How Much Road Base for a 10x24 Shed Base?

A 10 by 24 foot shed base is 240 square feet. How much road base for a 10x24 shed base depends on depth: at 4 inches it is about 2.96 cubic yards or 4.4 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 10x24 shed base

  1. Area: 10 × 24 = 240 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 240 × 0.333 = 80.0 cu ft.
  4. Cubic yards: ÷ 27 = 2.96 yd³.
  5. Tons: × 1.5 = 4.4 tons.

About road base

Road base is meant to be compacted at close to the right moisture. Dry base rock does not lock up well; a light spray of water before rolling helps. Weight per yard is a planning number; the scale ticket at the yard is the real one.

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. For a shed floor frame, 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. 4.9 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 shed base as firm ground allows.

Where road base fits

Works well for:

  • Base under asphalt and concrete
  • Gravel roads and drives
  • Equipment and shed pads

Think twice for:

  • Drainage layers
  • Decorative surfaces
  • Surfaces that will stay uncompacted

Quick reference numbers

  • Per inch over 100 sq ft: about 0.46 tons of road base (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.6 tons.
  • Another size for comparison: a 10x20 area at 2 inches takes about 1.9 tons.
  • Weight used here: about 1.5 tons per cubic yard.

Common estimating mistakes

  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • 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.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
