Character limits of popular platforms
Before you post, it helps to know how much text a platform accepts. The table lists limits published by the platforms themselves. Checked on 7 November 2026. Platforms can change their limits at any time, so follow the source link if you are close to the maximum.
| Platform and field | Limit | Official source |
|---|---|---|
| X (Twitter): standard post | 280 characters (X weights some characters, such as emoji and links, differently) | X Developer Platform: Counting characters |
| Instagram: caption | 2,200 characters, 30 hashtags, 20 @ tags | Meta for Developers: IG User Media |
| LinkedIn: post | 3,000 characters | LinkedIn Help: posts and articles |
| LinkedIn: article | 125,000 characters | LinkedIn Help: posts and articles |
| YouTube: video title | 100 characters | YouTube Help: Edit video settings |
| YouTube: video description | 5,000 characters | YouTube Help: Edit video settings |
Platforms without a clearly published limit that we could verify on the check date are not listed. We do not estimate limits.
Do spaces count?
The sources above state limits in characters and do not list spaces, line breaks or emoji as exceptions. To be safe, count everything you type. WordCounter.Cloud shows characters with and without spaces, so you can see the full length at a glance.
How to check your text
Paste or type your text on the WordCounter.Cloud start page. Your text is processed locally in your browser. Compare the character count with the limit of the platform and shorten your text if needed. On X, the platform's own count can differ slightly because of its weighting rules.
