Icelandair allows only 20 centimeters of depth in the cabin, where most of Europe allows 23 to 25. A bag that clears every other European sizer can still fail here, which makes depth the thing to check in Icelandair baggage rules.
The full cabin bag size is 55 by 40 by 20 centimeters, roughly 21.6 by 15.7 by 7.8 inches, at 10 kilograms.
Why the depth matters so much
Standard US carry-ons are 9 inches deep. Icelandair allows 7.8 inches.
That difference is more than an inch, and it is the dimension hard shell cases cannot compress. A soft bag can be squeezed, a rigid one cannot.
Measurements include handles and wheels. Spinner wheels alone often account for the inch you are over by.
The 10 kilogram allowance is generous
Ten kilograms is about 22 pounds for the cabin bag. That beats the 8 kilograms at Lufthansa and SAS.
A small personal item is included alongside it on every fare. Icelandair does not publish dimensions for that item.
So the trade is real: more weight than most European carriers, less depth than any of them.
Higher fares carry two cabin bags
The upper fares allow two cabin bags at 10 kilograms each. Each piece must stay under 115 centimeters in total dimensions.
That 115 centimeter sum is a second test on top of the three individual limits. The maximum frame of 55 by 40 by 20 totals exactly 115.
A bag at full size passes by nothing. Anything oversized in one dimension fails the sum.
Checked baggage rises with the fare
A standard checked bag is 23 kilograms, about 50 pounds. Higher fares raise that to 32 kilograms, about 70 pounds.
Fares run from one cabin bag plus a personal item up to two cabin bags at 10 kilograms each. Checked allowance moves from one 23 kilogram bag to two 32 kilogram bags at the top.
Read the fare name rather than assuming a network default.
How Icelandair baggage rules compare
On weight Icelandair is among the more generous carriers in Europe. On depth it is the strictest we track.
Iberia allows 25 centimeters, five more than Icelandair. British Airways allows 25 as well, with far more width.

Choosing a bag for a Reykjavik connection
Buy or pack a bag that is genuinely under 20 centimeters deep. Do not rely on a case marketed as European cabin size.
Soft sided bags are the safer choice on this airline. They give you back the depth that spinner wheels take away.
Measure the packed bag at its thickest point. Icelandair baggage rules count bulges the same as structure.
The bottom line
Icelandair baggage rules trade depth for weight. You get 10 kilograms, which is good, inside a frame that is shallower than anywhere else in Europe.
Confirm the dimensions in the size checker before you buy luggage for an Iceland trip.
