What would you like to do next?
Estimate raised-bed fill from measured dimensions
Enter bed length and width in feet, fill depth in inches, a settling allowance and the volume printed on a bag. The calculator shows base cubic feet, adjusted cubic feet, cubic yards, liters and the number of whole bags. This makes it possible to compare a bulk-delivery quote with bagged products using the same bed dimensions.
Subtract volume that is already occupied
Existing soil, interior structures, logs, paths and unfilled headspace reduce the amount required. Product volume and settling vary, so keep a small project-specific margin and confirm delivery minimums before ordering.
Frequently asked questions
Does the calculator round bags up?
Yes. The bag result is rounded up to a whole bag.
How are liters converted?
Cubic feet are converted using approximately 28.3168 liters per cubic foot.
Should I include existing soil?
No. Reduce the fill depth or subtract occupied volume before ordering.
