What to Write in a Birthday Card: Messages for Everyone on Your List

A good birthday message has three parts: a greeting, one personal line, and a wish for the year ahead. "Happy birthday, Sam! I still laugh about our road trip to Banff. Here's to a year as fun as you are." Below are lines for everyone on your list — copy one and add a memory of your own.

What should you write in a birthday card?

Start with their name, add something only you would say — a memory, an inside joke, something you admire — and finish with a wish. Even two sentences feel personal when the middle one is specific.
