Ideally, they should be under 100 KB to work well on the web.<\/li>\n  <li>High-density (Retina) mobile devices may still need 2\u00d7 dimensions, but you must balance that with file-size impact.<\/li>\n  <li>Use cropping\/aspect-ratio consistent with design so no essential content is cut off on mobile.<\/li>\n<\/ul>\n<p>The best image size for a website is not a fixed pixel dimension, but rather: serve a file sized to the display container plus device pixel ratio, and keep file size small for performance.

Upload the image at that dimension (or provide it via srcset) so that the browser chooses the appropriate size. For example, if the image displays at 400\u00d7300px, provide 800\u00d7600px resolution for the retina.<\/span><\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"<p>TL;DR: Choosing the best image sizes for websites is important in order to maintain their responsiveness, SEO, and speed.
