Dallas to Austin is about 237 miles (381 km) by road and 182 miles in a straight line. The drive takes around 4 hr 14 min. The distance is the same in reverse, from Austin to Dallas.
What This Distance Means for Your Trip
At 237 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 182 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.
Dallas to Austin is a classic Texas drive — about 195 miles down I-35 through the heart of the state. The highway passes through Waco, Temple, and Georgetown before descending into Austin's Hill Country approaches.
I-35 is notorious for congestion around Waco, Hillsboro, and especially approaching Austin from the north. Waco makes an excellent halfway stop.

Tips for This Trip
Stop in Waco — it's earned its reputation
Magnolia Market at the Silos draws huge crowds but is worth it. Also stop at the Dr Pepper museum and Cameron Park.
Austin rush hour extends far north on I-35
I-35 approaching Austin backs up badly from as far as Georgetown (30 miles north) during morning and evening rush hours.
US-183 is a decent Austin-bypass alternative
If heading to East Austin or the airport, US-183 avoids the worst of I-35 congestion through downtown.
