About this calculator
Calculate how many cubic feet and bags of soil you need to fill one or more raised garden beds based on their dimensions.
Frequently Asked Questions
Should I fill the bed to the very top?
Most gardeners fill beds to about 1-2 inches below the top edge to prevent soil spilling out, so consider using a slightly reduced height in your calculation.
Is bulk soil cheaper than bags?
For beds requiring more than about 1 cubic yard of soil, buying in bulk from a landscape supplier is usually significantly cheaper than buying bagged soil.
Should I mix in compost?
Many raised bed mixes combine topsoil, compost, and aeration material like perlite; this calculator gives total volume, which you can then split by your preferred mix ratio.
