What to write in a 21st birthday card
For that first big milestone to kick start their twenties, make sure they know you’re by their side to celebrate the moment. 21 is for having fun, so share a message that starts the year as it should go on…
“Your twenties are a wild ride, buckle up!”

“Happy 30th! Now let’s party like you’re still in your twenties!”
“30 looks SO good on you. I’ve got a feeling this one might be your best yet.”
“A little bit older but a whole lot wiser. We loved you then, we love you now.”
“Happy 30th to my best friend EVER. Thanks for sticking by me through the decades”
“Thirty and thriving – today is all about celebrating YOU!”
What to write in a 40th, 50th or 60th birthday card
Big birthdays are made for reflection, but always with a lot of love, cake and caring way less about the little things. Tell them they're getting better every decade with a message made for a memorable milestone.
“I’m so pleased to celebrate this super exciting birthday with you – here’s to ageing like a fine wine!”
“Another decade full of achievements and adventures, we can’t wait to see what the next one holds for you.”
“ Tonight is all about celebrating YOU. Happy big birthday, we love you so very much”
“Another decade – go you! Put your feet up and relax, you deserve it.”
“The best thing about new decades is the chance to start again, it’s never too late to do everything you’ve dreamed of.”
What to write in a 70th, 80th or 90th birthday card
They’ve already brightened the days of so many, but a message for a special someone celebrating a 70th, 80th or 90th birthday can let them know that there are years of wonderful moments yet to come.
“Happy birthday to simply the best, you make us all so proud every year.”
“Happy birthday, we love you. Now sit back and enjoy a day all about you!”
“You’ve been there for me for all my life, now let us celebrate you – we can’t imagine a world without your love.”
“Wow, what a milestone – we’re so excited for the next decade of fun! Remember, you’re as young as you feel.”
“What an icon you are to look up to, another decade past and looking better than ever!”
What to write in a 100th birthday card
The ultimate milestone – 100 times around the sun. Alongside a timely telegram from His Majesty, make your birthday card message something the whole family will truly cherish forever.
“100 years young, you don’t look a day over 21! What an inspiration you are.”
“What an achievement. Happy 100th Birthday to you.”
“Happy Birthday! We could listen to stories of your adventures for another 100 years!”
“100 today, but still the best fun around. They just don’t make them like you anymore.”
“100 years and still putting everyone else first. Today, just relax. We’re all here to celebrate you.”
