How to Use our Topsoil Calculator

  1. Measure Your Area: Determine the length and width of the area you need to cover with topsoil. If the area is not a perfect rectangle or square, break it down into manageable sections and measure those.

  2. Depth Requirement: Decide on the depth of the topsoil layer. This can vary depending on your project type. A good rule of thumb is 2-3 inches for new gardens and lawn repairs.

  3. Input Your Measurements: Enter the length, width, and desired depth of your area into our Topsoil Calculator.

  4. Get Your Results: With a single click, our calculator will tell you exactly how much topsoil you need, in cubic yards or tons.

Topsoil is most often sold by the metric tonne (1000kg), but the easiest way to calculate the quantity of topsoil required is by volume (cubic metres or litres).  

How do I Calculate Volume?

It is easiest to calculate volume in cubic metres or litres. To do this simply measure the length, width and depth of the area you need to fill with soil in metres and multiply the three figures together to get the volume in cubic metres.

Frequently-asked topsoil questions posed by new and experienced gardeners alike!

Getting value for money from your topsoil means understanding how much you need for a particular project. If you’re considering getting a topsoil bag for your garden, remember to plan your project before you buy, and consider the area, depth and density of topsoil you need.

How much topsoil do I need for my garden?

Using our topsoil calculator tool you can quickly & easily determine the measurements needed and the right amount for your budget. By providing the information you need, including the number of our bulk bags you need to fulfil your task, our guide helps makes buying the correct amount easy.

How much is a yard of topsoil?

1 square yard of our popular multipurpose topsoil, measured to the standard 35cm depth favoured by many gardeners for everyday root veg crops like potatoes and carrots, would require 450kg of topsoil. Our 1 tonne bags provide twice this, and are safe to store if ventilated and able to naturally dry. This means for one £70.80 bag you get 2 years’ supply!

How many cubic yards of topsoil do I need?

Most topsoil calculators, including ours, accept measurements in metres, yards or feet. Measure your borders or allotment accordingly to find two planes- if it’s a difficult shape break up the dimensions into smaller shapes to find the total area you’re seeking to cover.

How much does a cubic meter of soil weigh?

The weight of soil can vary enormously based on the volume of water it contains. One cubic metre of moderately damp soil (as freshly dug) soil weighs 1.3- 1.7 tonnes when dug, depending on how tightly packed it is. It should be noted that blended topsoil may be less dense and therefore closer to 900 litres or even 1 cubic metre to the tonne.

How many cubic feet are in a ton of soil?

1 tonne of packed topsoil measures roughly 24.7 cubic feet- that’s just under 3 feet along each plane- much heavier than it looks!
