If you’re looking at a map, the distance between Seattle and Tacoma looks like a tiny, insignificant blip. Just two dots on the Puget Sound. But if you’ve actually lived here for more than twenty minutes, you know that "distance" in the Pacific Northwest isn't measured in miles. It’s measured in minutes, moods, and whether or not there’s a stalled semi-truck on the curves near Fife.
Basically, the "official" number is 33 miles.
That’s the standard odometer reading from downtown Seattle to downtown Tacoma. If you’re flying a drone or lucky enough to own a boat, the nautical distance is even shorter—about 26.5 nautical miles (around 30 land miles) if you take the direct water route. But let’s be real. You aren't swimming there. You're likely sitting in a car, gripping a lukewarm coffee, wondering why the GPS says 33 miles but your clock says 75 minutes.
The Reality of the Seattle to Tacoma Commute
Honestly, asking "how far is Tacoma from Seattle" is a trick question. On a Sunday morning at 6:00 AM? You can blast down I-5 in 35 minutes. You'll feel like a champion. During a Tuesday afternoon rainstorm when a Sounders game is letting out? You’re looking at 90 minutes, easily.
The geography of the South Sound creates a bit of a funnel. You’ve got the Puget Sound on one side and heavy industrial zones on the other, meaning Interstate 5 is the primary artery. When it clogs, it really clogs.

Why the 33-mile Drive Feels Longer
There are specific "bottlenecks" that make this drive legendary for all the wrong reasons. The Federal Way curve is a classic. Then there’s the Port of Tacoma exit, where the highway opens up just enough to give you hope before slamming you back into a standstill.
- Mileage: ~33 miles.
- Average Driving Time: 45 to 60 minutes.
- Rush Hour Time: 1 hour 15 minutes to 1 hour 45 minutes.
People often underestimate the "Sea-Tac Factor." Since the airport sits right in the middle, between the two cities, you aren't just competing with commuters. You're competing with every tourist, Uber driver, and flight crew in the region.
Public Transit: The Sounder vs. The 590
If you're over the stress of I-5, you've got options. Some are better than others. The Sounder Train (S Line) is the local favorite. It’s a commuter rail that runs from Tacoma Dome Station to King Street Station in Seattle. It takes about 60 minutes.
The best part? You can actually read a book or stare at the water instead of staring at a bumper.

The Sound Transit 590/594 bus is another workhorse. It’s an express bus that uses the HOV lanes. When traffic is moving, it’s remarkably fast—sometimes hitting downtown Seattle in 50 minutes. But it’s still a bus on a highway. If there’s a wreck, you’re stuck just like everyone else.
The Light Rail Future
As of early 2026, we’re still waiting for the "Grand Connection." The Link Light Rail is slowly creeping south. Currently, it’s pushing through Federal Way, but a direct light rail ride from the Tacoma Dome to Seattle is still a project for the coming years. Once it's finished, the estimated travel time from Federal Way to Tacoma will be about 20 minutes, which will change the "perceived distance" for thousands of people.
Taking the Scenic Route (The Vashon Island "Short-ish" Cut)
You've probably heard someone mention the ferry. It’s a beautiful idea, but it’s rarely a "shortcut" in terms of time. You can drive from Tacoma to Point Defiance, catch the ferry to Tahlequah (the south end of Vashon Island), drive across the island, and take another ferry to Fauntleroy in West Seattle.
It’s stunning. You'll see seals. You might see a whale. But it will take you two hours. It’s a road trip, not a commute.

A Little History: Why These Two Cities Are This Close
Back in the late 1800s, there was a massive rivalry. Tacoma was the "City of Destiny" because it was the chosen terminus for the Northern Pacific Railroad. Seattle was the scrappy underdog that eventually "won" the economic war, partly due to the Klondike Gold Rush.
This historical friction is why the cities grew toward each other. Today, the space between them—places like Kent, Auburn, and Des Moines—has filled in so much that it feels like one giant metropolitan sprawl. You never really leave the city; the scenery just changes from skyscrapers to warehouses to trees and back again.
Tactical Advice for Your Trip
If you’re planning to travel between these two hubs, don't just trust the mileage. Check the WSDOT (Washington State Department of Transportation) app or a real-time map about 15 minutes before you leave.
If the I-5 "red line" looks particularly angry, consider taking Hwy 167. It runs parallel to the east and can sometimes save you a headache, though it has its own bottlenecks in Puyallup.
Pro Tip: If you’re heading to a Seahawks or Mariners game, just take the train. The $5.00 or $6.00 fare is significantly cheaper than the $50.00 you’ll spend on parking, and you won't have to deal with the post-game gridlock that turns that 33-mile drive into a two-hour ordeal.
Next Steps for Your Trip:
- Download the Sound Transit app to check real-time Sounder train schedules; the S Line is the most reliable way to bypass traffic.
- If driving, aim to leave before 2:30 PM or after 6:30 PM to avoid the worst of the southbound "afternoon crawl."
- Check for any active construction on the Puyallup River Bridge area, as lane closures there can double your travel time instantly.
