Topsoil Calculator - How Much Topsoil Do I Need?

Our Topsoil calculator allows you to precisely find the right amount of topsoil for your project. This ensures you get the correct coverage and depth, while minimising waste and saving you money.

How much topsoil do I need is one of the most commonly asked questions by gardeners looking to buy topsoil. Be sure to know exactly the correct quantity for your project or you could find yourself spending more than is needed, and with a pile of topsoil you don’t need! Alternatively you could find your garden project hampered by the need for a second, costly topsoil delivery. Calculate topsoil below to find the ideal quantity for your needs.

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).  

Try using our Topsoil Calculator below to work out how much topsoil you need.

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.

 

Topsoil bag coverage: How much do you need?

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 do I calculate how much gravel I need?

Our topsoil calculator doesn’t just have to be used for topsoil! Many gardening projects require a measuring tool to establish the volume of materials needed- gravel, sand and wood chippings among them. 10mm gravel for driveways should be measured to 5cm depth, while for other areas 3-4cm should be sufficient. For 20mm gravel 4-5cm would be better, with 6cm for drives. By working to these depths and measuring the area you intend to cover, our calculator can reliably calculate the precise volume of gravel which you need.

 

 

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!
