# Flagstone Calculator

This calculator adds up the square footage of your patio, walkway or wall.

Bring that number to Mid Valley Rock or call (916) 363-4239, and we will turn it into a quote by weight for the stone and thickness you choose.

Flagstone is sold by weight. Coverage per ton depends on the stone and its thickness, so bring or send this number and the yard converts square feet to tons for the stone you pick.

### Gravel, pebbles or a base layer

Depth in inches

Cubic yards for the area above 0 cu yd

Cubic yards = square feet × depth in inches ÷ 324. Valley Gold gravel comes in super sacks of about 3,000 lb; tell us the cubic yards and we will tell you how many sacks. For boulders, see [boulder sizes and weights](https://midvalleyrock.com/rock-talk/boulder-sizes-and-weights/).

Flagstone is sold by weight, but projects are measured in square feet. The first step is knowing your area. Enter the dimensions of each section of your project, and the calculator totals the square footage for you. How far that stone goes depends on the thickness and the shape of the pieces, so our staff will help you convert square feet into the right amount of stone.

## How to measure

- Measure each area with a tape measure, in feet.
- Break odd shapes into rectangles, circles and triangles, and enter each one.
- Note how wide you want the joints between stones.
- Read the total square footage the calculator gives you.
- Bring the number to the yard or call (916) 363-4239 for a quote.

## Notes

- Measurements are approximate estimates. Actuals may vary.
- Coverage varies with thickness and piece shape. Thicker stone weighs more per square foot, so the same weight covers less area.
- Add extra for cuts, trimming and waste, especially on curved or irregular layouts.
- Bring your measurements, a sketch and photos of the area when you visit the yard.
- Our staff will convert your square footage into a pallet and weight quote for the stone you choose. See [how much flagstone do I need](https://midvalleyrock.com/rock-talk/how-much-flagstone-do-i-need/).
