Birthday cards for your sister and wishes

A sister is the person you shared your childhood with — your secrets and countless memories. On her birthday, the right message can say more than a gift. We have prepared a collection of birthday cards for a sister, messages for a sister and wishes for an older sister — for a card, an SMS, a WhatsApp message or a note that comes with a bouquet of flowers. You can choose a short, warm, heartfelt, elegant or lightly funny message and adapt it with her name.

If your sister has kids or you're preparing wishes for the whole family, see cards for a daughter or son or heartfelt messages.

Birthday wishes for your sister

Short messages

„My sister, witness to most of my secrets. Your day is a celebration! Happy birthday!”

„You're at once my oldest friend and my family. Lots of love on your day!”

Warm and sincere messages

„I'm glad I grew up next to you. You were the one I shared everything with, from sweets to dreams. Wishing you a day worthy of your soul and a year full of beautiful moments.”

„However much things change, you remain the first person I call when I need honest advice. Thank you for that — and happy birthday, my sister!”

Heartfelt messages

„We argued over small things and always made up quickly. That's what it means to be sisters. I'd choose you again, every time, and your day is a chance to tell you how much I love you.”

„If I had to choose a family, I'd choose mine just to have you. Have a beautiful day, my sister, and a year full of joy!”

Elegant messages

„Wishing you a year to enjoy everything you've built, with the same elegance and strength you've always had. I'm proud of you and everything you've become.”

„You're proof that some bonds need no explanation. May you be surrounded by peace, light and people who value you as much as I do.”

Original or lightly funny messages

„I've known you since we shared the TV remote, and I keep your secrets more carefully than the Wi-Fi password. Have a great day and happy birthday!”

„In me you have a fan since childhood, with a lifetime subscription. Today we celebrate an extraordinary sister!”

Messages for a flower bouquet

„For my sister, one flower for every year you've been close to me. Happy birthday!”

„The bouquet is from me, but I owe you the hug in person. Have a beautiful day, my sister!”

How to use birthday cards for your sister and wishes

If you found a message you like, you can copy it and send it via WhatsApp, Instagram, Messenger or SMS. Use the message as it is or tweak it slightly by adding the person's name, a personal memory or a few words that represent you. For a more personal card, combine one of the messages with a festive image or a photo dear to you.
