The standard allowance most suppliers and estimating guides assume for ordinary work.
The length of the paved area.
Use the same dimensions as the Paver Calculator.
The width of the paved area.
Measure perpendicular to the length.
The length plastic or metal paver edging is sold in.
8 ft is the most common stock length in North America for both plastic and metal paver restraint edging; 2.4 m is the equivalent stock length in metric markets.
Extra edging for cut ends at corners and the offcut left at the end of each run.
Straight edging round a square patio loses little, because the offcut from one side starts the next. Curves need relief cuts, and every return or stop end leaves a short piece that fits nowhere, so a path with bends or an L-shaped patio wants more than ten.

How this was calculated
Formula source(s)
- Edging follows the full perimeter of the paved area: perimeter = 2 x (length + width); section count = perimeter / stock length, rounded up with a waste allowance — stock lengths are 8 ft and 10 ft in North America and 2.4 m and 3 m in metric markets
Inputs used
- Paved Area Length
- 19.5 ft
- Paved Area Width
- 13 ft
- Stock Edging Length
- 8 ft
- Cutting Allowance (%)
- 10
Intermediate steps
- Perimeter (with waste)
- 71.5 linear ft
What this calculation does not cover
- The perimeter is 2 x (length + width), so the count assumes a rectangle restrained on all four sides. It does not subtract a side that butts a house wall, an existing kerb or a step, and it does not add the extra run of an L-shape, a bay, a radius or a stop end.
- The cutting allowance is one percentage of the perimeter and does not rise by itself with how much cutting the job involves. Curves, returns and stop ends leave more unusable offcuts than a straight rectangular run, so set it higher for those; a section damaged on site is not in it at any setting.
- Only the edging sections are counted. Spikes, connectors and corner pieces are not, and the menu carries two stock lengths only, so coiled flexible edging sold by the roll, or sections of any other length, will not match this count.
- This is a quantity take-off, not a check that the restraint suits the loading. The count is the same for plastic, metal or any other spiked edging, and it does not judge whether spiked edging is enough for a driveway, a crossover, or any edge where wheels track close to the perimeter, where a concrete-haunched kerb or soldier course is the usual restraint.
- The count assumes there is compacted base past the last course for the spikes to bear on. That extra base sits outside the paved footprint you enter here and is not part of this calculation.

Tools and safety for this job
To lay the edge restraint. Generic types, no brands, no prices.
Protection this work requires
- Cutting or grinding concrete, masonry, screed, tile or fibre-cement board releases respirable silica: cut wet or extract at the tool, and wear a P2/N95 respirator at minimum — a nuisance dust mask does not filter it.
- Wet cement and lime burn skin and eyes painlessly until the damage is done: waterproof gloves to EN 374, safety glasses whenever the mix can splash, and never kneel in wet mix in permeable trousers.
- Saws, grinders and breakers run above 85 dB, where hearing damage accumulates and does not recover: defenders or plugs for every cut, not just the long ones.
- Breakers and grinders cause permanent nerve damage: limit continuous trigger time, keep hands warm, and stop if fingers tingle or blanch.
- Boards, blocks and bagged material cause most lasting back injuries on small sites: two people or a lifter for full sheets, and never a bag on one shoulder up a ladder.
