New York to San Francisco distance

New York to San Francisco by road

The fastest driving route is 2,910 miles (4,684 km) long and takes about 51 hr 15 min without stops or traffic. Almost all of it is on I-80: 2,787 mi of 2,910 mi.

It crosses 11 states: New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Wyoming, Utah, Nevada, and California. The longest stretch is in Nebraska, at 455 mi. That’s an average of 57 mph (91 km/h). AAA recommends a break every two hours or 100 miles: with 25 stops of 20 minutes, the trip takes about 59 hr 35 min. At about 8 hours behind the wheel a day, it’s a 7-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, New York and San Francisco are 2,572 miles (4,139 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.

The road is 13% longer: for every 100 miles in a straight line you drive 113. That’s a normal detour between two cities. Of the 110 US driving pairs in this series, it ranks 60th for detour (the average is 16%).

From New York, San Francisco lies to the west (bearing 282°), and from San Francisco, New York lies to the east. The straight line reaches San Francisco on a bearing of 250°: 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 New York and San Francisco

Halfway along the straight line, 1,286 miles (2,070 km) from each city, is the point 41.8579° N, 98.7504° W. It falls near Ericson (Nebraska, pop. 90), 6.5 mi away.

By road, the halfway point is 1,455 miles (2,342 km) from each city, near Overton (Nebraska, pop. 594), 8.4 mi away. The two midpoints are 92.5 mi apart: if you want to meet halfway, the one on the road is the useful one.

Time difference and flight

San Francisco is 3 hours behind New York all year (Pacific Time versus Eastern Time): when it’s 12:00 in New York, it’s 9:00 in San Francisco.

A direct flight would take about 5 hr 40 min. That’s an estimate: 30 minutes for takeoff, climb, descent and landing, plus the 4,139 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. Westbound flights usually take a little longer than eastbound ones because of high-altitude winds (the jet stream).

The two cities

New York and San Francisco sit at almost the same elevation: 35 ft (11 m) and 55 ft (17 m).

New York has 8.6 million people and San Francisco 826,079 people (Census Bureau estimate for 2025).
