Need exact media queries for Kindle Fire

Question

I'm designing for the Kindle Fire, but am not finding correct information about the CSS height/width.

On my two devices, this is what I measured:

Fire 7" 2015

600 x 1024

Fire HD 8" 2018

601 x 962

I thought that it was always either 600 or 800 (and maybe more for bigger, newer ones), but that is clearly not the case.

Are there exact media queries (and I mean 601 exact) for the Kindle devices?

Can I trust that 601 will always be the larger 8" screens?

Answer 1

I collected information on my website to see what size devices people were using.

$(window).width();

These are the widths that can used for CSS media queries. The model number (KFSUWI) is from the user agent. I then Googled the tablet size (HD 10) using the model number. The widths were calculated with Javascript running on the page.
