How to Use This Calculator
- Measure the perimeter of your garden beds in linear feet.
- Select your edging material and piece length.
- Results show pieces needed and total linear feet. Use Professional tab for stakes, cost, and lifespan data.
Formula
Pieces Needed = CEILING(Perimeter × Waste Factor ÷ Piece Length)
Use a 1.05× waste factor for curved beds.
Example
Example: 60 lin ft of straight bed, 8 ft steel pieces → 60 ÷ 8 = 7.5 → 8 pieces needed (64 total lin ft purchased).
Frequently Asked Questions
- Walk the perimeter of all beds you want to edge and add the total linear footage. Add 5% extra for curved beds and cuts.
- Install edging 4–6 inches deep, with at least two-thirds of the edging height buried below grade. This prevents frost heaving and keeps the edging stable.
- Natural stone edging lasts 50+ years. Aluminum edging lasts 25+ years. Steel edging lasts 15–20 years with a rust-resistant coating. Plastic edging lasts only 5–10 years due to UV degradation.
- Steel and aluminum edging typically requires one stake every 2 feet. Plastic edging often comes with integrated stakes every 12–18 inches.
- Add 5–10% to your measured perimeter for curves. Flexible aluminum and plastic edgings handle curves well. Steel edging may require closer stake spacing on tight curves.
