How strict are airlines about hand luggage size?

The most commonly allowed airline carry on size is 56 x 36 x 23 cm (22 x 14 x 9 inches) including all handles, side pockets, and wheels. What is this? This varies by airline, though, with some allowing slightly larger or smaller bags, so check with the airline you plan to travel with.



Airlines have become notoriously strict about hand luggage size in 2026, primarily due to the "carry-on crunch" in overhead bins. Most major carriers have standardized a limit of 22 x 14 x 9 inches, and they now include wheels, handles, and bumpers in those measurements. Many airlines have replaced "sympathetic" gate agents with automated sizers or scanners that do not negotiate; if your bag is even a few millimeters over, it will be flagged for a gate-check (often with a fee). Budget carriers like Spirit or Ryanair are the strictest, enforcing small "personal item" limits and charging upwards of $100 for oversized bags at the gate. International carriers in Europe and Asia are also much stricter about weight limits, often capping carry-ons at 15–22 lbs and weighing them at the check-in desk.
