hyprland-wiki/pages/Configuring/Master-Layout.md

The master layout makes one window be the "master", taking (by default) the left part of the screen, and tiles the rest on the right. You can change the orientation on per-workspace basis if you want to use anything other than the default left/right split.

Quirks

The right, "slave" windows will always be split uniformly. You cannot change their size.

However, you can resize the master window.
