What Font Does X (Twitter) Use? Meet "Chirp"
X's brand font is called Chirp, a custom grotesque sans-serif introduced in 2021. But what renders your bio and posts depends on where you're reading. Here's the honest breakdown.
What Font Does TikTok Use?
TikTok's brand typeface is TikTok Sans, introduced in 2023 to replace Proxima Nova. But that's different from the caption styles in the video editor and the system font that renders your bio. Here's how all three fit together.
What Font Does Instagram Use? (Brand, App & Stories Fonts Explained)
Instagram uses three different type layers: Instagram Sans for its brand and marketing, your phone's system font (SF Pro or Roboto) for bios and captions, and five preset styles in Stories. Here's exactly what each one is.
Facebook Comment Character Limit (2026): The Real Number
Facebook doesn't publish an official comment character limit, but testing shows comments cut off around 8,000 characters. Here's the full 2026 Facebook spec — comments, profile bio (101), Page bio (255), and username (5-50) — plus which numbers are firm and which are soft.
Twitch Character Limits: Chat, Stream Title, Bio & Panels
Twitch caps a chat message at 500 characters and a stream title at 140. This is the field-by-field reference: chat, whispers, stream title, bio/About, and panel limits, plus the two real bot limits over IRC (a ~469-character full protocol line and a 50-character cap on unmodded bots) and how emoji and pasted Unicode inflate the count.
Pinterest Character Limit
Every Pinterest character limit in one place: pin title 100, pin description 500, board name 50, board description 500, username 30, and profile bio up to 500 characters — plus the widely-repeated "bio 160" figure that's now out of date. Verified against Pinterest's own help center and API v5.
Snapchat Character Limit
Snapchat's only officially documented character limits are a 3–15-character username and a 30-character display name (including spaces). The snap caption has no published cap — roughly 80 characters fit on one line, but you can enlarge the text and stack boxes to fit far more. Here are the verified 2026 numbers, plus the myths (like "50 characters" and "usernames can't be changed") that third-party trackers still get wrong.
The Tumblr Character Limit: Asks, Bio, Tags & Posts (2026)
Tumblr doesn't have one character limit — it has a different cap for almost every field. Asks stop at 500 characters, your blog description at 2,000, each tag at 140, and a single text block in a post at 4,096. This is the verified, field-by-field breakdown for 2026, sourced from Tumblr's own changelog, Help Center and NPF spec — including the counting quirks (emoji, graphemes) that make the numbers behave oddly.
Reddit Character Limit: Titles, Posts, Comments & Bio (2026)
Reddit post titles cap at 300 characters, text posts at 40,000, and comments at 10,000. Here is every Reddit character limit for 2026 — username, display name, bio, flair, and subreddit fields — in one spec table, with the nuances that trip people up.

Craft notes on writing for the internet. One short email, every other week. No spam.
BoldlyType is a free Unicode text formatter, and this blog is the part where we explain ourselves. It's a working notebook on writing for the internet: how text actually renders in the plain boxes you post into, how to format when the platform gives you no toolbar, and how to write captions, bios, and hooks that earn attention without sounding like a brand intern. Most of the answers here came from breaking things across LinkedIn, Instagram, Threads, WhatsApp, and Discord first, then writing down what survived. If you write in a box that only takes plain text, this is for you.
What this blog actually covers
Six topics, organized as pillars. Each one is a hub that collects every related guide in one place, so you can read down a single thread instead of hunting through the archive. A post usually does one of three jobs: it answers a specific question you'd type into a search bar ("how do I bold text on LinkedIn"), it teaches a writing skill (a hook formula, a bio structure), or it tells you the truth about a formatting trick before you lean on it.
The throughline is that formatting and writing aren't separate problems. A bold-text generator is useless if the words next to it are boring, and the best caption in the world dies if the line breaks collapse on mobile. We cover both halves because you need both halves.
Fonts & Fancy Text
The "how does this even work" pillar. Unicode "fonts" aren't real fonts — they're math-alphabet look-alike characters that your phone treats as bold or italic. This is where we explain what those styles are, why they sometimes show up as empty boxes on someone else's screen, and which ones travel well across platforms. If you've ever copied a fancy font and watched it break in someone's DMs, start here.
Pairs with the formatters at /text-generator, /bold-text-generator, and /italic-text-generator.
Platform Formatting How-Tos
Step-by-step recipes for platforms that don't give you a formatting toolbar. Bold and italic on LinkedIn, line breaks that don't collapse on Instagram, bullet points in a bio, monospace in Discord, structure in a WhatsApp broadcast. Each guide is the literal sequence of steps, not a lecture about why formatting matters.
Pairs with /linkedin-text-formatter, /instagram-text-formatter, and the rest of the tool pages.
Personal Branding
Personal branding is a writing problem before it's a design problem. This pillar covers the craft underneath a profile people actually follow: headlines, the first line of a post, bio architecture, and the unglamorous discipline of showing up consistently. No "build your empire" energy — just the sentences that do the work.
Aimed at anyone growing an audience under their own name: founders, freelancers, job-seekers, creators.
GenZ & Internet Writing
How to write in a voice that reads as genuinely online instead of a 38-year-old's impression of one. The lowercase aesthetic, when slang lands and when it's cringe, emoji used as punctuation, tone calibration per platform. The goal is fluency, not a costume — and knowing the difference is most of the skill.
Useful for brands trying not to sound like a brand, and for anyone whose audience can smell try-hard from three words in.
Captions, Hooks & Hashtags
The practical craft of the things that move the needle: scroll-stopping first lines, captions that hold a reader past the "…more" fold, hashtag strategy that isn't superstition, and bios that convert a profile visit into a follow. Formulas you can reuse, with examples, not vibes.
Pairs with the generators in /tools when you want to draft fast and refine.
Accessibility & Safe Formatting
The pillar where we tell you what the formatting tricks cost. Unicode bold and italic are look-alike characters, which means screen readers often mangle them — reading "𝗯𝗼𝗹𝗱" as a string of unrelated symbol names, or skipping it entirely. Search engines and some platform algorithms don't always parse it as text either.
Our rule, repeated across these posts: use fancy formatting for emphasis and flourish, never for essential information. Your name, your call to action, your one important link — keep those in plain text. This pillar gives you the honest map of when a trick is harmless and when it quietly excludes part of your audience.
Who it's for, and where we stand
This is for creators, marketers, community managers, job-seekers, and anyone typing into a plain-text box that won't let them bold a single word. You don't need to be technical. You need to make text look intentional and read well in places that weren't designed to help you.
Editorially, two commitments. First, we're honest about Unicode's accessibility trade-offs even though our own tools generate it — the formatter is great for emphasis and bad for anything a screen reader needs to read aloud, and we'll keep saying so. Second, no growth-hack snake oil. No magic posting times, no engagement-pod gospel, no "this one trick." If something only works because an algorithm is having a weird week, it doesn't go in the blog. Everything here is curated and edited by Shreyas Bagal, who has spent the better part of a decade obsessing over how text renders across platforms — which is a strange thing to care about, and exactly why this site exists.
