Instagram Bio Character Limit (2026 Update)
The Instagram bio character limit is 150 characters. That includes every letter, number, space, and emoji. In 2026, Instagram still uses this limit for the main bio field, so fitting your message—and often a link or call-to-action—requires careful counting. A free Instagram bio character counter like this one helps you stay within the limit before you hit save. This tool uses grapheme-aware counting so emojis and special characters (including skin tone modifiers and ZWJ sequences) count correctly, matching how Instagram measures your bio. No login, no account, and your text is only stored locally in your browser if you use the auto-save feature. You can trim to fit, get a suggested shortened version, and copy your bio in one click.
Twitter/X Bio Length Limit
Twitter (X) bio length is 160 characters. Your name and bio together define your profile on X, and the bio field alone is capped at 160 characters. Many users run over the limit without realizing it and end up with a truncated bio. Use this bio character counter to check your length before updating your profile. The tool shows characters, characters without spaces, word count, line count, emoji count, and average word length so you get a full picture of your text. You can also see how your bio fits each platform in one place—Instagram, X, TikTok, LinkedIn, and Facebook—and copy your bio with one click when it's ready. The progress bar uses color coding: green under 70% of the limit, amber from 70% to 90%, orange from 90% to 100%, and red when over.
TikTok Bio Character Limit
The TikTok bio character limit is 80 characters—one of the shortest limits among major platforms. That makes every character valuable. A good TikTok bio often includes a hook, your niche, and maybe an emoji or two. This counter helps you stay within 80 characters while showing you how the same bio would fit on Instagram (150), X (160), LinkedIn (2,600), and Facebook (101). When you're over the limit, you can use "Trim to TikTok limit" to cut at a grapheme boundary so you never split an emoji. The "Suggest shortened" option collapses extra spaces, removes duplicate words, and trims repeated emojis—all in your browser with no server. No signup and no data sent to any server; everything runs locally.
LinkedIn Bio About Section Limit
LinkedIn allows up to 2,600 characters in your About (summary) section. That's enough for a full professional summary, so most users don't hit the limit. Still, knowing your character count helps you plan structure and avoid accidental truncation. This tool shows your current count and how much space you have left for each platform. If you write one bio and reuse it (shortened) on Instagram or TikTok, you can paste it here, see the counts for all platforms, trim to fit a specific limit, or optimize the text.

Facebook Bio Character Limit
Facebook page bios display about 101 characters above the fold. Keeping your key message within that length helps visitors see the most important info without clicking. This tool checks your count across Instagram, X, TikTok, LinkedIn, and Facebook in one place. Switch between platform tabs to see the limit, remaining characters, and a tip for each. On mobile, a sticky summary bar at the bottom shows the active platform and a mini progress bar so you always know where you stand. All counting is grapheme-based so emojis and combined characters (e.g. flags, skin tones) count as one character, matching how these platforms typically enforce limits.
Why Accurate Emoji Counting Matters
Many basic counters use .length, which counts UTF-16 code units. A single emoji or a character with a modifier (e.g. skin tone) can be two or more code units, so your count gets inflated and you might trim content that was actually under the limit. Grapheme-aware counting uses Intl.Segmenter (when available) or Array.from so that each visible character—including ZWJ emojis, flags, and skin tone modifiers—counts as one. That matches how Instagram, X, TikTok, and others typically measure and truncate bios. This tool also shows an emoji count so you know how many of your characters are emojis. Accurate counting avoids surprises when you paste your bio into the platform and find it cut off or rejected.
How to Write a High-Converting Bio
A high-converting bio is clear, benefit-focused, and within the platform limit. Start with who you are or what you offer in one short line. Add a clear call-to-action (e.g. "Link below", "DM for…") or your main keyword. Use line breaks sparingly on Instagram (they count as one character each) to improve readability. Check your character count as you write: this tool shows characters remaining so you know how much room you have. If you're over, use "Trim to [Platform] limit" to cut at a safe boundary, or "Suggest shortened" to preview and apply optimizations. Then copy your bio and paste it into the platform.

Examples of Great Bios
Strong Instagram bios often follow a simple pattern: one line for identity, one for value, and a call-to-action. For example: "Content creator · Helping you grow · Link below" stays under 150 characters and is easy to scan. X (Twitter) bios can be punchier: "Building in public. SaaS founder. Tweets on product & growth." TikTok bios need to hook in 80 characters: "Day job: marketing. Side hustle: this. 👇" LinkedIn About sections can use the full 2,600 characters for a narrative—start with a hook, then experience, then what you offer. Use this bio character counter to check each platform before you publish. Pair your bio with the right hashtags and a well-formatted caption for a complete profile.
Why Emoji-Safe Counting Matters
When your bio includes emojis, skin tones, or special characters, simple .length counts can be wrong. Emoji-safe (grapheme-aware) counting ensures each visible character counts as one, so you never trim in the middle of an emoji or get rejected by the platform. This tool's "Simulate platform counting" option uses the same logic most platforms use. Turn it off to compare with raw character length.

Why Bio Length Matters
Each platform truncates bios that exceed the limit. On Instagram, a bio over 150 characters gets cut off with an ellipsis, and visitors may not click to see more. On X, you simply can't save more than 160 characters. On TikTok, 80 characters is all you get. Writing within the limit the first time improves clarity and ensures your full message is visible. A private, instant character checker that works for Instagram, TikTok, LinkedIn, and more—without login or signup—makes it easy to stay within limits. This tool shows "characters remaining" or "characters over" in large type for the active platform, plus a progress bar and an "All platforms" summary.

Common Bio Mistakes to Avoid
Going over the character limit is one of the most common bio mistakes. Always check your count before saving: use this bio character counter to see exactly how many characters you have for Instagram (150), X (160), TikTok (80), LinkedIn (2,600), and Facebook (101). Another mistake is stuffing too many emojis—readability drops and some platforms treat emojis differently. Keep a balance and use the emoji count here to stay aware. Writing a single block of text with no line breaks can make an Instagram bio hard to scan; use line breaks sparingly (each counts as one character). Avoid vague phrases like "Follow for more" without saying what you offer. Finally, don't forget to include a call-to-action or link when you have room—the best bios tell visitors what to do next. Use "Trim to limit" and "Suggest shortened" to stay within limits without losing your message, and explore our social media tools for hashtags and caption formatting.
