Busan vs. Daegu: Which South Korean City Is Bigger?

Busan is larger than Daegu by population—but Daegu edges it out in land area. Here's the breakdown:

Key Differences

• Busan: South Korea's #2 city, #1 port (6th busiest globally), coastal, temperate, logistics/shipbuilding/finance hub, Haeundae Beach, Jagalchi Market, Busan International Film Festival.
• Daegu: #4 city, inland basin (hotter summers, colder winters), textile/fashion/tech/medical hub, historic herbal medicine market (Yangnyeongsi), gateway to Gayasan National Park (Haeinsa Temple).

Why the Confusion?

Daegu's administrative area is larger because it incorporates more surrounding mountains and farmland. Busan's geography—mountains meeting sea—constrains its footprint, concentrating density along the coast.

For travelers: Busan offers beaches, seafood, maritime energy. Daegu offers history, textiles, mountain access, slower pace. Both are served by KTX high-speed rail (Seoul–Busan: 2.5 hrs; Seoul–Daegu: 1.5 hrs).
