How the camera score is calculated

Rear-camera hardware: main camera sensor size (40%, required), optical image stabilisation on main camera (15%), longest optical zoom (15%), telephoto sensor size (15%), ultrawide camera resolution (15%).

This is a hardware score built from specifications. It does not measure actual photo quality, which also depends on image processing.

Inputs, weights and scales for the camera score (formula version 2.6). Values between two points are scored on the straight line between them; values beyond the ends get the end score.

Worked example

The Google Pixel 11 Pro is #3 in the current camera list. Its camera score of 85 comes from these inputs:

The contributions add up to the score. An input that is not confirmed is left out and the remaining weights are scaled up to 100%, except where the category counts an unknown input at the middle of its scale (shown as "counts as 50").
