Order enough soil for raised beds without guessing

'How much soil?' is a volume question with a bag-count answer — length × width × depth, then divide by the bag size.

The job

Raised beds eat soil. A 120×60×30cm bed is 216 litres — that's 11 of the standard 20-litre bags, per bed. Multiply wrong and you're either making a second trip or storing leftovers.

Dimensions in, bags out

Bed length, width and depth in centimetres, how many beds, and the bag size you're buying (10/20/25/40/50 litre presets). Fill percentage covers beds you're only part-filling — 60% soil over a base layer is normal for tall beds.

Litres are the currency — bag sizes and bulk soil both quote in them. The cubic-metre figure covers the bulk-delivery option.
Soil settles 10–20% in the first weeks — order at the top of your tolerance or plan a top-up.

Mixing in other material

Fill percentage is the knob: hugelkultur-style beds with a log base, or beds topped with compost, set it below 100. The answer then is 'soil on top', not total fill.
