What to write in a Birthday card
A birthday message only needs to do one thing: make them feel seen. Here's how to write one that sounds like you and not like the back of a shop card.
Start with the person, not the milestone. Before you write a word, picture them: the thing they're brilliant at, the way they make a room easier, the in-joke only the two of you share. One genuine, specific detail is worth more than a paragraph of well-wishing.
Then decide what you actually want them to feel when they read it - celebrated, missed, proud, or just quietly known. Write toward that, keep it short, and resist the urge to be clever at the expense of being warm. Warm always wins on a birthday.

How to get it right
Name one specific thing
Mention a quality or memory that's true of them and nobody else.
Say it out loud first
If it sounds like something you'd actually say, it'll read as sincere.
Lead with them
Make the message about who they are, not the number of candles.
End on a wish
Close with what you hope this year brings them and stop there.
For a close friend
Happy birthday to the friend who's seen me at my worst and stuck around anyway. Genuinely lucky to know you.
Another trip around the sun for my favourite partner in nonsense. Let's mark it properly soon.
You're one of the good ones, and I don't say that lightly. Have the day you deserve.
Every year I'm more grateful you're in my corner. Happy birthday, you absolute legend.
Cheers to you today - the friend who shows up, every time. Hope it's a brilliant one.
For family
Happy birthday to someone who's been quietly holding this family together for as long as I can remember.
However many candles there are this year, you don't look a day past wonderful. Have a lovely one.
Wishing you a birthday as warm and generous as you've always been with the rest of us.
Hope today is slow, happy, and full of all your favourite things. You've earned the fuss.
Thinking of you on your birthday and counting the ways I'm glad you're mine.
Short and sweet
Happy birthday - go and make a fuss of yourself today.
Hope your day is exactly as good as you are.
Cheers to another year of being brilliant.
Sending you the happiest of birthdays and a proper celebration soon.
A little playful
Happy birthday! Statistically you're now too old for excuses and too young to be sensible. Perfect.
Another year wiser, allegedly. Have a cracking day anyway.
Congratulations on surviving another lap. Cake is mandatory.
You're not older, you're just a limited edition that's appreciating in value. Happy birthday.
Questions
What if I don't know them very well?
Keep it warm and general - a sincere 'hope you have a wonderful day' beats a forced inside joke. Sincerity reads better than familiarity you don't have.
How long should a birthday message be?
One to three sentences is plenty. A short, specific line lands harder than a long, generic paragraph - people remember the detail, not the word count.
Stuck on the words? Don't be.
