How Much Crusher Run for a 12x14 Shed Base?
How much crusher run for a 12x14 shed base is a quick volume problem. 168 square feet at 4 inches comes to 2.07 cubic yards. Crusher run usually weighs about 1.5 to 1.7 compacted tons per cubic yard, so plan on roughly 3.2 tons.
Volume and tonnage calculator →The math for a 12x14 shed base
- Area: 12 × 14 = 168 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 168 × 0.333 = 56.0 cu ft.
- Cubic yards: ÷ 27 = 2.07 yd³.
- Tons: × 1.55 = 3.2 tons.
The volume and tonnage calculator does this for any size.
Crusher run needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 3 in | 1.56 | 2.4 | 2.7 |
| 4 in | 2.07 | 3.2 | 3.5 |
| 6 in | 3.11 | 4.8 | 5.3 |
| 8 in | 4.15 | 6.4 | 7.1 |
About crusher run
Crusher run (also sold as crush and run, dense-grade aggregate or QP in some regions) mixes stone with stone dust. It compacts into a firm, nearly solid layer, which makes it the usual base under pavers, asphalt and gravel drives. 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. 3.5 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
Works well for:
- 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 4 inches takes about 3.8 tons.
- Weight used here: about 1.55 tons per cubic yard.
Where estimates go wrong
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
