100 Best 40th Birthday Wishes

40th Birthday Wishes - feat

When someone you care about reaches their fourth decade, it’s time to tell them what they mean to you with a meaningful 40th birthday message. 

After all, the Big Four-Oh is a big year in terms of birthdays! It’s okay, we have it on good authority that 40 is the new 30. And 30 is… perpetually 25? Anyway, when you’re stuck regarding what to write in the card, here are some ideas for birthday wishes to get you started.

What to Write in a 40th Birthday Card

You thought endlessly reading each and every card at the Hallmark was the hard part, but no. Picking out a funny or sweet card is easy. The challenge comes with what to write inside!

Here are some ideas on what to say and how to say it. Since the first point (and the space allowed on your card) requires brevity in your 40th birthday wishes, you’ll want to only choose a few of these attributes to include in your card.

Keep it short and sweet. Think of a few words that convey what you want to say. Keep it heartfelt – unless of course, you’re going for straight-up witty and funny! Either way, the key to a sweet sentiment or gut-busting humor is to aim for brevity.

Congratulate them on their achievement. Staying alive for forty years is quite the workout. They deserve a pat on the back!

Share a story or memory. Tell them about a time in your relationship that really meant something to you. Whether it is a shared memory that brings joy, a time when they encouraged or helped you, or a reminder of your quirky history together, the stories you share together are a wonderful part of what makes relationships so meaningful.

Share a prayer or blessing. This is a way to show your unity in spirit and your desire for them to experience all that God has for them.

Drop in humor. Everyone loves to laugh!

Sign your name. Don’t forget to tell them who the card is from! Hopefully they’ll know just from your handwriting, but still, it’s polite and helpful to sign off with your love or best wishes.
