Window-resizing, works on any resolution

On top of having 2 Macs, I sometimes change screen resolutions — so I’m hoping for a shared, resolution-independent way to size and position windows (Finder mostly, but any app, really). I use (and love) BetterSnapTool, but it doesn’t have a setting for what I want: ¼ display width, full-height.

My thinking is: I need to get the display’s current resolution, divide its width by 4, then set the current window width and top-left position accordingly.

I’m stumbling on a) everything related to screen size seems to be about SETTING it — not GETTING it and b) not being able to figure out parsing tokens like ScreenResolutions that return a set of comma-delimited values.

This simple macro shows a couple ways (yellow and green actions) to get the resolution:

For the green example, you reference the fields with the [n] construct, where n is the field number you want to retrieve from the variable.

That’s awesome, thanks! I’ll dig into this ASAP! :sunglasses::+1:

There are probably even easier ways to do this; the above are just the ways I stumbled upon in my own testing and development :).


Yellow actions did the trick! Thanks again — this has been on my back burner for months.

Unless I'm missunderstanding what you are after, Keyboard Maestro can size windows proportionally to whatever screen the Macro is run on directly without any further steps:
