Re: [csswg-drafts] [css-fonts] Proposal to extend CSS font-optical-sizing (#4430)

Aren’t we counting angels on pins? We seem to be blissfully assuming that we all know what “Actual Size” or “100% zoom” means. The scale factor of so-called “actual size” to “real distance measured off the screen with a ruler” **varies tremendously and is barely documented**. Where can I find a table which states this scale for all iOS devices, or all Macs, or all Samsung phones, or all Surfaces? Why isn’t data so fundamental included in widely published “tech specs”?

A personal vent:

On the built in screen of my MacBook Pro, “Actual Size” increases significantly when I attach an external display, unmirrored. Possibly this new scale depends on the resolution of that display, possibly it always does that with external displays. I have no idea how to keep it at its native “Actual size”. How opsz is supposed to cope with this, I have no idea :-(
