Check limits for social posts, forms, assignments, or database fields. Counts update as you type or paste. Your content stays in the browser—it is not uploaded to Webooro.
Limits change from time to time, so check the platform itself before you rely on a number.
| Where | Limit | Note |
|---|---|---|
| X (Twitter) post | 280 characters | Korean, Chinese and Japanese characters count as 2, so about 140 of them fit. |
| Instagram caption | 2,200 characters | Only the first lines show before "more", so put the key point first. |
| YouTube title / description | 100 / 5,000 characters | Long titles get cut off in search results and on mobile. |
| Korean SMS / LMS | 90 bytes / 2,000 bytes | Carriers count a Korean character as 2 bytes, so an SMS holds about 45 Korean characters. |
Why the byte count here may not match a text message: this counter measures bytes in UTF-8, the encoding used on the web, where one Korean character is 3 bytes. Korean carriers use a 2-byte encoding for SMS, so for text messages divide the Korean part by 3 and multiply by 2 — or simply keep Korean messages under about 45 characters.
Your text is processed only in the browser and is not sent to our servers.
Korean text, emoji, and mixed scripts can use many more bytes than “characters” in UTF-8. Some services limit by bytes, not glyphs—so we show both.
Word count splits on whitespace; it is a simple heuristic. English is closer to “words”; Korean phrases may not match every app’s definition—use as a rough guide.
Useful for Twitter/X limits, blog titles, product name fields, VARCHAR sizes, and draft length checks.
Word processors also count text, but this page is fast when you only have a browser. Nothing is uploaded to our servers.
Each platform defines “character” differently (emoji, spaces)—always double-check in the target app before final submit.
