Frequently Asked Questions
What is the hook zone?
The hook zone is the first three lines of your post — the text most people see before tapping "see more" on X, LinkedIn, Instagram, or Facebook. Strong hooks belong in those lines.
What are the character limits for each platform?
X allows 280 characters per post. LinkedIn allows 3,000 characters. Instagram captions allow 2,200 characters. Facebook posts allow up to 63,206 characters.
Do emojis count as characters?
Yes. Emojis and special characters count toward the limit. Some emojis use multiple code units, so the count may differ slightly from what a platform shows internally.
How is this different from the Hook Analyzer?
The Hook Analyzer scores your opening line for curiosity and power words. This tool focuses on character limits and hook zone visibility across social platforms.
Is my text stored or sent anywhere?
No. All counting runs entirely in your browser. Your post never leaves your device.
Is this tool free and does it work on mobile?
Yes on both counts. The Social Media Hook & Character Counter on draft21 is completely free with no sign-up required and works on all devices.
