How it's calculated (visible formula)
posts = ceil(length ÷ spacing) + 1; rolls = ceil(length × (1 + waste) ÷ roll length); wire = strands × length
- Net geometric measurement, no waste.
- Adjustable waste % for cuts and breakage.
- Purchase rounded up to sellable units (boxes, bags, buckets, boards).
How to calculate it, step by step
- Measure total length and count ends, corners and gates.
- Pick fabric height and post spacing (about 10 ft).
- Work out line posts and terminal posts with braces.
- Work out fabric rolls with a little waste.
- Add tension wire (2 or 3 strands) and tensioners.
Worked example: 100 ft × 5 ft, posts every 10 ft, 2 ends
- 100 ÷ 10 = 10 + 1 = 11 posts: 9 line + 2 terminal
- Fabric 105 ft → 3 rolls of 50 ft (2 of 25 m)
- 3 strands × 100 ft of wire
→ Fabric rolls, 11 posts, 4 braces and 6 tensioners.
Common mistakes
- Skipping braces at ends and corners.
- Stretching fabric before the post concrete has cured.
- Leaving out a middle wire on fences over 4 ft.
Pro tips
- Set terminal posts first and let concrete cure before stretching.
- Stretch the fabric from one end with a tension bar and come-along.
- Tie fabric to the top rail or wire every 12–24 in.
- Bury 8 in of fabric or add a bottom rail where dogs dig.

FAQs
- How long is a roll of chain link?
- 50 ft in the US; 25 m in Europe.
- How far apart are chain link posts?
- Up to 10 ft on center; closer on slopes.
- Top rail or tension wire?
- A top rail is stiffer; tension wire is cheaper. Bottom tension wire stops the mesh from lifting.
- What gauge chain link?
- 11½ ga residential; 9 ga for commercial or security.
- Galvanized or vinyl-coated?
- Vinyl-coated lasts longer and blends in better.
- How wide are chain link gates?
- Walk gates about 4 ft; drive gates 10–12 ft, often double.
