I went here

Keep looking.

Sony A6300 sensor site area = 15.13 µm²
Sony A7CR sensor site area = 13.91 µm²

This is for one single photosite/pixel, and doesn’t really tell you the whole story (i.e. see “engineering” vs “photographic” dynamic range). What matters (for photography) is how many photosites (of a certain type) you have in the given Circle of Confusion area, which in turn is adapted to the total sensor size.

Edit: As mentioned, this has been covered ad nauseum, both on this forum and elsewhere on the web, there is really no need to go through all the motions again and again.

Agreed … I’m done …

I’m back … never seen that as related to DR …

1. there is never an integer number of photosites in a CoC.

2. CoC based on sensor size is derived from an arbitrary number e.g. the so-called “Zeiss formula”.

3. There is an ISO standard for DR which doesn’t mention CoC at all.

So maybe the correlation of DR and CoC is a typical Photography rule-of-thumb with no technical basis.
