What to Write in a 20th Birthday Card

A 20th birthday is significant because it comes between the milestones of 18 and 21, is the first year after the teens, and marks a new decade. It's also the last decade before people start making jokes about being old, middle-aged, or over the hill.

Since the jokes about being old aren't relevant yet, you'll have to be a little more creative. Inside jokes are great if you know the person well enough, but that's not always possible or appropriate. If you're feeling stumped, use these birthday wishes for inspiration!

Being 20 is like being stuck between a rock and a hard place.

Poems for Someone's 20th Birthday

Poems are a great way to convey a sincere or funny message to someone on their 20th birthday. Use one of these example poems or write one of your own!

You're 20

You're 20 and that's a big deal

Because you're no longer a teen

There's no sadness yet to feel

Your 20s are yet to be seen

20 Looks Good on You

I still can't buy you a beer

But I'll tell you the truth

You're wearing another year

And 20 looks good on you

Change Your View

Being the perfect age must be rough

Being in your physical prime is tough

You're expected to be all grown up

But you're really still just a young pup

20 is just the beginning of getting old

And your next milestone will feel cold

Because 30 is coming soon for you

You'll have to start changing your view

Tips for Writing Birthday Messages

  • Just because someone is having a milestone birthday doesn't mean your specific message has to be related to their age. You have many options for themes, so don't limit yourself.
  • When writing a birthday message, focus on your relationship with the recipient. A card for a coworker should be written differently than a card for your son or daughter.
  • If you're writing a birthday message for a Christian, add a religious element to your note.
  • Be creative and have fun! The more you enjoy writing a birthday card, the more the recipient will enjoy reading it.

Patti, I love your answer to the question. Attitude goes a long way!

Patti on April 28, 2014:

Having reached 70, I certainly believe 20 was not the perfect age. Actually, I never looked back and thought it was the perfect age. 30, 40, and 50 all had different advantages and superior in different ways to being 20. Although I know I am "old" by the world's standards, I love what my mother-in-law used to say: "Old is 15 years older than you are."

Would love to have the strength and stamina I had at 20, but hey I'm not old yet!!

This was great. I love the first one... I think I'm going to write that on my son's 20th birthday card. He's got a couple more years yet but that's one that'll stick in my memory. Great hub.
