It is always advisable to know the exact suitcase size before you use it on your flight.

If you are traveling with a large carry on bag, make sure it is compliant with the airline carry on size.

If not, checked baggage fees will apply if you get caught.

But if you are planning to take the risk anyways it is better to use a soft sided bag, because it can be squeezed easily in the sizer also in the overhead compartment or under the seat in front of you.
