How to Calculate Chain Link Fence Materials
Chain link fences have several components: mesh fabric, line posts, terminal posts, top rail, ties, caps, and tension hardware.
- Mesh rolls: fence length ÷ 50, rounded up
- Terminal posts: corners + ends + (gates × 2)
- Line posts: every 10 ft between terminal posts
- Top rail: fence length ÷ 10.5, rounded up
- Ties: 1 per ft of rail + 3 per line post
- Tension bars: 1 per terminal post
- Tension bands: 1 per ft of fence height per terminal post
Tips & Considerations
- Double-check your total fence length before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both mesh rolls and line posts — they work together to give you the full picture.

Frequently Asked Questions
How much chain link mesh do I need?
Mesh comes in 50 ft rolls. Divide fence length by 50 and round up. For 150 ft: 3 rolls. Add an extra partial roll for corners and gates.
How far apart are chain link posts?
Line posts every 10 ft. Terminal posts (larger) at every corner, end of run, and each side of gates.
Terminal posts vs line posts?
Terminal posts are 2-7/8" diameter at corners, ends, and gates. Line posts are 1-5/8" diameter at 10 ft intervals between terminal posts.
How much top rail?
Top rail comes in 10.5 ft sleevable lengths. Divide fence length by 10.5 and round up.
How many fence ties?
1 tie per foot of rail plus 3 ties per line post. Buy in bags of 100.
Do I need tension wire?
Recommended along the bottom to prevent mesh from being pushed up. Plan for full fence length plus 10%.
