Why rank by thinnest?

Every reader here uses an e-ink screen with a built-in front light, so the real differences are specific: screen size, how sharp the text is, whether it shows colour, whether the light can turn warm for night reading, whether it carries an IPX8 waterproof rating, how much it weighs in one hand, and how much storage the base price buys.

The overall ranking on the Kindle Colorsoft alternatives page weighs every published spec. This page answers one question only, so a model can rank first here and lower overall. The DupeScore beside each model is the overall figure.
