3 Letter Ideas To Best Friend On Her Birthday(+Wishes)

A great birthday wish can do a wonderful job of showing your best friend just how important they are for you. We all know that family members play a very important part of every person’s life, but we can’t take our friends out of this equation. We spend so much time together with them, learn new things together, dream about the future, and many other things. That’s why your best friend, who went with you through sick and thin, deserves the very best birthday wish from you. Today I will share with you some great letter variations, as well as short and long bday wishes to impress your bestie!

Let’s start with the basics. Even if you think you are not a talented person when it comes to writing, I will reassure you right now. We all go to school, and there they give us a pretty cool structure for writing literally anything: beginning, main part, conclusion. Just stick with this simple layout, so no matter what you write, it will look polished and pretty professional. Don’t worry, I won’t leave you hanging on that, here is a detailed list of what you can write in each part:

  • Beginning. Here you write your friend’s name( Dear Stacy,) and then give some very general information stating the fact that it’s your friend’s birthday, and how happy you are to be a part of it.
  • Main part. The easiest way to write this part is to list in details a few examples of your latest( or even childhood) adventures, how they made you feel, and state the fact that it would never have happened if not for your friend.
  • Ending. The best writing works have a loop structure, meaning you need to finish what you have started with. So here you can say how excited you are to have such a wonderful friend in your life, how your friend makes you feel, list a few things your friend has helped you with. And then finish the letter with the closing line of your choice, for example, “A friend you can’t live without” and your name.

Here is an example of my structure:

To the very best friend in the world,

I just can’t believe one of my closest friends is already (Age). You don’t look that age, though. I am so grateful to be a part of this wonderful day.

Thank you so much for all the support you have been giving me when I needed it most. I hope that you have a year full of happiness and blessings. Oh! I forgot, you already have me, the best blessing ever haha. We don’t agree with almost everything( extremes meet, right?) but the fact is, we couldn’t have been without each other, and that says a lot. You’ve always had my back and I don’t think I could have survived so many negative situations without you by my side. You know things about me, that no one else on Earth does. You probably know me better than I do, and that is so rare nowadays.

I Love you, and the way we’re always back to being together even after long fights and periods of being apart, and how I feel so home with when you are around. So many tears, jokes, memories and laughter, fights and dreams we’ve been through, it is all so priceless for me. Thanks for always giving me a gentle reality check when I needed it or deserved it and for giving me a helping hand whenever it was obvious I couldn’t have made it through without you.

A friend you can’t live without


Just modify this letter so it suits your situation, and there you have it, a touching letter for your best friend’s birthday.


Drear friend,

Today is your birthday, and I don’t even know where to begin. There are so many things I’d love to tell you on your special occasion that I literally could not fit into this very letter. So let me begin by saying the most obvious of all things: You’re my best friend, and you mean so much to me.

Since the moment you appeared in my life, we got along like a house on fire. You were like the perfect piece to my that completes my puzzle. Not that anything was missing in the first place, but you became an essential part of me and you made me way better than I was before you. I know you’re probably laughing right now thinking this is super cheesy. Yeah, kinda, but I can’t help it.

One thing that does not cease to amaze me is your unconditional form of giving to others. Anytime I need something, you never hesitate to offer it to me, no matter what it is and even more. If I happen to have a bad day, you listen attentively to my problems( sometimes serious, sometimes not) and you reassure me that it will all pass sooner than later. And the moment I need your shoulder to cry on, you never hesitate to return me right into reality and tell me to stay strong. You give me so much strength you won’t believe it and you’ve taught me to make this my lifestyle no matter what’s going on in my life.

I guess what I want to say is that I am so thankful for having you in my life. Especially on a day like today, we celebrate your life and wish you so many more years to walk this crazy world and sprinkle a little bit of happiness into everyone’s life. Thank you for being you, dear. You are a very special person. Happy birthday, special girl. You’ve changed my life and you inspire me every day, I hope I can return you some of those great favors one day when you need it the most.


Your Best Friend Forever

Dear You,

Today is your very special day, but I also have a reason for celebration. Today is the day my soulmate, my biggest strength in life, my shoulder to cry on, and my missing piece of the puzzle that completes me was brought into this wild world. Today is your birthday.

Even though I don’t really need a special occasion like this to realize that I couldn’t quite imagine my life without you by my side, this is the day that I simply have to tell you how much you, my dear friend, mean to me, and how much I cherish every day spent with you. 

And that is exactly the reason why I am writing this birthday letter for you – to wish you all the best in the world and remind you that I love you very much, even though I don’t say it as often as I should really.

Today is the day I think about all of our fantastic memories, all the milestones and obstacles we defeated being together, and all those happy and sad moments we have experienced side by side. I remember our long late-night phone calls, all of our secret drunk parties, all of our very serious talks, and all the fun we’ve had through the years together. I remember the day I met you and the day my life changed for the better, all thanks to you.

They say that everyone enters our lives for a specific reason. And since I met you, I’ve realized that this is nothing but the very truth, because fate had to have a reason to send you to me when I needed you the most.

From day one, you’ve acted like my big sister I have never had and I had no choice but to let you in. You took care of me so well and you pushed me forward so I could achieve my goals. Before I knew it, you became my greatest source of inspiration and the only person who believed in me no matter what, even in the situations when everyone else was ready to give up on me. The person who saw the good side in me when I was at my rock bottom and the one who had faith that I was destined for greater things.

You deserve the world of blessings, but I’ll wish you nothing less than loads of happiness, love, and health. And most of all – I wish for you to always remain the perfect person you are today.

Here is to another year of joy, laughter, new memories, and pure happiness that I was fortunate to spend with you. Here is to another year of you being you. Happy birthday, my friend. 


1. I feel so lucky to have you as my best friend. I hope your birthday is as special as you are to me, dear. May all of your dreams come true, even the craziest of them. Thanks for always being such a great friend.

2. Birthdays inevitably come around every year, but true friends like you only come once in a lifetime. I’m so truly grateful you came into my life. Best wishes on your very special day my friend.

3. This is my wish for you, my best friend: I hope you never stop enjoying the small things in life just like you do now, because that’s what really makes life worth living. I hope you take the time to enjoy your present while working for a better future and manage to keep the balance between them. I hope your year is full of memories, health, happiness, and adventure.

4. I am so looking forward to many more years of friendship and birthdays with you, my best friend. Have a fantastic birthday and a great year!

5. I am grateful for your true friendship, it is a pure pleasure to have you as a friend. I hope your birthday is as amazing as you are my best friend forever!

6. You’re older than you’ve been, old lady haha. But look on the bright side of it, you’re younger now than you’ll ever be, think about it and have a wonderful birthday!

7. Today I want to wish you all the love and happiness in the world, all of which you truly deserve. Happy birthday, my best friend!

8. I can promise that the more birthday candles you blow out, the more I will be here for you to celebrate every special event in your life, have a great year, look forward to spending it with you.

9. I hope your birthday is as sweet as your birthday cake, and the year to follow is filled with as much joy as you bring your friends every single day!

10. I am so grateful that you are a part of my life, you make every day so special for me. All the best on your birthday, dear!
