How to calculate landscape edging
Example: three beds with 35 ft, 22 ft and 18 ft of border = 75 ft. With 5% extra that's 79 ft — four 20 ft rolls of plastic edging, or ten 8 ft steel pieces, plus about 27 stakes.
Measuring curves
Lay a garden hose or rope along the edge of the bed, mark where it ends, then straighten it and measure. Add each bed as its own border.
Which edging?
| Type | Pros | Cons |
|---|---|---|
| Plastic rolls | Cheap, easy curves | Can heave in frost, shorter life |
| Steel / aluminum | Crisp line, lasts decades | Costs more, needs stakes |
| Stone / pavers / brick | Classic look, mower strip | Most labor, needs a base |
Frequently asked questions
How do I measure for landscape edging?
Measure the length of every bed border — use a hose for curves — and add 5% for overlaps and cuts.
How many stakes do I need for edging?
Usually one every 3–4 ft for plastic and metal edging, plus one at each joint.
How many bricks for 10 ft of edging?
About 15 bricks laid end to end (8 in each).
How deep should landscape edging go?
Most edging should be buried so only about ½–1 inch shows above the soil.
