How much soil for a 4x8 raised bed?
The 4×8 ft example at 12 in depth is 32 cu ft before waste. With 5% added, estimate 33.60 cu ft (1.24 cu yd), or 17 bags labeled 2 cu ft.

Before you order
- Confirm bag volume or bulk delivery increment.
- Confirm material type, access and delivery charge.

The starting yield is an example for this bag size. Replace it with the product label; bag weight alone does not determine yield.
- 2 cu ft bags33.6 cu ft with allowance ÷ 2 cu ft per bag; rounded up.
- 17bags
What this estimate assumes
- One foot is 12 inches and one cubic yard is 27 cubic feet. Waste is added before computing each supply alternative.
- Bulk delivery, 2 cu ft bags and 3 cu ft bags are alternatives. Bag labels must match the selected volume; bulk minimums and order increments are not assumed.
- Bag yield entered: 2 cu ft/bag. Whole bags provide 0.4 cu ft above the volume with allowance.
- Only the selected supply method is listed; alternatives are not added together.

How to check this list before buyingMeasure the space to fill
Use the internal bed dimensions and actual fill depth. Subtract space already occupied by soil or other materials before estimating additional fill.
The volume calculation does not choose a soil blend or predict settling. Confirm the product and any additional allowance with your supplier. Bulk volume and bag counts are alternative ways to supply the same planned volume.
