Frequently Asked Questions
How much soil do I need for a raised bed?
Multiply the bed's length, width, and depth (converted to the same units) to get cubic feet, then convert to cubic yards or bags as needed.
Should I fill the bed 100% full?
Most gardeners fill 90-95% to leave room for mulch and settling, which is why this calculator includes a fill percentage slider.
How many bags of soil equal a cubic yard?
A cubic yard is 27 cubic feet, so with 1.5 cubic ft bags you'd need 18 bags per cubic yard.
