Measuring guide

Measure before you buy

Gravel quantity starts with the depth you intend to place. A weight estimate needs the density of the specific material from your supplier.

01

Measure the space

Use feet for project length and width. Break irregular areas into rectangles and calculate each one.

02

Check the product

Use dimensions, packaging, and coverage from the specific material you plan to purchase.

03

Adjust the allowance

Change the starting 10% for the layout, cuts, spillage, and site conditions you expect.

The math

How this estimate is calculated

Length × width × depth in feet = cubic feet. Multiply by 1 + the extra allowance, then divide by 27 for cubic yards.

Quantities are for material planning. Confirm order units, coverage, and installation details with the product or supplier.
