How Much Road Base for a 16x10 Shed Base?
How much road base for a 16x10 shed base is a quick volume problem. 160 square feet at 4 inches comes to 1.98 cubic yards. Road base usually weighs about 1.4 to 1.65 compacted tons per cubic yard, so plan on roughly 3.0 tons.
Volume and tonnage calculator →The math for a 16x10 shed base
- Area: 16 × 10 = 160 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 160 × 0.333 = 53.3 cu ft.
- Cubic yards: ÷ 27 = 1.98 yd³.
- Tons: × 1.5 = 3.0 tons.
The volume and tonnage calculator does this for any size.
Road base needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |

| 4 in | 1.98 | 3.0 | 3.3 |
| 6 in | 2.96 | 4.4 | 4.9 |
| 8 in | 3.95 | 5.9 | 6.5 |
About road base
Road base (also called base rock, ABC, or Class 2 base in different states) is a graded mix of stone and fines made to compact into a load-bearing layer. 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. 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. 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.
Where road base fits
Good uses:
- 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 8x16 area at 2 inches takes about 1.2 tons.
- Weight used here: about 1.5 tons per cubic yard.
Mistakes that throw off the order
- 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.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
