Author and curator · FloorsCalcs
Francesco Zinghinì is the author and curator of FloorsCalcs. This is a truthful role: I am not a licensed flooring installer, an NWFA- or CTEF-certified installer or a manufacturer rep, 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 (9 sq ft = 1 sq yd, a 4×8 sheet = 32 sq ft, ceil for whole units, room geometry) and clearly labeled industry planning typicals (waste % by pattern, box/tile coverage, grout/thinset coverage, expansion gap & acclimation) you can adjust to your own project.
A floor is a real spend, so every cost tool is framed as a planning estimate, not a bid; every quantity tool reminds you to confirm coverage on your product’s box and buy 5–10% extra for cuts, waste and future repairs; and the reference tools note their values are labeled typicals. 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.
