How much soil does a raised bed need?

Soil volume is bed length times width times fill depth, converted to cubic feet and bag counts. Fill in lifts and water each layer so the mix settles.

Which lumber is safe for growing food?

Untreated cedar, redwood, or naturally rot-resistant species are the common choices for edible beds. If you use another material, line the interior.

Are the material costs accurate for my area?

Costs are regional estimates only, indexed by ZIP against national material averages. Always confirm current prices with your supplier before buying — the numbers here are for planning and budgeting, not a quote.

Do I need to confirm my measurements first?

Yes. The calculator asks you to verify key dimensions before it will produce material, cut, or shopping lists, because a single mistyped dimension changes every quantity downstream.

How big is the bed?

4ft wide is the sweet spot — you can reach the middle from either side. 8ft long fits standard lumber with no cutting.
