What types of garden edging are there?

Metal strip, plastic roll, brick, stone, log roll, and timber. Metal gives the cleanest line.

How do I install metal edging?

Push into soil along the border and secure with ground pegs every 30-50cm.

How deep should edging be?

At least 10cm in the ground to stay stable and prevent grass creeping under.

What types of lawn edging are available?

Metal strip edging, plastic roll edging, stone/brick edging, and timber edging are the main options. Metal gives the cleanest, most durable line.

How deep should lawn edging be installed?

Most edging should be buried 10-15cm deep to anchor it securely. The top should be flush with or slightly above the lawn surface to create a clean mowing edge.

Edging Calculator — Lawn & Border Edging

Calculate lawn or border edging quantities for straight and curved runs.

Total Length

Total run of lawn or border edge to be edged, in metres. Measure along the outside of any curves so you don't under-order.

Edging TypeProduct type sets the piece length automatically: metal & plastic strips 1m, a brick laid end-on 21.5cm, log roll 1.8m. Metal and plastic also add ground pegs.

How We Calculate This

Pieces = (Total Length ÷ effective piece length) × waste factor, rounded up. Metal and plastic strips are 1m, a brick laid end-on is 0.215m and log roll is 1.8m. The effective length subtracts any overlap you set. Metal and plastic edging are anchored with ground pegs (default 3 per 1m strip, roughly one every 30cm), so ground pegs = pieces × pegs per piece. Brick and log roll need no pegs.
