Not all airplanes of the same model have the same size bins. Even on board an airplane, there can be one size bin above the aisle and window seats and a different size above the center seats.

The maximum that can fit the bins will probably be larger than the maximum allowed carry on, so go by the airline's maximum size for the airlines that you fly.

It doesn't matter if it fits in the bin or not, it matters that it's not larger than whatever size the airline says it has to be smaller than.
