As you grow your business on social media, it’s important to stay aware of the unique character limits on each platform. Every character counts when talking to your target audience online, so you need to make sure that your copy fits the limit and still delivers a clear message.
Below, I’ve identified the social media counts on commonly used social media platforms in 2025, helping your business effectively plan future posts.

You’ll know when you’ve reached the character limit on each platform, since you won’t be able to add any more content. You might be cut off mid-sentence, or you might be able to view a character count that shows you once you’ve hit that limit.
How Do I Draft an Effective Social Media Post?
As you write your social media drafts with these character limits in mind, the following advice will ensure that you’re creating content with strong messaging:
- Create a strong hook: When you publish a post, most social media platforms will cut off the text after the first few sentences. So, your copy needs to lead with a strong hook that entices your audience to read on. You begin with an interesting statistic or fact, ask a question that your audience might be thinking, or share an industry hot take.
- Stick to the point: Even if a platform like Facebook or LinkedIn has a large character limit, this doesn’t mean you should create a post that’s as long as possible. Instead, make sure that your post is long enough to deliver a clear, consistent message, and only contains key information that your audience will be interested in — don’t waffle!
- Think about additional content: I don’t recommend sticking to text posts only, since creating engaging visual content like videos or infographics can enhance your copy and increase audience engagement.
💡 Top Tip!
If you’re thinking of using AI to write social posts, remember to specify the character limit you’d like the AI to adhere to in your prompt.
