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.

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.

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:

• Supportive: Happy birthday to the most amazing person I know! I love you [a word/phrase for a huge amount] and can’t wait to celebrate your big day with you, [sister’s name]!
• Adventurous: “Here’s to climbing new heights with my forever adventure pal, [sister’s name]! Can’t wait to tackle our next big dream: [shared dream/goal].”
• Funny: Remember when we wore those [type of clothes] that were way [something quirky about the clothes]? We thought we looked so [adjective]. But looking back, it’s one of our funniest [type of moment]. It’s a great example of our epic journey together.
• Supportive: I want to say a big thank you. You’ve always had my back, even when I [negative emotion]. That means a lot. You’re like the best cheerleader ever! Remember when you supported me during [specific time]?

The above templates allow you to focus on the special memories and bonds you share with your sister without having to search for the right words.

Even if you’re pretty alike, your sister has her unique traits. It’s important to mention these traits in the captions you create.

It shows your thoughtful side and that you see your sister as an individual.

Whether you admire your sister for her unlimited courage, sarcasm, kindness (or a mix of all), find ways to mention this.

You don’t have to go into much detail (though it’s great if you can) – a brief mention can do the trick.

Nicknames and inside jokes fall within this type of caption. Adding a layer of intimacy deepens any relationship – and the one with your sister is no different.

Just because it’s Instagram doesn’t mean you should ONLY show the positive side.

Expressing genuine feelings (both highs and lows) is essential. Your emotion will shine through the words you use when you’re authentic.

When coming up with sister captions, it’s also important not to force it. You don’t have to find the perfect caption before posting your photo.

If you’re feeling uninspired, don’t hit publish at that moment. Take a break. Go for a walk and do something different. Sometimes, the best ideas come when we’re not actively thinking about them.

The proper captions for Instagram offer a beautiful window into the bond between sisters.

The unique, cherished, and chaotic nature of sisterhood deserves to be captured in the perfect caption.

By choosing the right captions and making them unique (following the tips I gave you), you’ll have the right ingredients for powerful Instagram posts.

Combine that with the right image, and you’ll stand out on this social platform.
