Author and curator · FencingCalcs
Francesco Zinghinì is the author and curator of FencingCalcs. This is a truthful role: I am not a licensed fencing contractor, a structural or civil engineer, or any trade professional, and I do not claim any such trade credential.
My relevant, verifiable competence is building deterministic online calculators (open-source Python projects) and electronic-engineering training — rigor on the quantity and cost arithmetic. Every formula on this site shows its basis, every convention is cited under Sources, and every calculator is numerically self-checked against known values (see Methodology).
Everything here follows one rule: the tools must stay correct with no ongoing maintenance. That is why every cost tool works only on the quantities you measure and the prices you enter from your own quotes and bills — the site keeps no material or labor price list, no regional cost database and no live rates that would silently go stale. The only baked-in numbers are stable identities (posts = ceil(line ÷ spacing) + 1, pickets = ceil(line × 12 ÷ (width + gap)), hole volume = π·r²·h, ceil for whole bags, 1 acre = 43,560 ft², 1 rod = 16.5 ft) and clearly labeled industry planning typicals (post spacing, panel/picket widths, post depth, bag yields, coverage, waste %) you can adjust to your own project.
A fence is a real spend, so every cost tool is framed as a planning estimate, not a bid; every quantity tool reminds you to confirm panel/picket dimensions and bag yield on your product and order a little extra for waste and corners; and the reference tools note their values are labeled typicals, not a structural design — call 811 before you dig. The aim is a neutral, free, no-signup reference you can use to sanity-check a contractor’s numbers — nothing that pretends to replace a professional install or an engineer.
