Instagram Bio Generator (FREE TOOL)

Glossier opens its bio with a four word promise: "Skin first. Makeup second." It says what the brand believes and what it sells in one breath, with nothing to skip.

Bombas puts its giving model in the bio, one purchased and one donated, and a hashtag buyers can tag, #BombasInTheWild. The bio sells a reason to buy along with the socks.

OLIPOP fits the product and its two numbers into one line: "The feel good soda", two emoji, then "High fiber, 5g or less sugar". A reader knows what it is and why it is different before they tap.

Liquid Death leans on its own hashtags, #MurderYourThirst and #DeathToPlasticBottles, so the bio carries the joke and the mission at once.

What the four share: the first words say what the brand is, there is one reason to care, and there is no filler. We read these bios on 26 October 2026 from each brand's Instagram listing, as Instagram's own page showed in search. Bios change, so open the profile for today's version.

Every letter, space, emoji and line break counts. A line break is one character, so a four line bio spends 3 of its 150 on breaks.

Emoji are where character counts disagree. This tool counts each emoji as 2 characters, the stricter way, so a bio it shows at 150 always fits when you paste it.

Your links do not count: they live in the Links field, up to 5 of them. Your name and your @username are separate fields too, so the bio can spend all 150 characters on what you sell.

Last checked: 26 October 2026. The 150 character limit comes from Instagram's help page on bios, and the 5 links from its page on websites.

• Ten fit cases were worked by hand: a bio under the limit, exactly 150, one line past it cut on a whole word, a three line bio losing its last line, emoji counted as 2 and never cut in half, a comma left at the end, a line with a link, an em dash, blank lines and markdown. The code agrees with every one.
• When a bio comes back over 150, the code asks the model once more, then cuts any bio still over. A test sends a 221 character bio and checks that it comes back at 150 or fewer, on a whole word.
• The code removes any @ handle or hashtag you did not type, so no account or campaign is made up.
• Typical, boundary and hostile inputs ran through the real page with the model reply stubbed: an empty form, a one word description, a non-English description and an instruction typed into the description box.
• The eight profiles above carry bios written from each ad's own words and checked by the same code the tool runs.
