Twitter / X Character Limits

Twitter/X has the tightest character limits of any major platform, which is both a constraint and a creative challenge. Here's every limit you need to know:

𝕏

Twitter / X

Tweet text280 chars

Tweet (Premium)25,000 chars

Bio160 chars

Display name50 chars

Website URL100 chars

Direct message10,000 chars

💡 Twitter/X Pro Tips

URLs are always counted as 23 characters regardless of their actual length. Images, videos, and GIFs don't count toward your character limit. X Premium subscribers get 25,000 character long-form posts.

Instagram Character Limits

Instagram

Caption2,200 chars

Visible before "more"~125 chars

Bio150 chars

Username30 chars

Hashtags per post30 max

Story text~220 chars

Reels title55 chars

Instagram captions can be up to 2,200 characters, but only the first ~125 characters are shown before the "more" truncation. This makes your caption hook critical — front-load your most important information.

Writing Within Character Limits: Expert Tips

✂️

Front-load your hook

Put your most compelling line first. Most platforms truncate captions after 125–477 characters, so make those first words count.

🔗

Use URL shorteners

On Twitter/X, all URLs count as 23 characters automatically. On other platforms, short URLs save characters and look cleaner.

📝

Write long, then edit down

Write everything you want to say first, then cut ruthlessly. Every word should earn its place. Aim for 80% of the character limit.

🧵

Use threads for long content

Twitter threads, LinkedIn articles, and Facebook Notes let you go deeper without squeezing everything into one post.

👁

Preview before publishing

Use PostPreview to see exactly how your caption will be truncated on each platform before you hit post. Saves time and embarrassment.

🎯

One message, one post

The tighter the character limit, the more focused your message needs to be. Trying to say two things in 280 characters never works well.

🔢
