Fence Calculators
Posts, rails, pickets and gates for a full fence run. 6 free calculators.
A fence estimate depends on post spacing as much as total length - change the spacing and every other count (rails, pickets, concrete) changes with it - which is where most simple length-only calculators fall short.
These calculators start from your fence length and chosen post spacing, then work out posts, rails, pickets, gates and the post-hole concrete needed to set them, as one connected estimate.
