Configure Plasma to only resize windows to only 50% of the view?

I'm using Plasma 6.0.5 on Arch, and one thing I keep having issues with is the way KDE handles Meta+<Left/Right>. It uses a LARGE quantity of space on the right or a small quantity on the left. How can I reset it back to using only 50%? (I've looked up potential solutions, and I've adjusted KDE's "snap zones" (what pops up when pressing Super+T).
