Work out how many fence posts and sections you need, based on total fence length and desired post spacing.
The calculator divides the fence length by the post spacing, rounds up to the nearest whole section, and adds one extra post on top of the sections (since each section needs a post at each end, shared with the neighboring section):
Standard post spacing varies by fence type: wood fences often have 2–2.5 m between posts, while heavier materials like wrought iron or masonry may require tighter spacing for adequate strength.
Because each section (panel) needs a post at each end, and neighboring sections share the post between them. For a straight fence with n sections, you therefore need n+1 posts — one extra at each outer edge.
2–2.5 meters is common for most wood fences, but always check the manufacturer's recommendation for your specific fence system, since spacing affects both stability and material use.
Yes, corners and direction changes usually require a dedicated post right at the bend point, in addition to the evenly spaced posts along each straight run of fence. This needs to be added on top of this calculator's base calculation.
