How many feet are in a roll of chain link fabric?
50 ft is standard for residential. A 100 ft run with one 4 ft gate needs two rolls plus waste, which is why the calculator works in rolls, not feet — you buy the roll, not the yard.
What's the difference between line posts and terminal posts?
Line posts (2⅜ in) hold the fabric along the run every 10 ft. Terminal posts (2⅞ in) sit at ends and corners and carry the tension hardware that stretches the fabric. The calculator counts them separately because they're different parts at different prices.
What gauge and mesh should I use?
Residential standard is 11½ gauge (now often 11 or 12 ga) with 2 in mesh; 9 gauge is the heavier commercial grade. The calculator offers three assemblies — residential 2×9, heavy residential 1½ in mesh, and commercial — with the cost multiplier for each.
Why does chain link need tension bars and bands?
The fabric is stretched onto tension bars at every terminal post and held with bands (roughly one band per foot of height plus one). Without tension hardware, the fabric sags between posts. It's the most commonly forgotten line on a chain link takeoff.
How far apart are chain link line posts?
10 ft on center for standard residential; some shops go to 8 ft for 4 ft fabric or slatted fence. Line posts are cheap relative to the fabric, so a missed spacing change matters less than missed terminals.
