If you’ve ever been caught off guard by carry-on size rules, you’re not alone. Different airlines have different policies, and it’s easy to get confused. The good news is, with a little planning and some insider tips, you can avoid last-minute surprises at the gate. Here’s everything you need to know about carry-on bag sizes to make your next trip a breeze.

Why Carry-On Size Limits Matter for Travelers
Airlines enforce size restrictions to ensure carry-on bags fit in overhead bins or under seats. Following these rules can save you from extra fees or having to check your bag last minute. Plus, sticking to carry-on limits means less stress and faster airport navigation.
The Standard Carry-On Bag Dimensions You Should Know
Most airlines in the U.S. allow carry-on bags up to 22 x 14 x 9 inches, including wheels and handles. However, budget airlines and international carriers may have smaller limits, so always double-check. A soft-sided bag or backpack is a great option if you want flexibility with dimensions.
Airline-Specific Rules You Need to Check Before Packing
Not all airlines follow the same size guidelines. For example, Southwest Airlines allows slightly larger carry-ons, while budget airlines like Spirit and Frontier have stricter limits. If you’re flying internationally, carriers like Ryanair or EasyJet often allow smaller bags. Always visit the airline’s website for the most accurate information.
Pro Tips for Packing Smart and Staying Within the Limits
1. Use Packing Cubes: They help maximize space and keep things organized.
2. Wear Bulky Items: Save room by wearing jackets, boots, or heavy layers.
3. Roll Your Clothes: Rolling instead of folding saves space and reduces wrinkles.
4. Opt for Travel-Sized Toiletries: Keep liquids under TSA’s 3.4-ounce limit.
5. Measure Before You Go: Use a tape measure to ensure your bag meets size requirements.
