What Omni includes in fence material takeoff
The fetched Omni fence material page covers both wood and vinyl-style fence planning by focusing on the baseline pieces: posts, sections, rails, pickets, and concrete for the post footings.
Equations behind the source tool
Number of posts = Fence length / Post spacing + 1
Number of sections = Number of posts - 1
Post length = 1.5 x Fence height
Number of rails = Rails per section x Number of sections
Number of pickets = Fence length / (Picket width + Picket spacing)
10% spare rule from Omni
Omni recommends buying about 10% more fencing materials than the exact calculation to cover mistakes, cutoffs, or future repairs. This version shows both the calculated quantity and the 10% spare recommendation.
