Garden bed soil planner
Plan garden soil by bed size and fill depth.
Use measured dimensions and a practical depth to compare bagged garden soil with bulk blended soil.
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.

Planning guidance
Common topsoil estimate questions.
How deep should garden soil be?
Many vegetable beds use 8–12 inches of workable soil. New in-ground beds may need less imported soil when the native soil is amended rather than replaced.
Is garden soil the same as topsoil?
Not always. Garden soil is commonly a blend of topsoil, compost, and other amendments. Check the product label or supplier mix before ordering.
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.
