Web Bloat Score Calculator

TestDome (via Maciej Cegłowski):

Page web bloat score (WebBS for short) is calculated as follows:

WebBS = TotalPageSize / PageImageSize

TotalPageSize is the size of all requests, and PageImageSize is the size of a full-page screenshot.

The larger the WebBS, the more bloated a web page is relative to its image representation. For example, Tim Berners-Lee’s homepage has a WebBS of 0.204, which makes it really efficient, while Amazon has score of ~20, making it bloated.

It’s a crude metric—for example, it downsamples retina images, thus penalizing pages that include them—but interesting nonetheless.
