Field Fence Calculator — Rolls, T-Posts & Clips
Farm fence math is rolls and posts: woven field fence comes in 330-ft rolls, welded wire in 100-ft rolls, and T-posts go every 8–12 ft. This field fence calculator takes your linear footage and fence type and returns roll counts, T-post counts, and clip counts, with 2026 material costs. Use wood H-braces at corners and gates — T-posts are for the straight runs, not for holding tension at a corner.
660 ft is ⅛ mile; 1,320 ft is ¼ mile
Show the math
Rolls = ⌈660.0 ÷ 330.0⌉ = 2
T-posts = ⌈660.0 ÷ 10⌉ + 1 = 67
Clips = 67 (one per T-post)
Materials = 2 × $180.0–$280.0/roll + 67 × $5–$8/post
What the numbers mean
The calculator converts your measurements into a practical purchase quantity using a documented coverage or spacing assumption.
Any whole-unit quantity is rounded up so the result does not leave you short during the project.
Use the cost range as a planning baseline and confirm the final quantity, availability, and delivery charge with your local supplier.

Pro tips
- Corners and gates get wood H-braces, never T-posts — all the fence's tension lands on the corners.
- Stretch woven wire with a come-along or fence stretcher; hand-pulled wire sags within a year.
- Keep the bottom wire 4–6 in off the ground — wire buried in soil rusts through and gives predators a gap.
- For horses, step up to 60-in fence; 47-in field fence is sized for cattle, sheep, and goats.
- Buy 10% extra clips — they're cheap, tiny, and vanish into grass the moment you open the bag.
- An eighth of a mile (660 ft) of woven field fence needs 2 rolls, 67 T-posts, and 67 clips — roughly $700–$1,100 in materials.
Common questions
Frequently asked questions
How much field fence for 660 feet?
Two 330-ft rolls of woven wire, 67 T-posts at 10-ft spacing, and 67 clips.
How much for a quarter mile (1,320 ft)?
Four 330-ft rolls and 133 T-posts.
What if I use welded wire instead?
660 ft ÷ 100-ft rolls = 7 rolls — same 67 T-posts.
Do corners need special posts?
Yes — wood H-brace assemblies at every corner, gate, and direction change; T-posts can't hold wire tension.
How tall should field fence be?
47 in is standard for cattle and sheep; 60 in for horses or deer pressure.
What does 660 ft of field fence cost in materials?
About $700–$1,100: $360–$560 in wire plus $335–$536 in T-posts.
