On most international flights from the US, the maximum size for a checked bag is 62 linear inches (158 cm), calculated as length + width + height, including wheels and handles, with a standard weight limit of 50 lbs (23 kg) in Economy.
One wrong measurement and you’re paying a $100–$200 surprise fee at check-in. The 62-inch rule sounds simple, but wheels and handles count, the “28-inch” label on your suitcase is only one dimension, and a handful of airlines have limits that are nothing like the standard. Here’s exactly how to measure your bag, which airlines break the pattern, and the weight caps that apply to your ticket class.
What Is The Exact Checked Luggage Size Limit For International Flights?
The universal standard is **62 linear inches (158 cm)**. This is the sum of the bag’s total outside dimensions: length + width + height. The measurement must include every protrusion — wheels, handles, side pockets, and protective bumpers. A typical medium suitcase that fits the limit measures roughly 27″ x 21″ x 14″. The weight limit for standard Economy tickets is **50 lbs (23 kg)**, while Premium, Business, and First class tickets generally allow **70 lbs (32 kg)**.
How To Measure Your Suitcase The Right Way
Measuring the bag body and ignoring what sticks out is the most common reason for a rejected bag. Follow these official steps:
- Place the bag on a hard floor with the wheels down and the handle fully extended.
- Measure the total height from the floor to the tallest point (usually the top handle).
- Measure the total width from the leftmost point (wheel) to the rightmost point (wheel).
- Measure the total depth from the front face to the rearmost point (handle or back panel).
- Add all three numbers together. If the sum is over 62 inches, the bag is oversize on virtually every major airline.
- Compare to the manufacturer’s external dimensions — the “28-inch” tag on a bag refers only to its height, not the total linear inches.

Standard Weight Limits By Class
The weight limit depends more on your ticket class than the airline itself. These are the most common caps:
| Class of Service | Standard Weight Limit | Common Exceptions |
|---|---|---|
| Economy | 50 lbs (23 kg) | Flights to/from Australia and New Zealand often allow 70 lbs (32 kg). |
| Premium Economy | 70 lbs (32 kg) | American Airlines and many carriers grant this tier the same 70 lb limit as Business. |
| Business / First | 70 lbs (32 kg) | Cuba routes and flights bound for Brazil sometimes cap at the same 70 lb max. |
The 50 lb limit is not arbitrary — the International Air Transport Association (IATA) recommends it as an occupational health and safety guideline to protect baggage handlers from injury. Bags over 32 kg (70 lbs) are frequently refused or require mandatory repacking.
Which Airlines Use A Different Limit?
While most global carriers follow the 62-inch rule, a few have allowances that are dramatically larger. These aren’t mistakes; they’re the airline’s published policies.
| Airline | Maximum Linear Inches | Notes |
|---|---|---|
| British Airways | Approx. 208 inches (529 cm) | The official dimensions are much larger; the practical limit is still often weight-based. |
| Norwegian | Up to 441 inches (1,120 cm) | Extraordinary allowance; check your specific route’s luggage page. |
| Ryanair | Approx. 319 inches (810 cm) | Low-cost carrier with a huge linear allowance but strict weight and bag-count rules. |
| Wizz Air | Approx. 439 inches (1,115 cm) | Similar to Ryanair — generous dimensions, tight weight enforcement. |
Even with a generous linear allowance, weight limits still apply.
2026 Fee Changes That Affect Your Bag
As of May 18, 2026, American Airlines updated its fee structure. These are now the standard charges for international flights originating in the US, Canada, Mexico, or the Caribbean:
- First checked bag: $50 at the airport, $45 if paid online during check-in.
- Second checked bag: $60 at the airport, $55 if paid online.
- Basic Economy first bag: $55 at the airport, $50 if paid online.
Oversized or overweight bags that exceed 62 inches or 50 lbs typically trigger a surcharge of **$100–$200**, depending on the airline and route. Budget carriers like Spirit and Frontier often charge more than major airlines for these penalties.
Checked Luggage Size for International Travel: Final Rules Checklist
Before you leave for the airport:
- Measure your bag from wheel tip to handle top — that total must be 62 linear inches or less on any major airline.
- Weigh the loaded bag: 50 lbs max for Economy; 70 lbs max if you hold a Premium, Business, or First ticket (or fly to Australia/New Zealand).
- Confirm your specific airline’s rules — British Airways, Norwegian, Ryanair, and Wizz Air have much larger linear allowances, but weight limits remain tight.
- Pay bag fees online during check-in to save $5–$10 per bag on airlines like American.
- Remember that the checked limit is different from the carry-on limit — international flights often allow a larger checked bag but a smaller carry-on than domestic US flights.
FAQs
Does the 62-inch limit include wheels and handles?
Yes. All outside projections — wheels, handles, side pockets, and protective bumpers — must be included in the measurement. Measuring only the main body is the most common mistake that leads to an oversize fee.
Can I use a 28-inch suitcase for international travel?
It depends on the other dimensions. A 28-inch tall bag that is also 20 inches wide and 12 inches deep comes to exactly 60 linear inches — within the limit. The same bag at 21 inches wide would hit 61 inches, leaving no margin for error.
What happens if my bag is one inch over 62 inches?
Most airlines will charge an oversize fee, typically $100 to $200, and may still accept the bag at the check-in agent’s discretion. On strict carriers, the bag could be refused, forcing you to repack or ship it separately.
Are checked luggage size limits the same for all countries?
A few local carriers within Europe or Asia may have metric-based limits like 158 cm total, which is identical. The main difference is weight — some international routes outside the US cap Economy at 44 lbs (20 kg).
How many checked bags am I allowed on an international flight?
Most international itineraries allow 1–2 checked bags per passenger. American Airlines permits up to 10 bags on Trans-Atlantic and Trans-Pacific routes, but 5 bags for Mexico, Caribbean, and South America flights. Check your ticket’s allowance before packing more than two.
