2.91 - where can I change animation size I just want to change the output of the rendered animation (CTRL+F12)

it used to be accessible, but I cannot find it anymore
where can I post a feature request so that the dev's make it even more hidden and cryptic ?

I tried looking in blender of course, then outlook, and thunderbird, I tried &quot;device manager&quot; in windows, and I tried to search for these settings on my android phone....one never knows
next step, I'll apply for a trip on mars, these settings got to be there...everywhere but in blender since v 2.8
thanks
It's right there, where the red circle is.
