When adding images to questions and answers, what is the maximum width it can be before it gets resized?

1 Answer 1


640px is the width of the images. So that's the size they get scaled down to.

As from this CSS rule:

.post-text img {
  max-width : 640px;

Please note that this also illustrates that images are not scaled down server-side. They are always original size, just displayed smaller.

Of course, I myself have that overwritten, see Images can be pushed outside the boundaries of a post by using nested lists

  • this appears to be too large. I'll add a pictured of a 660px circle to my question so you can see. Commented Oct 30, 2012 at 12:53
