Stone, base layer, edging & stabilization takeoff
Walkways & patios typically use 2–3 in. of pea gravel over a stabilized base.
Without a compacted CAB sub-base, loose pea gravel gradually sinks into raw soil and needs frequent topping-off. This layer compacts down, so it's calculated separately from the pea gravel above it.
Includes a 10% cutting/overlap allowance and rounds up to full units. In length/width mode the perimeter is calculated automatically; in area mode, enter it above.
Stabilizer grids hold pea gravel level and firm underfoot, meeting ADA/firm-and-stable surface guidance for wheelchairs and strollers. Panels typically interlock, so figure includes a 5% cutting allowance.
Commercial landscape fabric needs seams lapped 6–12 in. so weeds can't push up through the joints — this adds a flat 10% allowance for that overlap plus edge trim. Roll length assumes a standard 100 ft/roll for the rolls-needed estimate.

Estimates are approximate and based on standard pea gravel and CAB densities. Always confirm quantities with your supplier before ordering, and check local requirements for accessible-surface stabilization grids.
Cost is what most people searching for a pea gravel calculator actually want to know first, more than the raw tonnage so it earns its own section here.
Pea gravel typically runs $30 to $60 per ton, or roughly $40 to $85 per cubic yard delivered, depending on region and whether it's bagged or bulk. For smaller patio or walkway jobs, bagged pea gravel from a home center often works out to a higher per-yard cost than a bulk delivery, so it's worth running both numbers before you decide. A ton of pea gravel typically covers about 80 to 100 square feet at 2 inches deep.
QuickTonnage's cost output updates live as you adjust area, depth, or price per ton, so you can test a few depth options against your budget before committing to an order.
Roughly 2,600–2,800 lbs per cubic yard, similar to other washed gravels, though the exact figure depends on moisture and source.
Typically $30–$60 per ton, with bagged pea gravel usually costing more per ton than bulk delivery.
Pea gravel is generally 3/8″ in diameter small, smooth, rounded stones, distinct from angular crushed gravel of a similar size.
About 80–100 square feet at a standard 2-inch depth. QuickTonnage calculates this automatically for your specific area and depth.
No, pea gravel's round shape doesn't compact or interlock well, which makes it a poor base material. A compacted aggregate base (crusher run or similar) belongs underneath; pea gravel works better as a decorative top layer.
