The leftover-gap problem
If you start at one end of a border and place a stake every 18 inches, the last gap rarely comes out to exactly 18 inches. You end up with a short gap at the finish, which looks uneven and can leave edging weakly supported. The better approach is to pick a whole number of gaps close to your target and divide the length evenly. That is what this calculator does: it rounds the number of gaps to the nearest whole number, then shows the actual spacing that fits the length exactly.
Open runs versus closed loops
An open run, like a straight fence line or the edge of a driveway, has a stake at both the start and the end, so it needs one more stake than the number of gaps. A closed loop, like edging all the way around a tree ring or an island bed, ends where it started, so the first stake also serves as the last and the count equals the number of gaps. Choosing the wrong layout is the most common counting mistake, which is why the calculator asks for it.
Choosing a spacing
The presets cover common starting points: 12 or 18 inches for landscape edging and 3 feet for a light border fence. The right interval depends on the product, so check the edging or fencing manufacturer’s instructions, and space stakes closer on curves, slopes, or soft soil where the material needs more support. You can enter spacing in inches or feet; the calculator converts inches to feet internally and shows the result back in the unit you chose.
Getting the length
For a straight run, measure end to end. For a bed, the perimeter is the length you want; the lawn square footage calculator reports perimeter for rectangles, circles, triangles, and irregular shapes. The same even-spacing logic is used for fixtures in the landscape lighting calculator, so you can lay out stakes and lights along the same edge.
How to use the stake spacing calculator
- Measure the total length of the run, or the perimeter of the bed, in feet.
- Enter your target spacing and choose inches or feet.
- Choose open run (start to end) or closed loop (around a bed).
- Read the stake count and the adjusted spacing.
- Mark the first stake, then measure each interval from that starting point using the adjusted spacing.
