How to measure a curved bed
Lay a garden hose along the edge, mark where it starts and ends, then straighten it out and measure it. Choose "I measured the edge length" and enter that number. This works for any shape, including kidney beds and winding borders.
How the math works
For a rectangle, the edge is twice the length plus twice the width. For a circle, it's the diameter times 3.14. A 20 by 5 foot bed has 50 feet of edge, or about 53 feet with 5% extra, which is 3 rolls of 20 feet and 17 stakes.
Types of edging
| Type | Typical piece | Good for |
|---|---|---|
| Plastic or rubber roll | 20–60 ft roll | Curves, low cost |
| Steel or aluminum | 4–8 ft sections | Crisp, nearly invisible lines |
| Paver or brick | Individual units | Mowing strips, formal beds |
Common questions
How deep should edging go?
Bury most of the edging, leaving about half an inch above the soil. That's enough to stop grass and mulch from crossing over, while the mower wheel can roll along it.
How far apart should stakes be?
About every 3 feet for plastic rolls, and closer on tight curves. Metal edging usually comes with stakes or clips at set spacing.
