How Much Road Base for a 10x16 Shed Base?

A 10 by 16 foot shed base is 160 square feet. How much road base for a 10x16 shed base depends on depth: at 4 inches it is about 1.98 cubic yards or 3.0 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 10x16 shed base

  1. Area: 10 × 16 = 160 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 160 × 0.333 = 53.3 cu ft.
  4. Cubic yards: ÷ 27 = 1.98 yd³.
  5. Tons: × 1.5 = 3.0 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. 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. 3.3 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.

When to choose road base

Best suited to:

  • 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 14x28 area at 4 inches takes about 7.3 tons.
  • Weight used here: about 1.5 tons per cubic yard.

Where estimates go wrong

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • 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.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
