Personalizing Your Sister Captions

There are a lot of captions in the list above. You can easily pick and choose the best one, paste it into Instagram, add your photo, and hit publish.

However, sometimes you want to make your caption even more personalized.

Whether you want to stand out for a special occasion or just share the love, here are the best ways to make the above captions yours.

Answer Specific Questions

Here’s a list of quick questions to consider when personalizing your captions. Don’t overthink the answers:

  • What’s a specific sister memory related to the photo you’re about to publish?
  • If you could only describe your sister using one word or phrase (in the photo or otherwise), what would that be?
  • How did your sister make you feel as you took the photo / were sharing the experience?
  • What’s something unique or special about your relationship with your sister?

Answering these questions (and relating the answer to the photo/video you’re posting) will help you develop a unique caption.

Combine the answers with one (or more) of the captions above, and you’ll have a truly unique caption. You’ll also ensure you come up with a different caption each time.

Use These Fill-In-The-Blank Templates

Want even more ideas to help you craft the right sister captions for Instagram? Here are fill-in-the-blank templates you can use.

Simply swap the phrases in brackets with something highly relevant to the relationship you have with your sister:
