Straight fence run calculator
Estimate the bays and posts for one straight, uninterrupted run using your chosen post-centre spacing.
Assumptions and limits
- Bays = round up(run length ÷ post-centre spacing); posts = bays + 1. The final bay may need a different width. Nominal panel width is not automatically post-centre spacing.
- Exclude gates, changes of direction, shared corner posts, steps and separate runs; calculate each straight run separately. Check product dimensions and the site before ordering.
- This does not specify post size, footing, fence height, boundary ownership or planning suitability.
