Character counter online

How to use the character counter

1. Paste or type your text into the box.
2. Check the character count with spaces against your platform's limit.
3. Check the count without spaces if your limit specifically excludes spaces.
4. Check the byte count if you're working with a byte-based limit (common in SMS and some databases).
5. Trim your text and recheck until it fits.

Most social platforms and form fields count characters including spaces; a byte-based limit (common for SMS) can differ from the character count when your text includes non-ASCII characters like emoji or accented letters.

What this counts and how it works

Characters with spaces is simply the length of your text, counting every character including spaces and punctuation. Characters without spaces strips whitespace before counting. The byte count encodes your text as UTF-8 and counts the resulting bytes — for plain English text this usually matches the character count, but emoji, accented letters, and non-Latin scripts can each take 2-4 bytes per character, so the byte count can be noticeably higher than the character count for that kind of text.

Best practices

• Know whether your limit counts spaces. Most do, but some legacy systems and specific fields don't; check the exact wording of the limit.
• Check byte count for SMS and legacy systems. SMS messages are traditionally limited by byte count (140 bytes per segment in many encodings), not character count, which matters if your message includes emoji or accented characters.
• Leave margin for platform-added text. Some platforms append a link or signature to your text automatically, which counts against the same limit.

Common mistakes to avoid

• Assuming character count and byte count are always the same. They diverge as soon as your text includes emoji, accented letters, or non-Latin scripts.
• Forgetting that URLs and mentions count toward some platform limits even when the platform displays them shortened.
• Not rechecking after emoji edits. A single emoji can use 2-4 characters/bytes depending on the platform's counting method, which adds up quickly in a short-form post.

Real-world use cases

• Social media posts with a hard character cap.
• Meta descriptions and SEO titles, which search engines truncate past a certain character count.
• SMS and notification text, where byte count affects message segmentation and cost.
• Form fields (bios, product names, usernames) with a stated maximum character length.

Limitations

This tool counts raw characters and UTF-8 bytes; it does not know a specific platform's exact counting rules (some platforms count certain emoji or combined characters differently than a simple length calculation). For platform-specific limits, treat this as a close estimate and verify against the platform's own counter if one is provided at the point of posting.

Privacy

Text you paste into this counter is processed locally in your browser as you type. It is not sent to a server, logged, or stored. See the privacy policy for the site's full data handling approach.

Troubleshooting

• If your byte count is higher than expected, check for emoji or accented characters, which use more than one byte each in UTF-8.
• If a platform rejects your text despite fitting this count, double-check whether that platform adds extra characters automatically (like a link or hashtag).
• If you need a word-based limit instead, use the word counter.

Conclusion

Use the character counter for any platform or form with a strict character or byte limit — tweets, meta descriptions, SMS, and short form fields. For word-based limits, use the word counter instead.
