How much soil do I actually need for my garden bed?+
Multiply the bed's length by width by the desired soil depth to get volume, then convert to the units your supplier sells in (usually cubic feet or cubic yards, or liters/cubic meters). Most vegetable beds need 8-12 inches (20-30 cm) of depth for good root growth.
Why does the calculator ask for depth separately from area?+
Soil volume is a three-dimensional measurement, but most people only think in square footage. Depth varies by what you're growing: shallow greens need less than deep-rooted crops like tomatoes or carrots, so separating the two lets you adjust for your specific plants.
Should I round up the amount of soil I order?+
Yes, order 10-15% extra. Soil settles and compacts after watering and over the first season, and having a small surplus for topping off beds later is more convenient than running short mid-project.
Does this calculation account for existing soil in the bed?+
No, it calculates the total volume of the space you define. If you're filling a bed that already has soil, subtract the existing soil's depth from your target depth first, or measure only the empty space you need to fill.
What's the difference between cubic feet and cubic yards for ordering soil?+
Bagged soil is typically sold in cubic feet (a standard bag is about 1.5 cubic feet), while bulk delivery from a landscape supplier is priced by the cubic yard, which equals 27 cubic feet. For large beds, bulk is almost always cheaper per unit volume.
