For international travel in 2026, the standard for checked luggage is generally 62 linear inches (158 cm), which is calculated by adding the length + width + height of the bag. A typical large suitcase measuring 30 x 20 x 12 inches fits within this limit. Most airlines permit a weight of 50 lbs (23 kg) for Economy class, though some international carriers allow up to 70 lbs (32 kg) for Business or First Class. For carry-on luggage, the industry has moved toward a more universal standard of 22 x 14 x 9 inches (56 x 36 x 23 cm). In 2026, many airlines have installed digital "gate sizers" that use lasers to measure bags; if your suitcase exceeds these dimensions by even an inch, you may be forced to check it at the gate for a fee. It is important to note that low-cost international carriers (like Norse or AirAsia) often have much stricter weight limits for carry-ons, sometimes as low as 15 lbs (7 kg), even if the bag's physical size is correct.
