Frequently asked questions

What is a good caption for a best friend?

A good best friend caption is short and sounds like the two of you. Inside jokes work well, as do simple lines like “Me and my person” or “Partners in crime since day one.” If in doubt, keep it warm and let the photo do the rest.

How do you write a short caption for your best friend?

Pick one idea and say it in five words or fewer: who they are to you, a shared joke, or how long you've been friends. “Day ones only” and “Same brain, different face” are good examples.

What should I caption a throwback photo with my best friend?

Lean into the time that has passed. Captions like “Old pics, golden memories” or “Proof that we've been chaotic since day one” work for any old photo of the two of you.

What can I give my best friend instead of just a post?

Print your favourite photos together. A photo book of your friendship, a set of Instagram-style prints or a photo puzzle are personal gifts that last far longer than a post.

Celebrate your friendship beyond the feed

Start with a softcover photo book of your friendship, or print your best shots as Insta cards to stick on the fridge.
