Distance Calculator

Italy has no single government-published matrix of road distances between its major cities. ANAS, the state road agency, maintains official lengths for individual autostrade — the A1 “Autostrada del Sole,” Italy’s longest and most important motorway, connects Milan to Naples via Bologna, Florence, and Rome at an official length of roughly 760km, corroborated independently by a separate 2026 travel-guide figure of 754km. Averaging those two gives this tool’s Milan-Naples verified figure of 757km. Milan’s connections to Turin, Bologna, and Genoa are each sourced from a single detailed driving-distance guide.

Worth flagging directly: Rome to Milan is deliberately left unverified after research turned up a genuine internal contradiction — the same source (a car-rental company’s Italy driving guide) quotes 476km for this route on one page and 571km on another, a 20% discrepancy for what should be the identical pair. Rather than pick one figure and present it with false confidence, this route falls back to the GPS-based Haversine estimate instead, the same standard applied to any route this tool can’t verify cleanly.
