How It Works
This tool converts your bag’s weight between kilograms and pounds, then compares it to a typical published weight limit for the category you choose.
How to Use This Tool
- Enter your bag’s weight and select the unit (lb or kg).
- Choose which airline limit category to compare against.
- Click Check to see the converted weight and whether it fits the limit.
Airline weight limits vary by carrier, route, cabin class, and even fare tier, so always confirm the specific limit with your airline before you fly.
The Conversion
- Pounds to kilograms: kg = lb ÷ 2.2046
- Kilograms to pounds: lb = kg × 2.2046
Worked example: a bag that weighs 50 lb is 50 ÷ 2.2046 = 22.7 kg, just under a common 23 kg checked-bag limit. A bag that weighs 24 kg is 24 × 2.2046 = 52.9 lb, which is over a 50 lb limit. That is why it matters which unit your airline uses. A bag can look fine in kilograms and be over the limit in pounds, or the other way around, when you read a scale that uses a different unit than the airline’s policy.
How to Avoid Overweight Baggage Fees
- Weigh at home: A bathroom scale works (weigh yourself holding the bag, then subtract your own weight), or use an inexpensive hanging luggage scale.
- Leave a buffer: Scales differ, and you will probably pick up souvenirs, so aim for a pound or two under the limit.
- Check your airline’s rules: Limits differ by airline, route, fare type, and cabin class, and some count carry-on weight while others only check size.
- Balance across bags: If you have more than one bag, moving heavy items between them can keep each one under its limit.
- Pack heavy items smartly: Shoes, toiletries, and electronics add up quickly. Take only what you will use.
Why Airlines Use Weight Limits
Every pound on an aircraft affects fuel use and balance, and baggage handlers lift bags by hand all day. Weight limits protect workers from injury and keep flights within safe loading limits. Lower fares often come with stricter limits, and fees for overweight or extra bags are one way airlines charge for the extra cost.
Did You Know?
- Many airlines also charge oversize fees separately from overweight fees, based on the bag’s total linear dimensions (length + width + height).
- Some international routes allow two free checked bags in economy, while many domestic US routes only allow one, or none, without a fee.
Frequently Asked Questions
Are these limits accurate for my specific airline?
These are typical published limits used as a general reference; always check your airline’s own baggage policy for your specific route and fare.
What happens if my bag is over the limit?
Most airlines charge an overweight fee, which can be substantial; some may require you to repack into another bag or pay a premium at check-in.
Do carry-on bags have a weight limit too?
Many airlines set a carry-on weight limit, often much lower than for checked bags, while others only limit size. Policies differ widely by airline and country, so check your carrier’s baggage page before you fly.
Does my personal item count toward the weight?
On some airlines, yes. Where carry-on weight is enforced, the limit may apply to the combined weight of your carry-on and personal item. Ask your airline if you are not sure.
Why do different airlines use different units?
Most of the world uses kilograms, while airlines in the United States mainly publish limits in pounds. International itineraries often list both. Use this tool to convert so you are always comparing the same unit.
