Bold fonts for Instagram

The generator has four bold styles. They look different, and only two of them make numbers bold, which matters whenever a caption is about a price, a date or how many places are left. Here is “Only 3 spots left” in each.

Unicode drew bold digits for the upright styles only, so in bold italic and bold cursive the 3 stays a regular, thin 3. If the number is the news, use plain Bold, which also sits closest to the lettering Instagram itself uses.

The pattern holds everywhere: bold marks where to look, and the plain words around it say what you mean. A post where everything is bold gives the eye nowhere to land first.

On a Reel, the caption sits over the bottom of the video and only its first words show until someone taps it. A bold opener there gets read while the video plays, so make it the label for the whole Reel, such as 𝗣𝗮𝗿𝘁 𝟮 or 𝗦𝘁𝗲𝗽 𝟭, and put the explanation after it in plain text. Words you want on the video itself belong in the Reels editor’s text tool, which has fonts of its own.

A carousel has one caption for every slide, so readers have to match the text to the pictures themselves. Bold slide labels do that job: 𝗦𝗹𝗶𝗱𝗲 𝟭 for the raw clay, 𝗦𝗹𝗶𝗱𝗲 𝟮 for the shaped bowl, and so on. Use the Bold style rather than bold italic, so the numbers in the labels come out bold too.

Tip: Write the labels in the same order as the slides, and check them again if you rearrange the slides before posting.

Bold letters are characters with identities of their own, and three things on Instagram notice the difference.

• Search: Instagram has said it matches what people type against usernames, bios, captions, hashtags and places. People type plain letters, so a word that appears only as 𝗰𝗲𝗿𝗮𝗺𝗶𝗰𝘀 may not be found by someone looking for ceramics. Bold the hook and leave the topic words plain.
• Listening: screen readers may read each bold letter by its full Unicode name, spell the word out or skip it. A bold first line with plain sentences after it keeps the post usable for someone listening.
• Copying: a bold price or class time copies as maths characters, which a calculator or a booking form may not accept as numbers.

None of this is a reason to avoid bold, only a reason to keep it short. A few bold words on a post cost almost nothing; a bold caption from top to bottom costs all three.
