It seems like your question is about average size and growth patterns in males, but it's a bit unclear. If you're asking whether it's common for males to stop growing in height around the ages of 21 and 22, then yes, it is typical for males to reach their full height in their late teens to early twenties. Growth plates in bones usually close after puberty, which limits further height growth.
Regarding the specific measurement you mentioned, if it pertains to a certain attribute (like height or a different measurement), please clarify, and I'd be happy to provide more information. If you're concerned about growth patterns or development, it's always a good idea to consult with a healthcare professional for personalized advice.
