Hey there! Great question, and it’s one that comes up often. The general rule for carry-on luggage size is that it shouldn’t exceed 22 x 14 x 9 inches (56 x 36 x 23 cm), including wheels and handles. Weight limits vary by airline, but they typically allow 7–10 kg. Keep in mind some budget airlines, like Ryanair or Wizz Air, may only allow smaller bags unless you pay extra. For a comprehensive guide, I’d recommend checking out this blog post. It explains the rules for major airlines and offers practical tips to avoid surprises at the airport.

It’s always good to know what to expect, especially since stricter rules seem more common these days. I’ll take a look at that resource too—it sounds like a good way to stay prepared for upcoming trips.
