Area: shape and size
Skip the drawingDrag a round corner to move it. The small hollow diamond on a side is its curve handle: drag it across the side to curve the side (it is not a corner). To add a corner (a new point), tap the side itself, then choose Add a point here. Tapping a corner or a side opens its actions. Drag empty space to move the view; pinch, or Ctrl and the mouse wheel, to zoom. The keys are listed under Keys.

Example: a pea gravel area
1 yd³ to order (0.62 yd³ exact)
- Volume in the area 16.67 ft³
- Cubic yards to order 0.62 yd³
- Cubic yards at the supplier's step 1 yd³
- Bags of the size above 34 × 0.5 ft³ bags
Your project
Enter a size to see your total.
Each product is rounded up once for the whole project, so the total can be less than the items bought alone added together. A line counted from a cut layout (sheets, boards or tiles laid out piece by piece) is counted for each item and added.

Worked example: a pea gravel area
Show the working
- Area 10 ft × 10 ft = 100 ft²
- Volume at the depth 100 ft² × 2 in = 16.67 ft³
- Add the waste allowance, once 16.666667 ft³ + 0 % waste = 16.67 ft³
- Cubic yards: divide by the cubic feet in a yard 16.666667 ft³ ÷ 27 ft³ in a yd³ = 0.62 yd³
- Round up once, to the supplier's yard step 0.62 yd³ = 1 yd³
Assumptions
The figures behind the example. Sourced figures link to their source below; a default is a starting value to check against your label or supplier.
| Assumption | Value | Details and changes |
|---|---|---|
| Landscape waste or overage | 0% | |
| Default No silent overage. Check your label or supplier. | ||
| Supplier's smallest yard step | 0.5 yd³ | |
| Default Suppliers sell bulk in steps. Check your label or supplier. | ||
| Supplier's smallest ton step | 1 ton | |
| Default Suppliers sell by the ton in steps. Check your label or supplier. | ||
| Stone bag size | 0.5 ft³ | |

Pea gravel for a square patch, by depth
Cubic yards and bags of pea gravel for a ten by ten foot area at four depths, with no waste allowance
| Depth | Cubic yards | Cubic yards at the supplier's step | Bags of 0.5 ft³ |
|---|---|---|---|
| 1 in | 0.31 yd³ | 0.5 yd³ | 17 bags |
| 2 in | 0.62 yd³ | 1 yd³ | 34 bags |
| 3 in | 0.93 yd³ | 1 yd³ | 50 bags |
| 4 in | 1.23 yd³ | 1.5 yd³ | 67 bags |
Each depth is worked out on its own. No weight appears because none is a sourced figure for pea gravel.
Questions
How many bags of pea gravel for a ten by ten area?
The table gives bags at four depths for that area at the bag size in the assumptions; the calculator does the same for your own sizes.
Why does the pea gravel calculator not give tons straight away?
No source gives a weight for pea gravel, so the weight is a field you fill in from your supplier or the label. Until you do, the calculator works in cubic yards and bags.
