How Much Pea Gravel for a 4x50 Walkway?
How much pea gravel for a 4x50 walkway: at 3 inches deep you need about 1.85 cubic yards, which is roughly 2.6 tons at 1.4 tons per yard. The walkway covers 200 square feet, so every inch of depth adds about 0.62 yards.
Volume and tonnage calculator →The math for a 4x50 walkway
- Area: 4 × 50 = 200 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 200 × 0.250 = 50.0 cu ft.
- Cubic yards: ÷ 27 = 1.85 yd³.
- Tons: × 1.4 = 2.6 tons.

About pea gravel
Pea gravel is small, rounded stone, usually around 3/8 inch. It is comfortable to walk on and drains well, but it shifts under car tires and needs a solid edge to stay put. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
Preparing the walkway
Dig the path a few inches below grade, compact the bottom, add fabric if needed and install edging on both sides so the material stays on the walk. For foot traffic, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 2.9 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the walkway as firm ground allows.
Good and poor uses for pea gravel
Works well for:
- Patios, walkways and dog runs
- Play areas with proper depth and edging
- Drainage around foundations when sized properly
Poor fit for:
- Driveways and steep paths, where it rolls and ruts
- Under pavers as a base
- Areas without edging
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of pea gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 8x16 area at 3 inches takes about 1.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
