Fence Mesh Calculator - Rolls, Posts, Top Rail & Hardware
Chain-link estimating starts with fence length, mesh roll length, height, and post spacing. The calculator estimates rolls, line posts, terminal posts, top rail, and tension hardware.
Percent added for cuts, waste, settlement, or field loss.
Cost uses rounded mesh roll count.

Chain-Link Mesh Parts Quick Reference
Materials for common chain-link fence layouts using 50 ft mesh rolls at 10 ft post spacing. Use this for the supplier conversation; the calculator handles your real values.
| Fence length | Mesh rolls (50 ft) | Line posts (10 ft OC) | Top rail (21 ft sticks) | Terminal posts (corners + gates) |
|---|---|---|---|---|
| 100 ft | 2 rolls | 9 posts | 5 sticks | 4 (2 corners, 2 ends) |
| 200 ft | 4 rolls | 19 posts | 10 sticks | 4-6 |
| 500 ft | 10 rolls | 49 posts | 24 sticks | 6-10 |
| 1000 ft (small lot perimeter) | 20 rolls | 99 posts | 48 sticks | 8-12 |
| 1 acre boundary (~835 ft) | 17 rolls | 83 posts | 40 sticks | 8 |
Add tension wire (1 roll of 7-gauge per 1000 ft), tension bands and brace bands (2-3 per terminal post), nuts/bolts, and post caps (1 per post). Concrete: 1-2 bags per line post hole, 2-3 bags per terminal post hole.
How Chain-Link Math Works
Chain-link is a four-part order: mesh + posts + top rail + hardware. The calculator computes:
- Mesh rolls = ceil(fence length / roll length). Standard rolls are 50 ft (residential) or 100 ft (commercial). Order one extra row if the fence wraps a corner over a length you cannot cut cleanly.
- Line posts = ceil(length / post spacing) - 1 + corners and gates. At 10 ft spacing, 100 ft of fence has 9 line posts in between plus the two end terminals.
- Top rail = ceil(length / 21 ft stick length). Top rail comes in 21 ft sticks with a swaged end - they slide together for a continuous rail.
- Tension wire = bottom rail equivalent. 1 strand the full fence length, secured with hog rings.

Posts, Rail, and Hardware Inventory
- Line posts: 1-5/8 in or 2 in OD galvanized steel. Length = fence height + 24-30 in for in-ground portion.
- Terminal posts (corner, end, gate): 2-3/8 in OD - heavier than line posts. Set in larger concrete footing.
- Top rail: 1-3/8 in OD steel, 21 ft sticks. Sleeves into terminal post brackets.
- Tension bars (stretcher bars): flat steel strip that threads vertically through mesh end loops. One per terminal post.
- Tension bands: wrap around terminal posts to grip tension bars. 3 per 4 ft of post height (one per foot).
- Brace bands and rail ends: connect top rail to terminal posts.
- Tie wires / hog rings: attach mesh to top rail and to tension wire (bottom). About one tie per foot of run on top rail, one per 14 in on tension wire.
- Caps: dome cap on line posts, loop cap (top-rail receiver) on terminals.
- Gate hardware: hinges (one pair per gate), latches, drop pins for double gates.
Field Fence and Welded Wire
Beyond chain-link, the same calculator concept handles:
- Field fence (woven wire): 330 ft rolls in agricultural use. Heights 32, 39, 47 in. Used for livestock and acreage perimeter.
- Welded wire mesh: rigid grid, 4 ft tall x 100 ft rolls. Used for garden fence, deer barriers, light security.
- Barbed wire: 1320 ft (1/4 mile) rolls. 3-5 strands at standard cattle spacing.
- Electric fence wire: polywire or stainless steel high-tensile. Sold by the foot or in 500 lf rolls.
- India: GI chain link sold in 25 m and 50 m rolls, common heights 4, 5, 6 ft. Bamboo or angle-iron posts on village fences.

Common Mistakes
- Ordering mesh by length but forgetting the height roll - you cannot use 5 ft mesh on a 6 ft fence.
- Treating line posts and terminal posts as the same - terminals are heavier (2-3/8 in vs 1-5/8 in).
- Skipping the tension wire at the bottom - the mesh bulges and sags.
- Setting terminal posts too shallow - they hold all the tension and pull out without proper depth and concrete.
- Stretching mesh by hand - use a fence stretcher tool; hand-stretch sags within months.
- Forgetting tension bars at every terminal post - the mesh just attaches to one spot and tears.
- No top rail on a tall fence - the mesh waves in the wind and stays out of shape.
- Vinyl-coated mesh on a sunny site without UV stabilizer rating - it cracks in 3-5 years.
Fence Mesh Calculator FAQ
How many mesh rolls do I need for 200 ft of chain-link?
At 50 ft rolls: 200 / 50 = 4 rolls exactly. If you have any waste or want a buffer for corners, order 5. At 100 ft rolls (commercial): 2 rolls. For terminal posts: 4 minimum (2 corners + 2 ends), more if there are gates.
What is the difference between line posts and terminal posts?
Line posts (1-5/8 to 2 in OD) sit between corners and hold the mesh at intervals. Terminal posts (2-3/8 in OD) at corners, ends, and gates carry the mesh tension and are set in larger concrete footings.
How do I install chain-link mesh?
Set terminal posts in concrete; let cure 24-48 hours. Set line posts. Install top rail. Stretch tension wire along the bottom. Unroll mesh, thread a tension bar through the first row of loops, secure to terminal post with tension bands. Use a fence stretcher to pull the mesh tight, attach to the opposite terminal. Tie mesh to top rail and tension wire with hog rings or tie wires every 12-14 in.
What gauge mesh should I use?
11.5 gauge is residential standard. 9 gauge for higher security. 6 gauge for heavy commercial. Lower gauge number = thicker wire = stronger fence. The number is inverse to thickness, which surprises everyone.
Do I need a top rail?
For fence heights over 4 ft, yes. The top rail keeps the mesh from sagging in the middle of long runs. Tall (8 ft+) commercial fences sometimes use top tension wire instead of top rail with reinforced posts.
How deep should chain-link posts be set?
Line posts: 1/3 of above-ground height. A 6 ft fence needs posts 24 in deep. Terminal posts: same depth but in a 12 in wide hole filled with concrete. Below frost line in cold climates.
Can chain-link be used for pool fencing?
Only if mesh is small enough (most pool codes require less than 1-3/4 in openings) and the bottom rail is within 2 in of the ground. Many jurisdictions ban chain-link for pool barriers entirely - check local code.
How much does a 200 ft chain-link fence cost?
US: $2,000-5,000 installed for 5 ft galvanized. UK: £7,000-16,000. India: ₹50,000-120,000 for GI chain-link at 5 ft height. Add 30-50% for vinyl-coated, taller posts, or gates.
How long does chain-link last?
Galvanized: 20-40 years before significant rust. Vinyl-coated: 15-25 years before the coating fails (then it rusts faster). Stainless steel: 50+ years, expensive.
What is a tension bar?
A flat steel strip threaded vertically through the end loops of mesh at terminal posts. The tension bands wrap around the terminal post and clamp the tension bar, distributing the mesh load. Without tension bars, the mesh tears at the few attachment points.
