01 What is the Twitter/X character limit?
Twitter/X has a character limit of 280 characters for standard posts. URLs count as 23 characters regardless of their actual length. Tools Oasis shows you exactly how many characters you've used and how much room you have left.
02 What is the Instagram caption character limit?
Instagram captions can be up to 2,200 characters long. However, captions are truncated after about 125 characters in the feed, so put your most important content first. You can use up to 30 hashtags per post.
03 What is the LinkedIn post character limit?
LinkedIn posts can be up to 3,000 characters. The platform truncates posts after about 140 characters with a 'See more' link, so make your opening lines compelling.
