Start with a Greeting

“Happy Birthday!” is a simple yet effective way to start a birthday card. It’s also a good idea to use a greeting that reflects the occasion. If you’re sending a birthday card to a child, for instance, you might write something like, “I hope you have a wonderful day.” Or, if you’re sending a birthday greeting to a parent, you might say, “I wish I were there to celebrate with you.”

Picture the greeting of your card like the first line in a play; it sets the tone for the rest of the card. If you’re looking to have more of a sentimental card, try writing something along the lines of, “A day to celebrate one of the most wonderful people I’ve ever met,”. Or, if you want to have a light-hearted and more fun tone to your friend’s birthday card, try writing a greeting like, “Today is [Friend’s birthday date], you know what that means … time to party it up!”

Here are a few sample Happy Birthday Greeting you can write in your friend’s birthday card:

  1. Happy birthday, BFF!
  2. Today is such a perfect day to celebrate a wonderful person like you; happy birthday!
  3. It’s my best friend in the entire world’s birthday (That’s YOU)!
  4. Someone get the birthday boy/girl some cake, stat!
  5. Next to Christmas, the best day of the year is celebrating YOU- happy birthday!
  6. Happy birthday to one of the best people I know!
  7. Who’s got cool friends, is fabulous, and celebrating a birthday today; I’ll give you a hint, they’re reading this card right now!

Share Something About Yourself

If you’re writing a card for a friend’s birthday, there’s no need to go overboard with details. Instead, focus on telling them what they mean to YOU. It might sound cheesy, but it works!

Everyone needs a cute little reminder of what they mean to their loved ones; one of the best days to express that kind of gratitude and love is on a birthday. Think back to when you read a heartfelt message from someone, and they expressed how much you meant to them. Didn’t that make your heart sing? You can bring that soaring feeling straight to your friend on their birthday!

If it’s challenging for you to think of sweet or sentimental things to sprinkle into a card, here are some ideas to get the ball rolling. Remember to put your own personal touch on it; that’s what makes it special!

  1. Share a time when your friend did something for you that meant an awful lot.
  2. Write about an inside joke you both have and how much joy they bring to your life.
  3. Express how your life has changed for the better since they’ve been in your life.
  4. Did your friend teach you something valuable? Share that gratitude with them!
  5. If you and your friend have traveled somewhere together and you had a positive experience, talk about those good times.
  6. Thank your friend for all the memories you two share together, and express how you can’t wait to create more!
  7. Has your friend helped you through a challenging time in your life? Write about how thankful you are to have a friend like them and you couldn’t have gotten through that season of life without them.
  8. Bring up a favorite memory you have with your friend!
  9. Does your friend feel more like a sibling than a BFF? Let them know that and share details of why you feel that way.
  10. Is there a show or movie that means a lot to both of you? Express how close the two of you are by throwing in a playful analogy! Let’s say you both love the TV show Spongebob, and you could say: You’re my best friend; you’re the Spongebob to my Patrick.
