How Much Pea Gravel for an 8 Foot Circle?

Volume and tonnage calculator →The math
- Area: 50.3 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic yards: 50.3 × 0.250 ÷ 27 = 0.47 yd³.
- Tons: × about 1.4 tons per yard = 0.7 tons.
The gravel calculator does this for any size.

Where round stone areas work
Circles show up around fire pits, under swing sets, around trees and as seating areas. Steel or paver edging keeps the round shape crisp and holds loose stone in place. Do not pile stone against tree trunks; leave a gap at the base.

Buying the stone
Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Pea gravel is small and rounded, comfortable underfoot, and needs edging because it rolls. The scale ticket is the real weight; tons per yard here is a planning figure.
Measuring the area
Measure length and width in feet at a few points and use the largest figures, since real sites are rarely square. For odd shapes, split the area into rectangles and circles, work out each one and add them together. Depth is the number most people underestimate: drive a stake, run a level string and measure down to the dug-out surface in several spots.
Tools for the job
For anything bigger than a small path, rent a plate compactor; hand tampers cannot match it. A wheelbarrow, shovels, a hard rake and stakes with string are the rest of the kit. Wet the stone lightly before compacting so it binds.
