How does KLM's carry-on limit compare?
By volume, KLM's box is larger than 14 and smaller than 11 of the 27 carry-on limits on this site. Within a centimetre on every side, it is the same box as Air France. Spirit, easyJet and Frontier publish the most generous limits. The tightest published limits are Icelandair, Ryanair and Breeze, so a bag bought for KLM can fail there.

Frequently asked questions
What are the KLM carry-on dimensions in inches?
KLM publishes 55 x 35 x 25 cm, which is 21.7 x 13.8 x 9.8 in (converted). Compare in the unit KLM publishes and keep the decimals: rounding a converted limit up is how a bag that fits on paper fails the sizer.
How strict is KLM about carry-on size?
KLM does not publish an enforcement policy, and gate checks vary by airport and by how full the flight is, so treat 55 x 35 x 25 cm as the rule rather than a guideline: a bag that goes into the sizer with wheels and handles has nothing to argue about. 1 of the 15 popular carry-ons checked on this page meet it when measured with wheels.
What is the KLM personal item size limit?
KLM limits the under-seat personal item to 40 x 30 x 15 cm. It is a separate allowance from the carry-on; the KLM personal item page on this site lists the bags that meet it.
What is the KLM carry-on size limit?
KLM’s own baggage page gives the carry-on limit as 55 x 35 x 25 cm. Including handles and wheels. A Basic ticket allows only the small bag. Measure the bag with wheels and handles, standing up, and compare the longest side with the longest limit.
Does KLM weigh carry-on bags?
KLM states a carry-on weight limit of 12 kg (26.5 lb). Economy: 12 kg for everything you bring into the cabin combined.
Will a 22 x 14 x 9 inch bag fit KLM?
No, not by the published figure. A 22 x 14 x 9 inch bag converts to 55.9 x 35.6 x 22.9 cm and is 0.9 cm over KLM’s limit on its tightest side. A 21 inch carry-on around 53 to 54 cm tall is the safer choice for this airline.
Is the KLM carry-on included in the fare?
On the page read for this site, the carry-on is fare-dependent (check your fare rules). Basic or light fares at some airlines restrict the overhead bag, so confirm what your specific ticket includes before you pack.
Researched, not professional advice. Airline limits change without notice and can differ by route, aircraft and fare; the airline's own page is the final word.
