How Much Road Base for a 6x14 Shed Base?
How much road base for a 6x14 shed base is a quick volume problem. 84 square feet at 4 inches comes to 1.04 cubic yards. Road base usually weighs about 1.4 to 1.65 compacted tons per cubic yard, so plan on roughly 1.6 tons.
Volume and tonnage calculator →The math for a 6x14 shed base
- Area: 6 × 14 = 84 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 84 × 0.333 = 28.0 cu ft.
- Cubic yards: ÷ 27 = 1.04 yd³.
- Tons: × 1.5 = 1.6 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 | 1.04 | 1.6 | 1.7 |
| 6 in | 1.56 | 2.3 | 2.6 |
| 8 in | 2.07 | 3.1 | 3.4 |
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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
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. Since the shed base carries a shed floor frame, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 1.7 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
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 10x20 area at 2 inches takes about 1.9 tons.
- Weight used here: about 1.5 tons per cubic yard.
Where estimates go wrong
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
