What to Write in a Birthday Card
It's time to write your birthday message, and two thoughts are going through your head. One: what do I even write? Two: will my hand survive the physical labor of actually writing it? Both fair. We can't help you with the second one, but for the first, here are some ideas.

How to start your card
Openers are half the battle. Get the first line down and the rest usually just falls out.
- happy birthday to a real one
- HBD to my bff <3
- happy birthday to my actual favorite person
- ok it's your day, let's get into it
- another year of putting up with me, congrats lol
- happy birthday to the best one in the group chat
Heartfelt birthday messages
One honest line beats a whole paragraph of pretty ones. Steal one and make it theirs.
- genuinely so glad you exist. that's the whole card ❤️
- I don't say it enough but I love you and I got so lucky knowing you
- you're the first person I want to tell when something good happens. happy birthday
- hope this year finally hands you the thing you've been quietly working for
- you show up for everybody. today everybody gets to show up for you. love you
- some people you meet and some people you keep. so glad I kept you
- whatever this year throws at you, I'm right here for it. happy birthday
For your mom
Moms keep every single card in a drawer somewhere. make this one hit.
- mom you did all my birthdays first so this one's yours. love you so much
- still don't know how you do all of it. happy birthday, I owe you everything
- thanks for pretending my macaroni necklace was real jewelry. small upgrade here
- you answered every dumb late-night call I ever made. today please just sleep in ❤️
- everything good about me kind of started in your kitchen. love you mom
- mom I get it now. all of it. happy birthday

For your dad
Dad's gonna read it twice and say 'that's real nice' no matter what. keep it short.
- happy birthday dad, the garage is still yours, wouldn't dream of it
- you taught me to check the oil and never pay full price. both still holding up
- happy bday to the only man who narrates his own grilling. love you
- dad I finally figured out the thermostat rules. you win. happy birthday
- everything I fix around the house I fix in your voice lol. love you
For your sister
nobody's got more dirt on you than your sister. use it or don't, your call.
- you knew me before I knew what I was doing and stayed anyway. love you
- happy birthday to my built-in best friend and #1 witness
- we split a whole childhood and you got the better haircut years, so unfair
- you're the only one allowed to roast me, everyone else goes through you
- a sister is just a best friend you're not allowed to quit. lucky me. love you
For a friend
friend cards hit hardest when they mention the one thing only you two know about. these hold you over til then.
- here's to another year of saying 'we should hang soon' and never doing it
- you'd help me move a couch AND actually show up. rare. happy birthday
- you know way too much about me for us to ever stop being friends lol. happy bday
- happy birthday!! whatever you did this year, you were with me. got it?
- so glad the universe assigned me you as a friend. love you bestie
For your grandma
write it big enough to read without the glasses, and mention food. that's the formula.
- grandma nobody's cooking has ever come close. not even close to close ❤️
- you're the only person who never once thinks I call too much. love you
- you make every house feel like your kitchen table. happy birthday grandma
- half my best memories smell like your baking. love you so much
For your husband or wife
you literally live together so generic won't fly. go for the inside joke or the plain true thing.
- marrying you was my best decision, this card is proof I'm still trying lol
- happy birthday love. I loaded the dishwasher your way today. that's the gift
- you still make me laugh at dinner. that's the whole thing I think. love you
- you know exactly how I take my coffee and exactly when not to talk to me before it ❤️
- of all the people I could annoy forever, so glad it's you. happy birthday
For your brother
the rule with brothers is the meaner the card, the more you love them. within reason.
- happy birthday to the reason mom has gray hair. proud of us
- growing up sharing a room with you was terrible. wouldn't trade it
- you're the only person I've fought over a remote with and still like
- happy bday bro. I still owe you for not telling on me that one time. you know the one
- you got taller but I'm still faster. happy birthday anyway
For your son or daughter
you were there for every single one of their birthdays. it's allowed to get a little mushy.
- watching you grow up is my favorite thing I've ever done
- you were the best surprise of my whole life and you still are
- no matter how big you get you're still my kid. happy birthday ❤️
- I made a wish once too. it was you
- proud of you every single day, loudest on this one. love you
- happy birthday kiddo. save me a corner piece
For a coworker or boss
keep it warm, keep it short, keep HR out of it.
- happy birthday! the meeting where we just eat cake starts now
- hope your day has zero emails that start with 'quick question'
- you make this place better and I don't say that in reviews. happy birthday
- happy birthday to the only reason Mondays are survivable here
- enjoy your day, we'll all pretend the deadline moved
For a teacher
teachers get a hundred mugs. a real card with a real line beats all of them.
- thank you for making our kid excited to tell us what happened at school. happy birthday
- you do the hardest job in the building and make it look easy. enjoy your day
- happy birthday from the family that quotes you at dinner now
- our whole house is smarter because of you. hope your day is great
Milestone birthdays: 21st to 60th
big number birthdays want a toast or a roast. pick one and commit.
- happy 21st!! order the fancy drink, tip well, text me you got home
- 21, congrats on being legal everywhere except the rental car counter
- 30 looks good on you!! your twenties were just the rough draft
- welcome to 30 where your back hurts but your taste got SO much better
- 40 is old enough to know better and young enough to do it anyway. happy birthday
- happy 40th, you can now officially complain about the music in restaurants
- 50 years of stories and you're just getting to the good chapters. love you
- happy 50th!! half a century of people being glad you showed up
- 60 is 20 with 40 years of receipts. happy birthday
- happy 60th, you've officially earned the right to leave every party early
Funny birthday messages
The ones that land are a little mean and then a little sweet. Insult, then take it back.
- every year that goes by I realize more and more that we're stuck together. and honestly? maybe it's not so bad
- you're aging like a fine wine, which I know you love, so maybe getting older isn't the worst thing lol
- you're kind of the worst (and also somehow my favorite person, don't let it go to your head)
- I was gonna roast you but you're a year older now and I feel a little bad. happy birthday you old thing
- we've been friends too long for me to leave now, you know way too much. happy bday
- you get more annoying every year and somehow I like you more too, weird how that works
- happy birthday to someone who is genuinely difficult and also completely worth it ❤️
Belated birthday messages
you missed it. own it fast, joke about it once, mean the nice part.
- ok yes I'm late but my love for you runs on its own calendar. happy belated
- happy birthday!! I remembered on the actual day I swear, the card just lost the race
- sorry this is late. the good news is your birthday now lasted two weeks
- I'm late and you have every right to bring this up forever. happy birthday, love you
- belated happy birthday. consider this your bonus round
How to sign off your card
Land the plane. A good sign-off does more work than you'd think.
- love you always
- your #1 fan, forever
- ok now go eat some cake
- happy birthday, from your favorite
- here's to you, always
- now go do something fun
Keep going

Frequently asked
What do you write in a birthday card for someone you don't know well?+
Keep it short and warm. Something like 'Happy birthday, hope this year treats you well' plus one specific thing if you know one ('enjoy the hiking trip'). Two sentences from a coworker reads as thoughtful. Five reads as a little much.
How long should a birthday card message be?+
One to three sentences is plenty. The card itself does the visual work, so the inside just has to sound like you. Got a great story? Tell it in person and put the punchline in the card.
Should the message be funny or heartfelt?+
Match the person, not the occasion. A roast lands with the friend who roasts you right back, and the plain honest line lands with your mom. Can't decide? One funny line then one sincere one covers you.
