How to Write a Sweet 16 Card

  1. Start with "Happy sweet 16" and their name.
  2. Say what you admire about them. Their kindness, their sense of humor or how hard they work.
  3. Add a wish for the year ahead. A new license, a new school year or simply a fun year.
  4. Close with love. Sign with your name, even if they know your handwriting.

Frequently Asked Questions

What should I write in a sweet 16 card?

Wish them a happy sweet 16 by name, say one thing you admire about them, and add a wish for the year ahead. Three or four sentences is plenty.

Is a sweet 16 only for girls?

The phrase sweet 16 is most often used for girls, but a 16th birthday is a milestone for anyone. For a boy, "Happy 16th birthday" is the more common wording.

What is a short message for a sweet 16 card?

"Happy sweet 16! We are so proud of you" and "Hope your sweet 16 is everything you wanted it to be" are both short enough for a group card.
