The little icon in the address bar and the bookmarks menu is sixteen pixels square, and most companies use a shrunken copy of their full logo. It rarely works. A few tips from the last dozen we have drawn.

• Use one letter or one shape from the logo, not the whole thing.
• Draw it at 16 by 16 pixels, pixel by pixel. Don't just resize.
• Check it on a white and a grey background, since browsers show both.
• Save it as a real .ico file in the root of the site so older browsers find it.
