How Much Crusher Run for a 12x10 Shed Base?
How much crusher run for a 12x10 shed base: at 4 inches deep you need about 1.48 cubic yards, which is roughly 2.3 tons at 1.55 tons per yard. The shed base covers 120 square feet, so every inch of depth adds about 0.37 yards.
Volume and tonnage calculator →The math for a 12x10 shed base
- Area: 12 × 10 = 120 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 120 × 0.333 = 40.0 cu ft.
- Cubic yards: ÷ 27 = 1.48 yd³.
- Tons: × 1.55 = 2.3 tons.
The volume and tonnage calculator does this for any size.
Crusher run needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |

About crusher run
The fines in crusher run fill the gaps between stones, so it weighs more per yard than clean stone once compacted. Plan on rolling or plate-compacting it in lifts. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
Preparing the shed base
Level the footprint, extend the stone a foot or so beyond the shed walls for drip and drainage, and compact in lifts. A timber or block border holds the pad shape. This shed base sees a shed floor frame, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 2.5 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 shed base as firm ground allows.
Where crusher run fits
Good uses:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Less suited to:
- Drainage layers, since the fines slow water
- Decorative beds
- Spots where you want water to soak straight through
Quick reference numbers
- Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.8 tons.
- Another size for comparison: a 10x20 area at 2 inches takes about 1.9 tons.
- Weight used here: about 1.55 tons per cubic yard.
Where estimates go wrong
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
