80+ 40th Birthday Wishes for Friend (Heartfelt & Funny)

Looking for the right 40th birthday wishes for friend? Forty is a quiet milestone: the dreams of your twenties have met the lessons of your thirties, and the best of your character is just getting started. A friend who has stood beside someone through all of that deserves words that are warm, honest and a little bit smiling. Below you will find more than ninety original wishes, from heartfelt to short to gently funny, plus sample card notes and tips. If you are celebrating a bigger milestone, our 50th birthday wishes are ready too.

Quick Tips for Writing the Perfect Message

1. Start with one real memory, even a small one. A shared walk, a favour you never forgot or a long phone call says more than a general compliment.
2. Mention a quality you admire in your friend, such as patience, honesty or generosity. Forty is a good year to hear what kind of person you have become.
3. Keep humour kind. Joking about age is fine; joking about looks, health or struggles is not.
4. Add a good wish for the year ahead: health, peace of mind, a happy home and time with family.
5. Match length to the medium. A card can hold a paragraph, a text is best in one or two lines, and a call can be the longest of all.
