The problem with a number of airplanes is that the overhead compartments that they can work with can be rather small. This is especially troublesome because of how some companies have started to charge people money for storing luggage in cargo compartments. It will help to take a look at the standards that are used because of how many things in luggage, including luggage wheels, can easily influence whether or not something can be stored in a storage compartment.
A standard measurement that is used by most airline carriers involves a standard measure in linear inches. This relates to the sum of the length, width and depth of the luggage in inches. Only one side for each of the three factors will have to be measured here.
A typical piece of luggage will need to be 45 linear inches in size or smaller in order to fit into a storage compartment on a typical airplane. Here is an example of how this can work. A luggage piece that is 25 inches high, 10 inches wide and 6 inches deep will have a total of 41 linear inches to its size. Therefore, it can fit into an average storage compartment.
However, if the some piece of luggage was 15 inches wide it would end up being 46 linear inches in size. This can no longer fit into the compartment and will have to be checked for storage in the standard plane compartment.
The measurements that are used will work with every single piece of the luggage in mind. This includes measurements that relate to the luggage wheels. The length and depth of the luggage will be critical factors to see in the measurement process. The depth will relate to the distance from the front of the bag to the back with plenty of space working with the wheeled suitcase in mind. The length, which relates to how tall it is when upright, can also be influenced by luggage wheels.
It is clear that the sizes of most luggage wheels are relatively small. However, they are going to influence the linear inches of the luggage to the point where there is a potential that the luggage will not be able to fit into a particular area. This is a critical thing to see when getting a piece of luggage stored on any type of airplane or planning the way how it will be reported at an airport.
