I wrote this[0] post on how I use OBS to share a 1080p sized portion of my upper left ultrawide monitor through Microsoft Teams. If you can share just a specific window, then this should work with google meet.

I have a shortcut setup in my window manager app to resize the current window to 1920x1080 specifically for screen sharing.

By “window” do you mean “display”?

I wish that when you shared an app window, Zoom would let you scale that to fit the full screen share. That way you could present a reasonable image of a window to viewers while using an ultra-wide monitor.

No, I mean the window. Usually I’m sharing chrome or a code editor via zoom.

I share a tab/window and resize that window to be approx 16:10. Shows up nicely for others and I can still see the rest of my screen.

If I had another window open for chat/notes/emails I can still have that at half my ultrawide and just deal with a bit of overlap on my end

I did the same but not being able to share a terminal and a browser window at the same time is tough.

Ended up using OBS and sharing the obs preview window instead. This lets me add fun gifs and overlays as well to my screen for loading or success.

I have had a 43" monitor at work and at home for a while, and the solution I've used throughout the pandemic has been to share only a region of the screen, or to share a single application or window, which I often shrink down to a "laptop" size" in order to share my screen with colleagues. That still leaves plenty of real estate around the "shared" window that is not visible to others, but is useful to me.

Zoom lets you share a region of your screen if you click the advanced tab when sharing.

Yeah, sadly we use Google which does not.
