What size suitcase do I need for checked baggage?

Measuring the size of your luggage isn't tricky. Most airlines require that your bag be 62 linear inches or less. Therefore, your bag's length, width and height cannot exceed 62 inches. This measurement includes the wheels and the handle of your luggage.



For checked baggage in 2026, the standard industry limit for most international and domestic carriers is 62 linear inches (length + width + height). A common suitcase size fitting this requirement is roughly 27 to 30 inches tall, 18 to 20 inches wide, and 10 to 12 inches deep. This is often labeled as a "Large" or "Extra Large" upright spinner. While the size is standard, the weight limit is the more critical factor: in 2026, the standard for Economy is 50 lbs (23 kg), while Business and First Class often allow up to 70 lbs (32 kg). Many airlines have introduced "smart sizers" at check-in that use cameras to measure dimensions instantly. If your bag exceeds 62 linear inches, you will likely face "Oversized" fees starting at $100 to $200. For a one-week trip, a 25-to-27-inch suitcase is usually sufficient and helps ensure you stay under the weight limit to avoid extra charges.
