What Ten Yards of Topsoil Actually Looks Like
Ten cubic yards is the point at which people get a surprise. It is either far bigger than they pictured, or — more often — smaller, because a number that sounds enormous makes a heap you can walk around in twenty seconds.
Concretely, ten yards of topsoil is:
- A pile about 14 feet across and 5 feet high — taller than you, roughly the footprint of a small car with the roof at head height
- 270 cubic feet
- About 12 tons, which is why the driveway question matters at this size
- 90 wheelbarrow loads
- Enough to cover 810 square feet four inches deep — a lawn about 20 by 40 feet
The pile, in numbers
How tall it stands depends on how the driver tips it and how wet the soil is. A dry, loose soil spreads out; a damp, cohesive one stacks:
| If it stands | It will be about |
|---|---|
| 4 ft high | 16 ft across |
| 5 ft high | 14 ft across |
| 6 ft high | 13 ft across |
If the driver rolls forward while tipping you get a ridge instead of a cone, maybe 20 feet long and lower. Same volume, different footprint — worth knowing if you are fitting it onto a drive.
To check a delivered pile against what you ordered: width across in feet, squared, times height in feet, divided by 100. A pile 14 across and 5 high is 14 × 14 × 5 ÷ 100 = 9.8 yards, which is ten. If it looks short, measure before you start spreading.
What it covers
| Depth | Covers |
|---|---|
| 1 in | 3,240 sq ft |
| 2 in | 1,620 sq ft |
| 4 in | 810 sq ft |
| 6 in | 540 sq ft |
| 12 in | 270 sq ft |
The work it represents
This is the part people underestimate. Ninety barrow loads is a full day for one person moving it a short distance, and considerably more than a day if the pile is at the end of a long drive. Two people with two barrows and a good run — half a day.
Spreading and raking ten yards level over 800 square feet is another half day on top.
Which is the argument for thinking hard about where the driver tips it. At ten yards, thirty extra feet of barrow run costs you well over an hour.
The truck
Ten yards is a tandem-axle dump truck — not a pickup, not a small tipper. It needs about 16 feet of overhead clearance to raise the bed, a firm surface, and room to reverse. Wires, low branches and carport roofs are the things that stop a delivery on the day.
At 12 tons of soil plus the truck, this is the load size where you should decide in advance whether it comes onto the drive at all.
What a yard or a ton of other materials looks like
Volume looks the same whatever the material: a cubic yard is a 3-foot cube, 27 cubic feet, and tipped from a truck it settles into a cone. The piles below use the same shape as the ten-yard pile above. What changes from material to material is weight — and that is the number that decides whether it fits in your truck.
| Load | Pile size |
|---|---|
| 1 cubic yard of anything | About 7 feet across, a little over 2 feet high |
| 3 cubic yards | About 10 feet across, 3½ feet high |
| 6 cubic yards | About 12 feet across, 4 feet high |
| 1 ton of gravel or crushed stone (0.7 yards) | About 6 feet across, 2 feet high |
| 5 tons of gravel (3.4 yards) | About 10 feet across, 3½ feet high |
The same cubic yard weighs very different amounts:
| One cubic yard of | Weighs about |
|---|---|
| Mulch | 0.2–0.4 tons |
| Compost | 0.5–0.8 tons |
| Topsoil | 1.0–1.2 tons |
| River rock | 1.2–1.4 tons |
| Gravel or crushed stone | 1.4–1.5 tons |
That is why a pickup can carry two or three yards of mulch but only half a yard of topsoil or stone, and why stone is usually priced by the ton while mulch is priced by the yard. The material calculators work out the volume, weight and trips for each one.
Is ten yards the right amount?
Work it out rather than guessing — the calculator takes your area and depth, and the coverage chart has the table. Ten yards is a common order because it is roughly a full truck, but a full truck is the supplier's unit, not yours.
If you need less, three yards is the more common minimum.
