While Instagram allows you to use nine different fonts in your stories, you are stuck with a single boring sans serif for your profile information, regular post text and comments. This is how you can limit the restrictions and spice things up.
How custom Instagram fonts work
Instagram uses the Proxima Nova font for small text such as comments and captions. There is no way to change it, but you can get around it.
To work with different alphabets, punctuation, scripts and emoji, Instagram also supports most Unicode scripts. Although these include things like mathematical operators (÷), Greek symbols used in science (Ω) and Hebrew letters (a), they also include some basic letters, such as 𝒶 𝒽𝒶𝓃𝒹𝓌𝓇𝒾𝓉𝓉𝑒𝓃 𝓈𝒸𝓇𝒾𝓅𝓉, 𝔞 𝔊𝔬𝔱𝔥𝔦𝔠 𝔰𝔱𝔶𝔩𝔢 and ⓛⓔⓣⓣ Ⓔⓡ Ⓒⓘⓡⓒⓛⓔⓢ ⓘⓝ ⓒⓘⓡⓒⓛⓔⓢ. Different characters can even be combined to do things like an up and down font (ʇuoɟ uʍop ǝpısdn uɐ) and ฬ ђ ค Շ є sh єг ts ๏ ย ς ค ɭɭ Շ ђ เร.
(It should be clear that How-To Geek also supports Unicode!)
So now that you know what’s going on, let’s look at how to easily use these fake fonts on Instagram.
How to add scratchy fonts to your captions and biographies
While some Unicode characters can be typed using a standard keyboard, copying and pasting from an app is easier if you want to do more than replace a + sign with a “t”.
Go to CoolFont.org on your smartphone and enter your caption or comment. It gives you about 100 different text options, ranging from cool to barely readable. Press the “Decorate” button to add additional text decorations such as hearts, stars, and random patterns.
When you are satisfied with the text, select it and press “Copy” or just press the “Copy” button. You can then paste it into any text field on Instagram.
It will even work with Instagram stories, but it probably does not look as good as the built-in options.
You can use the same technology to add fun fonts to other social media sites that support Unicode like Twitter and Facebook. Just be careful: you want to make sure that everything you write is still easy to read.
