Luggage Size Checker for Airline Carry-on and Checked Bag Limits
This luggage size checker tells you whether your bag fits the airline's carry-on and checked baggage limits before you reach the airport. Pick your airline, enter your bag's dimensions and weight, and see an instant Accepted or Exceeds Limit verdict. It is built for anyone packing for a flight who wants to skip surprise gate fees and last-minute repacking.
Every airline sets its own rules, so a bag accepted on one carrier may be rejected on another. With baggage policies for 39 airlines across six regions, the tool compares each dimension and the weight against the airline you actually fly, covering both Carry-on and Checked Baggage in metric or imperial units.
How to Use the Luggage Checker
Select your airline
Open the airline selector and type to search by name or IATA code, such as "AA" for American Airlines. Airlines are grouped by region, and the limits reference card appears as soon as you choose one.
Choose the bag type
Switch between the Carry-on and Checked Baggage tabs. The reference card updates automatically to show the rules that apply to that bag type.
Enter dimensions and weight
Type the length, width, and height of your bag. The linear total (L + W + H) calculates as you go. Add the weight too, and toggle between metric (cm/kg) and imperial (in/lbs) to convert every value at once.
Check the result
Press Check Luggage. Each dimension is compared individually against the limit with a color-coded progress bar, ending in a clear Accepted or Exceeds Limit verdict. On the Checked Baggage tab, use Add Bag to track several bags and their running total weight.

Frequently Asked Questions
How should I measure my luggage?
Measure the longest point of each dimension, including wheels, handles, and any external pockets. Airlines measure bags at their maximum extent, so a telescoping handle or spinner wheels count toward the total size.
What is the "linear total" and how do I read linear inches?
The linear total (also called linear inches or overall dimensions) is the sum of length + width + height. Many airlines use this single number as their checked baggage size limit, typically 158 cm (62 inches) for full-service carriers. The checker adds your three measurements automatically and compares the result against the airline's maximum.
What is the standard carry-on size?
There is no single global standard. Most carriers cap carry-on bags at roughly 55-56 cm tall, but budget airlines are often stricter and many enforce a weight limit such as 7-10 kg. Because the exact figures vary by airline, select your carrier in the tool to see its precise carry-on dimensions and weight allowance.
Why do some airlines show "No weight limit" for carry-on?
Most US domestic airlines such as American, United, Delta, and Southwest do not publish a specific carry-on weight limit. Your bag must still fit the overhead bin and you should be able to lift it yourself, and some international airports may weigh cabin bags even for these carriers.
What does "0 free checked bags" mean?
It means the airline's basic economy fare includes no free checked baggage, so you pay a fee to check a bag. Many US carriers and budget airlines work this way. Higher fare classes, loyalty status, or co-branded credit cards may add free checked bags.
What happens if my bag is oversized or overweight?
You will usually pay an oversize or overweight fee at the gate or check-in desk, often far more than booking the allowance in advance, and an oversized carry-on may be forced into the hold. Checking before you leave home lets you repack or switch bags to avoid the charge.
Are the airline limits always accurate?
The tool uses commonly published airline baggage policies, but airlines update their rules and limits can vary by route, fare class, or frequent flyer status. Always confirm with the airline's official website before traveling, especially for international flights.
Can I check bags for connecting flights on different airlines?
Check each airline on your itinerary separately, because your bag must comply with the most restrictive carrier you fly. Use the airline selector to switch carriers and compare their limits.
