There is no right age for a master’s in the USA and no age limit. Many students start in their early to mid 20s right after a bachelor’s, but programs routinely admit students in their 30s, 40s, and beyond. Schools care about your background and goals, not your birth year.
Starting young has trade offs. You finish earlier and have more working years ahead, but you bring less work experience to class discussions and job hunts. Starting later means you study with clearer goals and often with an employer helping to pay, but you juggle more outside commitments.
The better question is whether the timing fits your life. Do you have the money or funding, the time to study, and a clear reason for the degree? If the answer is yes, your age is not the obstacle. If the answer is no, waiting a year or two is fine.
