Wheelbarrow Calculator
A wheelbarrow calculator divides volume by 6 cubic feet per load and rounds up. A 10 × 10 ft area at 4 in deep is 33.3 ft³, or 6 wheelbarrow loads.
What your order looks like
A pickup or a small delivery will do it.
1.23 yd³ · 1.4 tons
17 wheelbarrow trips (2 cu ft each)
2 pickup loads (0.75 ton each)
1 small dump truck load (6 tons each)
Rules of thumb: A wheelbarrow trip is 2 cubic feet of heavy material, about 200 lb, a load most people can push. A pickup load is 0.75 ton, the payload of a full-size half-ton pickup (1,500 lb). A small single-axle dump truck carries about 6 tons.
Wheelbarrow calculator formula
A wheelbarrow calculator turns a volume into a count of barrow loads. The formula is loads = length × width × (depth in inches ÷ 12) ÷ 6, rounded up to a whole load.
The 6 is the cubic feet in one standard contractor wheelbarrow. The calculator multiplies the area by the depth to get cubic feet, divides by 6, and rounds up. There is no price or waste option here, so the cost shows as $0.
Worked examples
Example 1 is the default bed, 10 ft × 10 ft and 4 inches deep.
- Volume: 10 × 10 × (4 ÷ 12) = 33.33 cubic feet
- Loads: 33.33 ÷ 6 = 5.56
- Rounded up: 6 loads
Example 2 is a small mulch bed, 8 ft × 4 ft and 3 inches deep.
- Volume: 8 × 4 × (3 ÷ 12) = 8 cubic feet
- Loads: 8 ÷ 6 = 1.33
- Rounded up: 2 loads
Example 3 is a bed with a smaller barrow. Use the volume from Example 1 and a 3 cubic foot barrow.
- Loads: 33.33 ÷ 3 = 11.11
- Rounded up: 12 loads
The same job takes twice as many trips with a half-size barrow.
Loads per cubic yard
A truck delivers by the cubic yard, which is 27 cubic feet. At 6 cubic feet per load:
| Delivered | Cubic feet | Loads |
|---|---|---|
| 0.5 yd | 13.5 | 3 |
| 1 yd | 27 | 5 |
| 2 yd | 54 | 9 |
| 3 yd | 81 | 14 |
| 5 yd | 135 | 23 |
| 10 yd | 270 | 45 |
One yard is 4.5 loads, so the calculator shows 5. Two yards are exactly 9. Use these numbers to decide whether to ask for the pile near the work.
Heavy loads and light loads
The 6 cubic feet is a volume and not a weight. A full barrow of mulch is easy, and a full barrow of wet soil or gravel is not.
Using the weights on this site, topsoil at 1.1 tons per cubic yard works out to about 81 lb per cubic foot, so a full 6 cubic foot barrow is about 490 lb. Gravel at 1.4 tons per yard is about 104 lb per cubic foot, or roughly 620 lb for a full barrow. Few people can push that, and a barrow has a load rating.
For dense material, fill the barrow part way. Count the extra loads. If the calculator says 6 and you carry two-thirds loads, you need about 9.
How to measure
- Multiply the length and width of the area in feet. Break odd shapes into rectangles.
- Measure the depth in inches after you clear the area.
- For a trench, enter the length as the trench length, the width as its width, and the depth in inches.
- For material in a pile, estimate the volume. A pile of 2 cubic yards holds 54 cubic feet.
- Measure the distance from the pile to the bed. Long hauls change the time.
Planning the day
The load count tells you the number of trips. Time yourself on the first two trips, then multiply. If a round trip takes 3 minutes, 45 loads from a 10 yard pile is 135 minutes, and the time grows with every extra step. Plan breaks, because pushing loaded barrows is hard work, and consider a second person or a hired helper.
Place the delivery as close to the work as you can. Put a tarp under the pile and keep it clear of drains and the street.
Common mistakes
- Using a barrow’s size from the box, not the real working capacity. A heaped load spills.
- Not rounding up.
- Forgetting the weight. A barrow that fits 6 cubic feet of mulch cannot carry the same of gravel.
- Ordering a delivery that is blocked from the work site by a fence or steps.
- Leaving out the settling of mulch, compost or soil.

Frequently asked questions
How many cubic feet does a standard wheelbarrow hold?
This calculator uses 6 cubic feet per load, the size of a standard contractor wheelbarrow filled level to the tray. Homeowner barrows often hold 3 to 4 cubic feet. Check the capacity stamped on yours, and divide your volume by that number instead.
What if I only have a smaller, homeowner-size wheelbarrow?
Do the division by hand. Take the cubic feet from the calculation and divide by your barrow's size. A 33.3 cubic foot job is 6 loads at 6 cu ft, but 12 loads at 3 cu ft. Multiply the loads by the time each round trip takes to plan the day.
Why does this calculator round the load count up?
Because the last partial load still has to be hauled. 5.56 loads means 5 full barrows and a 6th partly full, so it shows 6. Rounding down would leave you with a pile of material and no plan for it.
Is it faster to use a wheelbarrow or just order bulk delivery?
Delivery brings the material to your driveway or a chosen spot, and a wheelbarrow moves it from there to the bed. Even with a delivery you still need the barrow unless the truck can reach the site. Use the load count to see how long the job takes.
Does this account for material that compacts or settles after spreading?
No. The count is for the volume you enter, as loose material. Mulch and compost settle, soil compacts when wet, and gravel drops when tamped. Add the extra to your depth, or plan an additional load or two.
