Car owners make them according to their own preferences, and they all look different, let alone require the same size. Even at the beginning of last century, when states began to issue official licenses, the sizes were different.
Each state has its own standards, and even within the same state, it will be different with the increase of population. For example, a three-digit number plate is shorter than a four-digit number plate, and so on.
This chaotic situation didn't end until 1956. In this year, all North American automobile manufacturers jointly applied to the government for uniform license plate size, so that they could use a uniform license plate frame when designing cars. In this way, the specification of 6x 12 inch license plate in North America was fixed and has been used ever since.
