How Much Road Base for a 6x24 Shed Base?
A 6 by 24 foot shed base is 144 square feet. How much road base for a 6x24 shed base depends on depth: at 4 inches it is about 1.78 cubic yards or 2.7 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 6x24 shed base
- Area: 6 × 24 = 144 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 144 × 0.333 = 48.0 cu ft.
- Cubic yards: ÷ 27 = 1.78 yd³.
- Tons: × 1.5 = 2.7 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 | 1.78 | 2.7 | 2.9 |
| 6 in | 2.67 | 4.0 | 4.4 |
| 8 in | 3.56 | 5.3 | 5.9 |
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. 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. 2.9 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.
When to choose road base
Works well for:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Poor fit 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 12x24 area at 3 inches takes about 4.0 tons.
- Weight used here: about 1.5 tons per cubic yard.
Where estimates go wrong
- 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.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
