Yeah, I need to beef up the devices/resolutions listing. What device(s) have 1920x1200?

The maximum scaling option in macOS for 15" retina MacBook Pro's (all 15" retina models since 2012) is 1920x1200. So it's probably used quite a lot.

Select 15" and scroll to Display section.

Might be nifty to just match the list of devices in Chrome Inspector ..?

This may also be of interest .. https://stackoverflow.com/questions/30610143/why-does-google...

I just looked at Responsive Design Mode in Firefox Developer Tools and they also have a list of 16 devices with resolutions (Chrome has 29). There is a lot of overlap in the two lists, but using those would tie into a common tool we use to view sites on different devices.

My monitor, for example. Or do you only design for phones? I'm afraid I'll close your sites sight unseen if you do them that way.

My 2008 Dell Studio 15 laptop :)

I'll be sure to add that as I expand the listing of devices/resolutions.

Also, I thinking that it could be handy to maybe default to the resolution/aspect ratio of the device visiting the page. Would that be handy?

Yeah, I like this idea. It's kind of what I was expecting before I visited the page.
