Turn a bed perimeter into a practical edging purchase plan with openings, extra allowance and whole-piece rounding.
Change the defaults to match your project and the product you plan to buy.
Project result
See gross perimeter, opening deduction, extra-adjusted edging run, whole pieces and purchased surplus.
Planning estimate only. Verify product coverage, package size, supplier specifications and project requirements before purchasing.
Methodology
2 × (length + width)
Rectangular bed model.
gross perimeter − openings
Only subtract truly unedged sections.
net run × (1 + extra %)
Allowance for cuts/curves.
ceil(target ÷ piece length)
Whole-piece rounding.
Measure the actual path of the edging. For rectangular beds, length and width provide a quick perimeter, but curved or free-form edges are better measured with a flexible tape, string or measuring wheel along the intended line. Subtract only openings where no edging will be installed and measure transitions separately.
Enter the real stock length for the edging system and use an allowance that reflects curves, joints and cutting. The result rounds to whole pieces and reports surplus length, but connectors, stakes, corners and manufacturer-specific fittings may add separate quantities. Flexible roll edging may be better planned with its exact roll length.
Reference
| Planning item | Starting point | Verify / adjust |
|---|---|---|
| Gross perimeter | 2(L + W) | Rectangle model. |
| Openings | Subtract unedged runs | Do not subtract planted sections. |
| Curves | Measure actual path | Perimeter formula may be inaccurate. |
| Accessories | System-specific | Stakes/connectors are separate. |
Questions
Measure along the intended curve with a flexible tape, string or measuring wheel instead of relying on rectangle dimensions.
No. Those quantities depend on the edging system.
Yes if you enter the roll or stock length as the piece length, then confirm how many connectors or stakes are required separately.
