Happy 21st Birthday: 80+ Wishes and Quotes

A 21st Birthday is one of the most important milestones in anyone’s life. Turning 21 marks you as an adult. In the United States it allows you to drink, gamble and even buy a gun!

Whereas some other countries it is the point where you can vote, get married, adopt a child etc. It’s often seen as officially being the end to childhood as well. So it’s a pretty big deal.

Which means if you know someone about to reach that age then you will want your 21st birthday wishes to be extra special. But don’t worry – whilst knowing what to write in a 21st Birthday card can be tricky it doesn’t have to be.

You can let them know how much they’ve grown, how proud you are of them, or just congratulate them on what is a major landmark in their lives.

So use the wording ideas below to give you some inspiration for writing your own message or just copy your favourite and say Happy 21st Birthday in the best way possible.
