The recommended depth of topsoil for creating lawns from turf or seed is 100 to 150mm (4 to 6 inches), 150 to 200mm of soil depth is usually sufficient for most planting or general gardening. The depth of topsoil for growing vegetables will vary depending on what you plan to grow. Root vegetables such as potatoes and carrots will need 300 to 400mm, whereas vegetables such as salads, beans and courgettes will need a depth of 150 to 200mm.

**How much topsoil do you need per square foot**

To calculate how much topsoil you need, simply measure the dimensions of the area you wish to cover and multiply this by the depth required. Measuring in feet is simplest, as this will give you the volume of topsoil you need in cubic feet.

For example: A site has an area of 25 feet x 20 feet and needs a coverage at 6 inches (150mm) thick, then quantity of topsoil you will need = 25′ × 20′ × 6/12′ = 250 cubic feet.

A site has an area of 1 feet long x 1 feet wide and needs a coverage at 6 inches (150mm) thick, then quantity of topsoil you will need = 1′ × 1′ × 6/12′ = 0.5 cubic feet. Thus, you will need 0.5 cubic feet of topsoil per square foot at recommended depth of 6 inches thick.

A site has an area of 1 feet long x 1 feet wide and needs a coverage at 4 inches (100mm) thick, then quantity of topsoil you will need = 1′ × 1′ × 4/12′ = 0.33 cubic feet. Thus, you will need 0.33 cubic feet of topsoil per square foot at recommended depth of 4 inches thick.

Regarding this, **“how much topsoil do you need per square foot”,** You will need approximately **0.5 cubic feet** of topsoil per square foot at recommended depth of 6 inches thick, **0.33 cubic feet** of topsoil at 4 inches depth, and **1 cubic foot** of topsoil at 12 inches depth for your garden, lawn or growing vegetables, or planting.

**How much topsoil do i need**

To calculate how much topsoil you need, simply measure the dimensions of the area you wish to cover and multiply this by the depth required.

Length in feet × width in feet × depth in feet (inches divided by 12). Results will be divided by 27 (the amount of cubic feet in a yard). The final figure will be estimated amount of cubic yards of topsoil required.

● Calculate square footage = Length in feet × width in feet, suppose a site an area of 10 feet long x 10 feet wide and needs a coverage at 6 inches (150mm), square footage = 10 × 10 = 100 square feet

● Depth in feet = depth in inches ÷ 12, so 6 inches in feet = 6 ÷12 = 0.5 feet.

● Volume of landfilled is equal as amount of topsoil needed, so, Volume calculation = square footage × depth, so, required amount of topsoil in cubic feet = 100 × 0.5 = 50 cubic feet

● Convert cubic feet in cubic yard = cubic feet ÷ 27, so value of 50 cubic feet in cubic yard = 50 ÷ 27 = 1.85 cubic yards.
