Why Character Count Matters
Exceeding platform limits truncates your content. Instagram captions cut off at 125 characters in feed view — your key message must be in the first 125 chars. Twitter posts over 280 characters cannot be published. LinkedIn posts over 1300 characters get "see more" collapsed.
Does Twitter count emoji as one character?
Most standard emoji count as 2 characters in Twitter's character counter. URLs are automatically shortened to 23 characters regardless of actual length.
What is the Instagram bio limit?
Instagram bios are limited to 150 characters including spaces and emojis. Instagram captions can be up to 2,200 characters but only the first 125 are shown without expanding.
