Case studies

Real sites, weighed page by page

Every figure below is the whole page a visitor downloads — HTML, stylesheets, scripts and images together — measured on the live site, not projected from a sample and not taken from the homepage alone. 19 sites, 318 pages weighed.

Why the range is wide: image compression can only remove what is actually an image. A photography-led page loses most of its weight; a text page carrying the same stylesheets and scripts barely moves. Both are shown, because publishing only the good half is how a measurement stops being one.
