Chain Link Fence Calculator

How this calculator works

This calculator treats the fence as one straight run and spaces posts evenly, rounding the number of sections up so spacing does not exceed your entered maximum. A real layout with corners, gates, grade changes, or multiple runs needs a separate layout plan; those features may change how many terminal and line posts you need.

sections = ceil(fence length ÷ post spacing)
total posts = sections + 1, but not fewer than terminal posts entered
line posts = total posts − terminal posts
mesh rolls = ceil(fence length ÷ roll length)

Worked example

A straight 100 ft run with 8 ft maximum spacing has ceil(100 ÷ 8) = 13 sections and 14 posts. If 2 are terminal posts, that leaves 12 line posts. With 50 ft mesh rolls, plan on 2 rolls.

Check the materials for your fence system

Mesh roll length and post spacing are user-entered because chain-link products and installation requirements vary. The top-rail estimate is a simple linear-foot total and does not add cut waste, fittings, sleeves, or extra rail at gates. Verify post type, rail lengths, tension bars, bands, ties, and concrete against the chosen system’s instructions.

Confirm height and site conditions

Fence height, soil, wind exposure, slope, and local rules affect post selection and embedment. This tool estimates counts only; it does not size posts, foundations, or hardware. Check local requirements and the manufacturer’s instructions before ordering or installing.

Frequently asked questions

How many posts do I need for a chain-link fence?

For a straight run, divide its length by the maximum spacing, round the section count up, and add one post. Then distinguish line posts from the terminal posts required at ends, corners, and gates.

How far apart should chain-link fence posts be?

Spacing depends on fence height, system instructions, terrain, and local requirements. Enter the maximum spacing specified for your project rather than treating the default as a universal rule.

How many rolls of chain-link mesh should I buy?

Divide the total straight-run length by the usable length of one roll and round up. Check the actual roll length and allow for overlap, cuts, gates, and layout changes.

Does this calculator include gates and corners?

No. It estimates one straight run. Enter the total terminal-post count you plan to use, but separately account for gate openings, corners, changes in direction, and multiple runs.
