Fencing Calculators: Every Tool You Need to Plan a Fence
Every fence estimate starts with the same core number: how many posts the run needs, based on total length and post spacing. From there, rail count, panel count, picket count, and concrete quantity all follow — which is why a single wrong post-spacing assumption can throw off an entire materials list.
This page collects all 8 of our free fencing calculators, covering wood, vinyl, and chain link fence types, along with post depth, concrete, gate hardware, and stain coverage. Each calculator links to a full guide walking through the trade rules of thumb — post spacing, burial depth, hinge sizing — that professional fence installers use.
All Fencing Calculators
Fence Materials Calculator
Calculate post count, rail sections, and picket count for a wood fence from length and spacing.
Fence Cost Estimator
Estimate total fence cost combining per-linear-foot pricing with flat gate costs.
Fence Post Length Calculator
Find the actual post length to buy once burial depth is factored in — always longer than the visible fence.
Fence Post Concrete Calculator
Calculate how many bags of concrete each post hole needs after subtracting the post’s own volume.
Chain Link Fence Calculator
Calculate fabric rolls, line posts, terminal posts, and tension wire for a chain link fence.
Vinyl Fence Panel Calculator
Calculate pre-made panel count and post count, accounting for gate openings.
Fence Gate Hardware Calculator
Calculate hinges, latches, and drop rods needed for single and double gates.
Fence Stain & Paint Coverage Calculator
Calculate gallons of stain or paint needed based on fence area, sides, and coats.
Frequently Asked Questions
Which fencing calculator should I start with?
Start with the Fence Materials Calculator to get your post count and layout, since post count and spacing feed directly into the concrete, gate hardware, and stain calculators.
Do I need a different post length calculation for a taller fence?
Yes — the Fence Post Length Calculator adjusts for this. Taller fences and looser soil conditions typically need a higher percentage of the post buried underground for adequate stability.
Can I use the chain link calculator for a wood fence?
No — use the Fence Materials Calculator for wood or the Vinyl Fence Panel Calculator for vinyl. The Chain Link Calculator is specific to fabric rolls, line posts, terminal posts, and tension wire.
