedding + 0.198 ft paver + 0 ft extra = 0.615 ft.
Excavation volume120 sq ft x 0.615 ft = 73.75 cu ft.
Cubic yards73.75 cu ft / 27 = 2.73 cu yd.

Gravel breakdown

Converted dimensions10 feet = 10 ft; 12 feet = 12 ft.
Area10 ft x 12 ft = 120 sq ft.
Depth conversion4 inches = 0.33 ft.
Volume120 sq ft x 0.33 ft = 40 cu ft.
Cubic yards40 cu ft / 27 = 1.48 cu yd.
Volume with allowance1.48 cu yd x 1.1 = 1.63 cu yd.
Density assumption1.48 cu yd x 2,835 lb/cu yd = 4,200 lb before allowance.
Waste allowance4,200 lb x 1.1 = 4,620 lb.
Final estimate4,620 lb / 2,000 = 2.3 tons to purchase.

Bedding sand breakdown

Area10 ft x 12 ft = 120 sq ft.
Depth conversion1 inches = 0.08 ft.
Raw volume120 sq ft x 0.08 ft = 10 cu ft.
Allowance10 cu ft x 1.1 = 11 cu ft.
Cubic yards11 cu ft / 27 = 0.41 cu yd after allowance.
Density assumption0.41 cu yd x 2,700 lb/cu yd = 1,100 lb after allowance.
Final estimate1,100 lb / 2,000 = 0.6 tons to purchase.

Paver breakdown

Project area10 ft x 12 ft = 120 sq ft.
Paver size12 inches x 12 inches = 1 sq ft per physical paver.
Effective moduleEntered paver dimensions are treated as the installed module, so coverage is 1 sq ft per paver.
Raw requirement120 sq ft / 1 sq ft = 120 pavers.
Waste allowance120 pavers x 1.1 = 132 pavers.
Recommended purchase132 pavers rounds up to 132 whole pavers.

What this project calculator estimates

This paver patio calculator combines the main material quantities for one rectangular patio: excavation volume, gravel base, bedding sand, pavers, and optional landscape fabric, edge restraint, and joint material.

One shared footprint

The patio length and width are entered once. The calculator derives the shared area and perimeter, then passes the normalized project dimensions into the material calculators used for gravel, sand, and pavers.

Assumptions you control

You can edit base depth, bedding depth, paver thickness, material densities, ordering allowances, package quantities, optional roll or section sizes, and the pricing basis for each priced material. Base and bedding requirements can depend on site conditions, climate, manufacturer instructions, and local requirements.

Optional materials

Landscape fabric, edge restraint, and polymeric sand or other joint material are optional sections. Fabric uses an approximate area-based roll estimate. Joint-material bags use the coverage rate you enter from the specific product and joint configuration.

What is not included

The material total is not a full installed project cost. It excludes labor, delivery, tax, tool rental, excavation labor, disposal, drainage work, and supplier-specific fees.

Worked example

A 10 ft by 12 ft patio is 120 square feet with a 44 ft perimeter. With a 4 in gravel base, 1 in bedding layer, 2 in paver thickness, and 1 in extra excavation depth, the total excavation depth is 8 in and the excavation volume is about 2.96 cubic yards. The same 120 square foot footprint is used for the gravel, sand, and paver material estimates.
