Mark your calendars! Father's Day is coming up. While you may have the perfect gift for your father-in-law already picked out, the happy Father's Day message for your father-in-law is just as important. He's the dad of your partner and helped raise them into the loveable person they are today, which more than earns him a shout out. If you're feeling the pressure or need some inspiration to get you started, we've compiled a list of messages you can write in his holiday card, ranging from goofy to sentimental. Whether he's your future FIL or you've been part of the family for years, take a look at our sample notes below to learn how to write the best Father's Day wishes for your father-in-law.

What to Write in Your FIL's Father's Day Card

Here are a few things to consider if you're wondering what to write in your father-in-law's Father's Day card: Before putting your pen to paper (or in this case, cardstock) to compose your Father's Day greeting for your father-in-law, think about your relationship with your FIL. This will help determine how sentimental you should be when crafting your message. If you're still getting to know him, then noting a characteristic or two you admire is a great place to start—especially if you're feeling unsure. Now, if you've known him for years, then calling out a favorite memory or delving into how much you appreciate and treasure your relationship is okay to call out.

You should also take into account his personality while planning out your happy Father's Day message. If he is someone who is always cracking dad jokes or loves a good pun, you should definitely include a funny message. Now, if he's always going in for a hug when he sees you and your partner or loves to get nostalgic with stories of your boo as a child, then a heartfelt line or two is a must. Don't forget to call out how much you appreciate all that they do for the family and end the card on a sweet note to make him feel loved and appreciated. If you take all of these elements into consideration, it'll be almost impossible for your father-in-law not to keep this card on display year-round. You'll be an expert on what to write to a father-in-law on Father's Day in no time.

Funny Father's Day Messages for Your FIL

There's nothing like a silly note to keep things lighthearted—especially if your FIL appreciates a good pun. If he's the first to make a dad joke, tickle his funny bone with a goofy message that'll have him laughing out loud. Just don't be surprised when he starts cracking jokes back after your father-in-law reads your funny happy Father's Day message.

  • I'll try not to make this too cheesy, but I hope you have a gouda Father's Day—from your favorite [son/daughter/child]-in-law.
