Lawn & Garden
Turn garden-bed dimensions and fill depth into soil volume and practical bag or bulk quantities.
Change the defaults to match your project and the product you plan to buy.
Project result
Estimate bed volume, settling allowance, whole bags and bulk cubic yards.
Planning estimate only. Verify product coverage, package size, supplier specifications and project requirements before purchasing.
Choose the right tool
You are filling a rectangular garden bed and want soil volume, settling allowance and bag/bulk purchasing.
Use Topsoil for broad lawn/grading areas or Compost for top-dressing/amendment volume.
Methodology
length × width × depth
Depth is converted from inches.
base volume × settling %
Adds material for expected settling.
planned ft³ ÷ 27
Bulk-order reference.
ceiling(planned ft³ ÷ bag volume)
Rounds to whole bags.
Measure the inside bed length and width and the average depth you intend to fill. For tapered or irregular beds, divide them into sections and sum the volumes. Record the dimensions you used and recheck any section that is irregular, tapered or interrupted before relying on the final quantity.
Soil blends settle differently and bag volumes vary. Use the package volume or supplier bulk specification and avoid filling raised beds entirely with dense topsoil unless appropriate for the planting plan. Compare the calculated target with the exact package, coverage and availability offered by the supplier, then round only at the final purchase step.
Reference
| Planning item | Starting point | Verify / adjust |
|---|---|---|
| Settling | 5–15% planning range | Blend and moisture matter. |
| Bag size | Use label volume | Common sizes vary by product. |
| Bulk yard | 27 ft³ | Supplier delivery may have minimums. |
| Final order check | Use measured inputs | Confirm package size, supplier coverage and project conditions. |
Questions
It can be used for soil volume, but raised-bed blends often contain compost and other components.
Account for mulch, settling and the desired final soil line below the bed edge.
No. Enter only the depth of new material you plan to add.
