SettingsSettings for this calculationUS
The length of the edge you are lining, measured along it — curves included.
Lay a hose or a string along the line the edging will follow, then straighten it out and measure it, or walk a measuring wheel round it. Measuring the bed's length and width and adding them up under-counts a curved edge, because a curve is longer than the chord across it.
Whether the edge has two ends or closes on itself.
A closed loop has one more joint than an open run of the same pieces, where the last piece meets the first, and one fewer stake, because there is no second end to hold.
How the edging is sold. It changes what the answer counts, not the arithmetic.
Coiled plastic or rubber edging is joined end to end with a connector; straight metal or rigid lengths usually lap or pin into each other. Type the size in the next field and the overlap, if the system has one, in the one after.
The length of one coil or one straight piece, as printed on the pack.
Read it off the pack rather than assuming it: edging is sold in many sizes, from lengths of about 1 m (3 ft) to coils of 20 m (66 ft) or more. The default is a 20 ft (6.1 m) coil.
How much of each piece is lost where it laps the next one. Zero where the ends butt into a connector.
Coils joined with a connector sleeve butt end to end and lose nothing. Straight lengths that slot or lap into each other lose the overlap the maker's instructions give, at every joint, and that length is edging you buy but do not see.
The largest gap between stakes the edging's instructions allow.
Use the spacing on the pack, and close it up on tight curves and soft ground, where the edging wants to lift. The stakes are shared out evenly along the edge at or below this spacing.

How this was calculated
Formula source(s)
- Open run: pieces = (edge length - overlap) / (piece length - overlap), rounded up; closed loop: pieces = edge length / (piece length - overlap), rounded up. Joints = pieces - 1 open, pieces closed. Stakes = edge length / stake spacing, rounded up, plus one on an open run.

What this calculation does not cover
- The edge length is taken as measured and nothing is added to it. An edging that turns down into a path, wraps a corner post or tucks under a step uses more than the line on the ground, and a curve measured by pacing or across its chord is shorter than the edging that follows it.
- Stakes are spaced evenly along the whole edge and nothing extra is added at the joints. Where the instructions ask for a stake at every joint or either side of it, add the joint count, and close the spacing on tight curves and soft ground, which this page leaves to the figure you type.
- Every piece is taken as the same size and as usable to its very end. Offcuts are not carried from one bed to the next, so two beds worked separately can each leave a remainder that a single order would have used up, and a damaged or kinked coil end is not allowed for.
- This counts edging, connectors and stakes, not the digging. The trench depth, the edging's height above the lawn, any mowing strip laid beside it and the backfill are outside the count, and so is whether a light plastic edging is the right restraint at all where a path or a driveway runs next to it.
