Why Use a Landscape Edging Calculator?
Underestimating garden edging section counts leads to uncompleted flower bed borders, while miscalculating anchoring stakes causes sagging or elevated edges over time.
- Calculate Exact Section & Roll Quantities: Instantly convert garden bed perimeters into 4 ft strips, 10 ft commercial lengths, or 20 ft flexible rolls.
- Determine Ground Anchoring Stakes: Compute required metal or plastic anchoring spikes based on recommended 18” to 36” stake spacing.
- Include Overlap & Trimming Waste: Factor in 10% extra material for corner cuts, curved bends, and joint overlap.
- Budget Total Project Costs: Estimate combined material costs for edging rolls and anchoring stake packs before going to the home center.
Landscape Edging Calculation Formulas
\[\text{Gross Linear Feet} = \text{Garden Perimeter (ft)} \times \left(1 + \frac{\text{Waste \%}}{100}\right)\] \[\text{Edging Sections / Rolls} = \left\lceil \frac{\text{Gross Linear Feet}}{\text{Section Length (ft)}} \right\rceil\] \[\text{Total Stakes Needed} = \left\lceil \frac{\text{Gross Linear Feet} \times 12}{\text{Stake Spacing (in)}} \right\rceil + \text{Sections Count}\] \[\text{Edging Material Cost} = \text{Sections Count} \times \text{Price per Section}\] \[\text{Stakes Cost} = \text{Total Stakes} \times \text{Price per Stake}\] \[\text{Total Project Cost} = \text{Edging Material Cost} + \text{Stakes Cost}\]Real-World Landscape Edging Material Comparison Table
The table below shows total material requirements, section counts, anchoring stakes, and total costs across typical garden bed perimeter sizes, assuming 10% waste allowance and 24-inch stake spacing.

Step-by-Step Guide: How to Measure & Install Landscape Edging
- Outline Your Garden Bed: Lay out a garden hose or rope along the intended bed boundary to trace natural curves or crisp lines.
- Measure Total Perimeter: Measure the hose length using a tape measure to get the exact linear footage of edging required.
- Trench the Border: Dig a narrow trench 2 to 4 inches deep along the perimeter using a flat lawn edging shovel.
- Unroll or Lay Strips: Uncoil flexible plastic edging in the sun to relax the material before dropping it into the trench.
- Secure with Stakes: Drive anchoring spikes angled at 45 degrees into the ground through designated stake tabs or slots every 24 inches.
- Backfill & Mulch: Tamp soil tightly against both sides of the edging and top off garden beds with mulch, river rock, or soil.
Frequently Asked Questions
How many landscape stakes do I need per foot of edging?
For standard plastic coil edging, place an anchoring stake every 2 to 3 feet (24 to 36 inches). For curved borders or loose soil, place stakes every 1.5 to 2 feet (18 to 24 inches) plus an extra stake at all joints.
How much overlap should I account for when connecting edging?
Allow 4 to 6 inches of overlap at every joint or connection point. Adding a 10% waste margin in the calculator comfortably covers corner cuts and overlapping seams.
Should I choose 4 ft rigid strips or 20 ft flexible rolls?
Flexible 20 ft rolls are best for sweeping, curved flower beds and continuous borders with minimal seams. Rigid 4 ft or 10 ft metal/plastic strips work best for crisp, straight lawn edges and formal rectangular designs.
How deep should landscape edging be installed?
Edging should be buried approximately 2 to 4 inches into the soil so that 0.5 to 1 inch remains above the grass soil level. This prevents grass roots from spreading while allowing lawn mowers to pass over safely.
What is the average cost of garden landscape edging per foot?
Standard black plastic coil edging costs $0.60 to $1.20 per linear foot. Metal or aluminum edging costs $2.50 to $4.50 per foot, and stone or concrete pavers range from $3.50 to $8.00+ per foot.
Can I install garden edging on slope inclines?
Yes, flexible plastic and bendable aluminum edging conform well to slope contours. Increase stake frequency on steep inclines to prevent soil movement and washouts.
