Landscape Edging Calculator
Estimate the linear feet of landscape edging and number of sections needed to border beds, paths, and lawns.
Landscape Edging Calculator (Linear Feet & Pieces) Guide
The landscape edging calculator works out how much edging to buy to border a bed, path, or lawn. Choose a straight run, rectangle, or circle, and it calculates the perimeter in linear feet, adds a waste allowance for cuts and corners, and tells you how many edging sections and stakes to order.
How to Measure Edging
Edging is sold by length, so you need the perimeter. For a straight border it's simply the length; for a rectangular bed it's 2 × (length + width); for a circular bed it's π × diameter (about 3.14 × the width across). Divide the total by the length of one edging section, add 10% for cuts and corners, and round up.
Choosing Edging Material
Steel and aluminum edging give the cleanest, longest-lasting lines; plastic is cheaper and easier to curve; and paver or stone edging doubles as a mowing strip. Pair a crisp edge with the stone or rock inside the bed using our landscape stone calculator.
Frequently Asked Questions
How much landscape edging do I need?
Measure the perimeter of the bed: length for a straight run, 2 × (length + width) for a rectangle, or π × diameter for a circle. Add about 10% for cuts and corners. A 10 ft × 15 ft bed has a 50 ft perimeter, so plan for about 55 linear feet of edging.
How many stakes do I need for landscape edging?
Most edging needs about 3 stakes per section (roughly one every 2–3 feet), with extra at curves and joints. The calculator estimates stakes at three per section as a practical starting point.
How do I measure edging for a curved bed?
Lay a rope or hose along the curve, then measure the rope. For a roughly circular bed, you can also multiply the diameter by 3.14. Flexible plastic or aluminum edging follows curves best.
What is the best landscape edging?
Steel and aluminum edging last longest and hold the crispest line; plastic is the most budget-friendly and easiest to bend around curves; stone or paver edging is the most decorative and creates a mow-over strip. Choose based on the look, budget, and how tight your curves are.
