How much landscape edging do I need?
Measure every bed edge, lawn border, paver edge, or stone edge in linear feet. Divide by the stock length and round up.
Curves and corners matter
Curved beds, tight corners, short returns, and transitions can use more pieces or stakes than a straight-line measurement suggests.
Keep accessories separate
Stakes, spikes, connectors, corner pieces, caps, adhesive, excavation, and base prep may be separate from the visible edging material.
Gravel project example estimates
Examples are before waste and before any tonnage conversion. Supplier density and compaction can change the order.
| Project example | Area and depth | Cubic yards |
|---|---|---|
| Path | 150 sq ft at 2 in | 0.93 cu yd |
| Decorative rock bed | 250 sq ft at 3 in | 2.31 cu yd |
| Small parking pad | 300 sq ft at 4 in | 3.70 cu yd |
| Driveway strip | 480 sq ft at 4 in | 5.93 cu yd |
| Deep base layer | 600 sq ft at 6 in | 11.11 cu yd |
Gravel coverage by depth
Coverage assumes 1 cubic yard, which is 27 cubic feet. Waste, compaction, settling, and irregular grade are not included.
| Depth | Coverage from 1 cu yd | Coverage from 2 cu yd |
|---|---|---|
| 1 in | 324 sq ft | 648 sq ft |
| 2 in | 162 sq ft | 324 sq ft |
| 3 in | 108 sq ft | 216 sq ft |
| 4 in | 81 sq ft | 162 sq ft |
| 6 in | 54 sq ft | 108 sq ft |
| 12 in | 27 sq ft | 54 sq ft |
Before you calculate
- Measure each bed edge, paver edge, or lawn border in linear feet.
- Separate straight runs, curves, corners, and material types when they use different pieces.
- Use the stock length and connector system for the selected edging.
Common mistakes
- Forgetting stakes, connectors, corner pieces, and end caps.
- Measuring only straight runs when curved beds need extra cuts.
- Using decorative edging where paver edge restraint is required.
Formula
pieces = ceil((length * (1 + wastePercent / 100)) / pieceLength)
Assumptions
- Measure separate runs when material, curve, stock length, or spacing changes.
- Corners, overlaps, curves, cuts, and damaged pieces can increase final quantity.
- This estimates quantity only, not layout suitability.
Example
Estimated gabion border stone needed: 22 linear sections
How to calculate gabion border stone linear sections
- Measure the total run length in feet.
- Enter the usable length per piece, roll, board, strip, or section.
- Add waste for cuts, overlaps, corners, and damaged pieces.
- Divide adjusted length by usable piece length and round up to whole units.
- Keep fasteners, connectors, corners, end caps, and layout hardware as separate checks.
Before you buy materials
- Round up to full pieces and verify stake spacing.
- Keep excavation, base prep, spikes, connectors, and labor separate from the main edging count.
FAQ
What is the example gabion border stone linear sections result?
Use total run length, usable unit length, and waste, then calculate the planning result. In the default example, the result is 22 linear sections.
How do I calculate landscape edging?
Use pieces = ceil((linear feet x (1 + waste percent / 100)) / stock piece length).
Should I add waste for edging?
Yes. Curves, cuts, corners, damaged pieces, and layout changes usually need a small buffer.
Does this include stakes or spikes?
No. It estimates main edging pieces or cost. Stakes, spikes, connectors, and corners may be separate.
Can I use one edging type everywhere?
Not always. Paver restraints, metal edging, plastic edging, and stone edging serve different project details.
