# What happens if exceed character limit in comments?

I am aware that for comments we have maximum of 600 characters to type and by curiosity I just happened to type some random words in a comment box. I expected that when comment exceeded 600 characters I will not be able to type but instead it showed - 'you exceeded X characters'. I am just curious but afraid to do this - what happens if I post a comment with more than 600 characters?

• If only there was a way for you to try that yourself...

• What happens is the comment you try to post will be rejected (you will not be able to submit it) unless or until you lower the character count. I.e., SE software ensures that no one can post a comment with more than 600 characters, by design. Dec 28 '20 at 18:50
• @Asaf "but [they are] afraid to do this".

• @AsafKaragila - I think it's nice that the OP didn't to trash up a post with their test comment. Probably unnecessary, but still nice. Dec 28 '20 at 22:12
• Since Asaf mentioned testing it for yourself, I think the Formatting Sandbox can come in handy for such situations. But I also concur with JonathanZ that it was polite of the OP to have asked here first instead of "trash[ing] up a post with their test comment". Jul 2 at 13:32

In a way literally nothing happens. You click "Add Comment" and the situation stays unchanged. The "too long by" flickers briefly, but that's it.

As explained in a comment by amWhy there is a check on submission.

I dimly recall that in the very early days this was handled much less gracefully, and the text in the comment box got cleared instead.

# What will happen when I write a comment longer than 600 words?

As such nothing happens. When you will write the comment longer than 600 words and click on add comment it will display a message "Too long by $$x$$ characters" where $$x$$ represents total characters minus 600. Here is a refrence what happens when I enter something longer than 600 characters-

What actually happens is that as soon as the system finds the number of characters to be more than 600 it says too long by some k characters. If you click on Add Comment as such you won't get any message but your comment won't be added.
