Pea gravel coverage calculator guide
Use area, depth, density, and bag size to compare pea gravel orders.
How to estimate pea gravel volume, weight, and bag count for paths, borders, and decorative landscaping.
Choose a realistic depth
Pea gravel quantity depends heavily on the finished depth. Decorative borders and paths can need different depths.
- Measure the finished area after edging is planned.
- Choose depth based on use, not only appearance.
- Use the pea gravel preset as a starting density estimate.
Compare bag and bulk options
Small bags are simple for small areas, while bulk bags or loose loads can make more sense for larger projects.
- Enter the actual bag size from the supplier.
- Compare kg and tonnes against bulk-bag listings.
- Check delivery access before choosing a loose load.
Pea gravel planning examples
| Project | Input to check | Why it matters |
|---|---|---|
| Border | Depth and edging | Prevents gravel spilling into planting. |
| Path | Foot traffic and base | Affects depth and preparation. |
| Driveway top layer | Sub-base and load | Needs more than a decorative estimate. |
This is an estimate. Site conditions, compaction, and aggregate type can change the final quantity.
Worked examples
5 x 3 m driveway A starting estimate for a 5 x 3 m area at 5 cm finished depth. 10 x 1 m path A starting estimate for a 10 x 1 m path at 4 cm finished depth. 4 x 4 m area A starting estimate for a 4 x 4 m area at 5 cm finished depth. 6 x 0.5 m border A starting estimate for a 6 x 0.5 m border at 4 cm finished depth.
