Airline Luggage Size Guide: Carry-on Luggage Dimensions

Not sure what size your carry-on should be? You’re not alone. Whether you're a frequent flier or preparing for your first trip, understanding carry on luggage size is essential to avoid surprise fees and travel delays. In this guide, we’ll explain what qualifies as a carry-on, how airline policies differ, and which DELSEY bags meet these requirements.

What Is a Carry-On Bag?

A carry-on bag is a piece of luggage you’re allowed to bring into the aircraft cabin. It typically stores overhead, while a personal item like a backpack or purse fits under the seat. Anything larger must be checked.

Carry-On vs. Personal Item

Carry-On: Roller suitcase, duffel, or backpack stored overhead.
Personal Item: Laptop bag, handbag, or small backpack.
Checked Bag: Larger suitcases transported in cargo.

Standard Carry-On Luggage Size

The most accepted carry on luggage size is:

22" x 14" x 9" (56 x 36 x 23 cm) including wheels and handles
Weight limit: 15–22 lbs (7–10 kg), depending on the airline

Always verify with your airline. You can check TSA guidelines and airline sites for updates.

Carry-On Size by Major Airlines

Dimensions can vary slightly depending on your destination and ticket type. Here’s a quick overview:

Airline Type	Size Limit	Weight Limit
National (e.g., Delta, United)	22" x 14" x 9"	No formal limit
Budget (e.g., Spirit, Frontier)	Smaller, 18"–20"	Up to 40 lbs
International (e.g., Air France, Lufthansa)	21" x 15" x 7"	15–22 lbs

Budget and international carriers tend to have stricter enforcement.

Tips for Choosing the Right Carry-On

Hard vs. Soft Shell: Hardshells offer protection; softsides offer flexibility.
Wheels: Opt for four spinner wheels for better mobility.
Expandable: Useful for flexibility, but may exceed airline limits when expanded.

Can a Backpack Be a Carry-On?

Yes, if it fits within carry-on dimensions. Many travel backpacks are designed to comply with airline regulations.

Do Wheels Count in Carry-On Measurements?

Yes — airlines include wheels and handles in their total size measurements. Always measure from the outermost points.
