How much gravel for a 10×12 shed base?

Data checked October 2026

Short answer

A 10×12 ft pad at 4 in compacted needs 1.48 cubic yards in place — order about 3.1 tons of crusher run (2.17 cu yd loose) including 10% extra and compaction.

Volume: 120 sq ft × 4 in ÷ 12 = 40 cu ft = 1.48 cu yd.
Compaction: crusher run goes down loose about 5.3 in deep and tamps to 4 in, so order 1.33× the volume; compact in 2 lifts of no more than 3 in.
Weight: at 1.45 t per loose cu yd that is 3.1 tons; quarry factors for crusher run put it anywhere from 2.8 to 3.5 tons.
Bags: 118 bags of 0.5 cu ft (about $706) versus about $166 for bulk delivered.
Hauling: 1 single-axle load from the yard, or 7 trips in a half-ton pickup (1,000 lb payload) — a yard of stone weighs 2,900 lb.
10×12 is the most common shed footprint; frame the pad with treated timbers so the stone stays put.

What's it for?

Project

4 in compacted is the IRC base course under slabs; Quikrete places about 5 in and tamps it to 4. Under pavers, use the paver base calculator.

Material & depth

Material

Compacted bases for driveways, sheds, slabs and pavers. Stone plus fines packs hard — the default base material. Also sold as: crush & run, #411, 304, DGA, ABC, GAB, CA-6, 21A, 2A, flex base, Class 2 AB, 3/4 minus.

Order loose, finish compacted

Spread about 5.3 in of crusher run and compact it in 2 lifts of no more than 3 in to finish at 4 in. That is why the order is 1.33× the finished volume — bag labels and most calculators skip this and leave you short.

Weight factors vary by quarry

Crusher run / #411 / road base: 1.45 t per loose cu yd (published 1.3–1.62).Your yard's scale ticket is the final word — enter its factor under “Weight factor”.

Bulk or bags?

Cheaper ✓ · incl. 1 delivery fee

At these prices bulk is cheaper from about 0.4 tons (15 bags). Bagged crusher run costs 7.7× the bulk price per yard here; bags make sense for small patches or where a truck can't reach. Your plan (delivered): $166.

Getting it home

Total weight: 3.1 tons · 6,285 lb
Dump truck: 1 single-axle load
Your pickup: 7 trips at 1,000 lb payload · about 16% of the order per trip

Pickup payload

Payload is on the Tire & Loading sticker in the driver's door jamb. Single-axle dump trucks carry about 5 tons; bigger orders come on a tandem (up to 18 tons).

Make the base bigger than the slab

Extend the base at least 6 in past every edge (Quikrete) — add 1 ft to each dimension above. Pouring concrete on it? The slab calculator covers bags and ready-mix.

How this was worked out

120 sq ft × 0.333 ft = 40 cu ft, ÷ 27 = 1.48 cu yd. × 1.33 for compaction × 1.10 extra = 2.17 cu yd, × 1.45 t/yd³ = 3.14 tons.

With bags at $5.98 and bulk at $29.00 per ton plus $75 delivery, bulk beats bags from about 0.39 tons. At 3.1 tons bulk is clearly the cheaper way to buy — bags only make sense if a truck can't reach the spot.
