Phoenix to Tucson is about 138 miles (222 km) by road and 106 miles in a straight line. The drive takes around 2 hr 28 min. The distance is the same in reverse, from Tucson to Phoenix.
What This Distance Means for Your Trip
At 138 miles, this is a driving distance rather than a flying one — and a train or bus is often an option too. A scheduled flight would cover only about 106 miles in the air, and once you factor in getting to the airport, checking in and clearing security, that airport time alone cancels out anything saved aloft. For a trip this length, driving is almost always the practical choice.

How we calculate these figures
Straight-line distance uses the great-circle (haversine) formula between each city's centre coordinates. Road distance applies a circuity factor of roughly 1.2–1.4× to reflect that roads are not straight. Driving time assumes typical blended speeds for a trip of this length, and flight time is the great-circle distance at about 875 km/h cruise plus around 30 minutes for taxi, climb, descent and approach. The door-to-door air estimate adds about three hours for airport access, check-in, security and boarding. Real figures vary with your exact route, traffic, weather, aircraft and connections.
Phoenix to Tucson is Arizona's most straightforward drive — 115 miles south on I-10 through classic Sonoran Desert scenery. It's a comfortable 2-hour trip, easily done as a day trip from either city.
The drive descends gradually from the Phoenix metro through open desert, passing the town of Casa Grande before the landscape gives way to the Rincon and Tucson Mountains framing the approach to Tucson.
Stops Along the Way
