Pro Tip

The best birthday messages have three parts: (1) a specific compliment about who they are, not just "happy birthday," (2) a favorite memory from the past year, and (3) one thing you're excited about for their next year. This formula works for kids, adults, and everyone in between.

Frequently Asked Questions

What should I write in a birthday card?

Start with "Happy birthday" and the person's name, then add a personal touch — a shared memory, something you admire about them, or a wish for their year ahead. Keep it to 2-4 sentences. The best birthday card messages feel personal and specific rather than generic.

How do you write a heartfelt birthday message?

A heartfelt birthday message focuses on your genuine feelings about the person. Mention a specific quality you love about them, a memory you cherish, or how they have impacted your life. Use simple, sincere language rather than flowery phrases. Authenticity always beats perfection.

What is a good funny birthday message?

The best funny birthday messages are lighthearted and affectionate — they make the person laugh without being mean. Jokes about getting older, playful sibling rivalry, or self-deprecating humor about your gift-giving skills all work well. Keep it warm and make sure the humor matches your relationship.

What do you write in a kids birthday card?

For kids, keep it simple and enthusiastic. Use short sentences, mention their age ("You are 7 — that is so cool!"), and reference something they love (a hobby, favorite character, or recent achievement). End with an exclamation point and a wish for a fun birthday party.

How long should a birthday card message be?

The ideal birthday card message is 2-4 sentences. One sentence for the birthday wish, one or two for the personal touch, and one for a forward-looking wish. Anything longer than a short paragraph feels like a letter, not a card. Quality beats quantity — a short, specific message is better than a long, generic one.

What do you write in a coworker birthday card?

For coworkers, keep it friendly but professional. A simple "Happy birthday! Hope you have a great day" works well. You can add a brief positive comment about working with them or wish them a great year ahead. Avoid inside jokes unless you are close, and keep it to 1-2 sentences.
