How much garden 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.
Mulch bed example estimates
Examples are before waste. Add waste for uneven beds, curves, edge spillover, and settling.
| Project example | Area and depth | Cubic yards |
|---|---|---|
| Small border | 100 sq ft at 2 in | 0.62 cu yd |
| Medium bed refresh | 200 sq ft at 2 in | 1.23 cu yd |
| Medium new bed | 200 sq ft at 3 in | 1.85 cu yd |
| Large landscape bed | 500 sq ft at 3 in | 4.63 cu yd |
| Deep mulch area | 500 sq ft at 4 in | 6.17 cu yd |
Mulch 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
cubic yards = (area * (depth / 12) / 27) * (1 + wastePercent / 100)
Assumptions
- Depth is entered in inches.
- Measure separate zones when material, depth, slope, or compaction changes.
- Fabric, edging, drainage, delivery, grading, and labor are separate planning items.
Example
Estimated garden border mulch needed (cubic yards): 1.22 cubic yards
How to use this bark calculator
- Measure each bark or mulch bed in square feet, then split beds into separate estimates when refresh areas and new beds need different depths.
- Choose depth by purpose: use about 2 inches for a light refresh, 3 inches for a common new landscape bed, and deeper layers only where the project calls for them.
- Keep bark or mulch about 6 inches away from tree trunks and avoid piling material against plant stems, siding, or wood structures.
- Enter the bed area, finished depth in inches, and waste percentage, then review the cubic-yard result before ordering.
- Compare bags vs bulk by converting cubic yards to cubic feet; 1 cubic yard equals 27 cubic feet, so check bag volume, delivery minimums, and full-yard rounding before buying.
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 garden border mulch cubic-yard result?
Use area, installed depth, cubic-foot to cubic-yard conversion, and waste, then calculate the planning result. In the default example, the result is 1.22 cubic yards.
How do I calculate garden 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.
