Copying from this blog article:

MySQL has a little know feature for numerical types known as zerofill. This feature effects the display size of numerical types. Unlike the string types the number inside the parentheses is not the storage size in characters for the type. For numerical types the type name itself determines storage size.

The integer type it’s the padding size for zerofill.
