Raised garden bed planner
Fill raised beds without buying too much soil.
Enter the inside dimensions and fill depth to estimate soil volume, bag count, weight, and bulk quantity.
What are you filling?
More shapes
Use the inside dimensions and the actual depth you plan to fill with soil.
Diagram not to scaleEnter your measurements
Add a waste allowance
The suggested allowance reflects the selected bed shape.
Compare purchase options
Confirm delivery area, minimum order, moisture, and actual load weight with the supplier.
Add local price to estimate cost
How this estimate is calculated
This is a planning estimate. Soil weight changes with moisture and composition. Confirm product volume, load limits, site conditions, and delivery requirements before ordering.
A reliable estimate in four steps
Measure once. See the math. Buy with confidence.
- 1Choose the project shape
Select the geometry that best matches the area you plan to fill.
- 2Enter measured dimensions
Use US or metric units and adjust individual fields when needed.
- 3Review the waste allowance
Use the project suggestion or enter a value that matches site conditions.
- 4Compare purchase options
Use the recommended bag count or bulk quote quantity as a starting point.
Project calculators
Start with a focused topsoil estimate.
Measure the area and average fill depth, then calculate bulk yards and an approximate delivered weight.
Soil Volume CalculatorCalculate soil volume from dimensions and see cubic feet, cubic yards, cubic meters, liters, bags, and weight together.
Garden Soil CalculatorUse measured dimensions and a practical depth to compare bagged garden soil with bulk blended soil.
Topsoil Coverage CalculatorEnter a known area or use the depth presets to convert square feet into cubic yards and bags.
Topsoil Cost CalculatorCalculate what the project needs, then add local bag or per-yard pricing for a clear material estimate.
Planning guidance
Common topsoil estimate questions.
How much soil do I need for a 4×8 raised bed?
A 4×8 bed filled 12 inches deep needs about 32 cubic feet, or 1.19 cubic yards, before adding a settling allowance.
Should a raised bed be filled completely with topsoil?
Usually no. A blended raised-bed mix with topsoil, compost, and aeration material drains better than dense topsoil alone. Confirm the mix with your supplier.
How much extra topsoil should I order?
A 5–10% allowance is a practical starting point for settling, uneven grades, and measurement error. Use 10–15% for irregular areas or uncertain depths.
Should I buy topsoil in bags or in bulk?
Bags are convenient for small repairs and a few planters. Around half a cubic yard, compare prices. For one cubic yard or more, bulk delivery is usually easier and more economical.
