Atlanta to Miami distance

Atlanta to Miami by road

The fastest driving route is 660 miles (1,063 km) long and takes about 12 hr without stops or traffic. Almost all of it is on I-75: 367 mi of 660 mi.

It goes through 2 states: Georgia (241 mi) and Florida (419 mi). That’s an average of 55 mph (88 km/h). AAA recommends a break every two hours or 100 miles: with 6 stops of 20 minutes, the trip takes about 14 hr. At about 8 hours behind the wheel a day, it’s a 2-day drive. The time is OSRM’s estimate with OpenStreetMap data: no traffic and speeds somewhat below the limits, so real trips can differ.

Straight-line distance and bearing

In a straight line, the shortest distance over the Earth’s surface, Atlanta and Miami are 604 miles (972 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.

The road is 9% longer: for every 100 miles in a straight line you drive 109. The route runs almost straight. Of the 110 US driving pairs in this series, it ranks 87th for detour (the average is 16%).

From Atlanta, Miami lies to the southeast (bearing 154°), and from Miami, Atlanta lies to the northwest. The straight line reaches Miami on a bearing of 156°: on a sphere the bearing keeps changing along the way, which is why the shortest route looks slightly curved on a flat map.

Halfway between Atlanta and Miami

Halfway along the straight line, 302 miles (486 km) from each city, is the point 29.7794° N, 82.2076° W. It falls near Hampton (Florida, pop. 502), 7.1 mi away. The nearest town of 20,000 people or more is World Golf Village (Florida, pop. 26,077), 45.0 mi away.

The nearest town of 20,000 people or more is Liberty Triangle (Florida, pop. 24,888), 36.7 mi away. The two midpoints are 16.0 mi apart: if you want to meet halfway, the one on the road is the useful one.

Time zone and flight

Atlanta and Miami share the same time all year: both are on Eastern Time.

A direct flight would take about 1 hr 45 min. That’s an estimate: 30 minutes for takeoff, climb, descent and landing, plus the 972 km straight line at 800 km/h (about 497 mph), a typical airliner cruising speed. Real schedules depend on wind, routing and airports, and not every pair has a direct flight.
