Social Media Character Counter

Twitter (X) allows 280 characters per tweet. Links are automatically shortened to 23 characters by Twitter's t.co shortener, regardless of the actual URL length. Images, videos, and polls don't count toward your character limit.

Instagram captions allow up to 2,200 characters, but only about 125 characters (roughly two lines) are visible before the "...more" tap. Put your hook and most important information in the first two lines. Instagram bios are capped at 150 characters.

Facebook allows up to 63,206 characters, but shorter posts get more engagement. Posts of 40–80 characters perform best in terms of reactions and shares. If you have more to say, a short hook in the post with a link to the full content often works better than a wall of text.

Twitter: 1–2 hashtags. More than that tends to hurt engagement. Instagram: 3–5 works better than 20–30 for most accounts. LinkedIn: 3–5 relevant hashtags. TikTok: 3–5 hashtags. Facebook: use them sparingly, 1–2 at most. Quality over quantity — specific hashtags beat generic ones.

Most simple emojis count as one or two characters in our counter. Complex emojis — flags, emojis with skin tone modifiers, or ZWJ sequences — may count as more due to their Unicode encoding. This matches how most social platforms count them, but always glance at the platform's native counter before posting if you're right at the limit.
