Landscape Edging, Stake and Connector Calculator
Estimate edging length, stock pieces, connectors, stakes, waste, and editable cost for straight and curved runs.
How to use the landscape edging calculator
- Measure the actual project. Break irregular work into separate sections and record finished dimensions consistently.
- Enter the core measurements. The quick view focuses on project geometry; add or subtract sections where the calculator supports multiple areas.
- Review purchasing assumptions. Open Advanced inputs to replace example prices, waste, coverage, density, pack size, minimum order, or delivery assumptions with current project information.
- Calculate and verify. Review the formula, limitations, whole-unit rounding, product instructions, and supplier requirements before purchasing.
Key inputs covered: Edging piece length, Maximum stake spacing, Cut and waste allowance, Edging-piece example price, Connector example price, Stake example price, Run shape, Measured run length, Arc radius, Arc angle, and additional project-specific assumptions.
Result coverage: The landscape edging calculator reports 6 separate quantities so the primary estimate and its supporting purchase or planning values can be checked together.
How the estimate works
Straight lengths and circular arc lengths are summed; waste is applied before stock pieces round up, while connectors and stakes follow run breaks and maximum spacing.
A 90° arc with an 8 ft radius is one quarter of a 16π ft circumference, or about 12.57 ft.
Assumptions, rounding, and limitations
Dimensions are treated as finished measurements. Only deductions and allowances entered above are included. Decimal measurements display to two places; purchase quantities round up when a whole container or piece is required.
- Measured curves can be entered directly; arc mode assumes a true circular arc.
- Corners, closed loops, grade changes, soil, and product fastening rules may require extra fittings or stakes.
- Confirm overlap, connector, and minimum-bend requirements for the selected edging.

Editorial process
BuildPlanCalc publishes the formula, editable assumptions, limitations, and supporting references so the estimate can be checked rather than treated as a black box. See the calculation and review methodology, or report a correction.
Frequently asked questions
Are the results exact?
No. Results are planning estimates based on the dimensions and assumptions entered. Confirm product coverage, site conditions, and ordering rules with the supplier.
