I’d like to introduce Divvy, a convenient app for macOS that allows you to change window size and position using keyboard shortcuts.

Downloading Divvy

While it’s available on the Mac App Store, you can download a FREE TRIAL version from the official website.

Divvy Keyboard Shortcut Assignment

General

First, launch Divvy and assign a keyboard shortcut to launch Divvy from [Use global shortcut to display panel].

In my case, I’ve set it to Option + D.

Shortcuts

Next, set up keyboard shortcuts for window positioning.

I configured all five types: up, down, left, right, and full screen.

I assigned them intuitively as follows:

Left: Left → L
Right: Right → R
Up: Above → A
Down: Below → B
Full: Full → F

That’s all from the Gemba for using keyboard shortcuts to change window size and position on macOS.
