I've only been using 2x images for UI elements and logos. Photos still look fine at standard res (especially if 'Saved for Web' with a .25 blur). A recent project included a 25K 8-bit 2x sprite sheet, and a 13K 1x sprite sheet for LTE IE8. So not much of a difference if limited to elements that really need to be crisp.

Another good approach to small elements like these is using icon fonts. For example, GitHub recently changed all of their nav icons from sprites to a custom icon font called Octicons: Say Hello to Octicons: https://github.com/blog/1106-say-hello-to-octicons https://github.com/blog/1106-say-hello-to-octicons The Making of Octicons: https://github.com/blog/1135-the-making-of-octicons https://github.com/blog/1135-the-making-of-octicons Edit: I realize icon fonts are mentioned in the Smashing Mag article, but GitHub's articles are considerably more thorough.

  Icon fonts just seem to like such a hack to me in a world where SVG exists. Is the entire idea behind using them just that IE 7/8 doesn't have SVG support? How did lack of SVG support even happen? SVG seems like something any modern browser should have had for years.

    Android also lacked SVG support until 3.2. The justification I read was that they deliberately disabled it from their webkit build to save 1MB in the compiled binary. Sad, especially since pre-ICS phones are by far the most prevalent.

      Although a low Res image fallback is OK there.

    You can hint a font. You can't hint an SVG.

      Huh, that is unfortunate. Is hinting still important on devices with such high DPI though?

        It’s not usually the high-dpi devices that you’d be adding hints for. The point is that anything that is going to replace today’s pixel-perfect bitmap graphics still has to look pixel-perfect when rendered on lower-dpi devices, which is going to remain by far the majority of visitors to most sites for a while yet.

    I would love to use SVG, but support just isn't robust enough. Hard to deal with hover/active states too. Icon fonts are one request and easy to style with CSS color and text-shadow (even simulating glows). I just wish there was an easy way to generate a small font set from a the handful of vector elements I need for a given website (custom elements, that is, not using a service like Pictos).

    I believe IE was trying to push the roughly equivalent VML format.

  Nice, I love that they created a large and small version so that the details weren't interpolated away when down sampled. The 'making of' is great, I'm going to forward this to our designers.

I've actually taken it even further and bumped up to 4x+ to account for zooming as well. Especially for charts.
