Fence Calculator: Estimate Your Project with Our Free Tool

Use this fence calculator to determine the materials and measurements needed to build your fence.

Fence Post Calculator

This calculator helps you determine the number of posts you need for your fence based on the total length of the fence and the spacing between the fence posts.

How to Use the Calculator

  1. Enter the total length of the fence in meters into the first input field.
  2. Enter the desired spacing between posts in meters into the second input field.
  3. Click the “Calculate” button to see the result.

How It Calculates

The calculator divides the total length of the fence by the post spacing to determine the number of intervals between posts. It then adds one to account for the last post at the end of the fence. This total is rounded up to ensure you have enough posts, as you can’t have a fraction of a post.


Please note that this calculator assumes a straight fence line and uniform spacing between posts. It does not account for changes in terrain, gates, or additional reinforcement that might be necessary for corners or significant changes in fence direction.
