YOUR LITTLE WORKBENCH
Raised bed soil
Start with the example, then make it your own. Results update as you type.
How this is calculated
Volume = length × width × depth × bed count. Add your allowance, then round the bag count up.

Use internal measurements and the actual depth you want to fill. Existing soil and drainage layers reduce the required depth. This is a geometric volume, not a soil recipe or a weight estimate.
THE METHOD / 01
Know what goesinto your result.
Volume = length × width × depth × bed count. Add your allowance, then round the bag count up.
Keep the assumptions clear
Use internal measurements and the actual depth you want to fill. Existing soil and drainage layers reduce the required depth. This is a geometric volume, not a soil recipe or a weight estimate.
