Jsputer GUI Mod

Vanilla Minecraft only lets you set the GUI scale to whole numbers: 1, 2, 3, 4. On a lot of monitors, 2 is too small and 3 is too big. This mod adds 2.5 to the list. Pick it in Video Settings and the interface scales halfway between 2 and 3.

As of writing, this is the only GUI scale mod for 1.21.11 that supports non integer values without the reduced quality other options have on this version. The HUD is rendered at integer 3 internally and downscaled to 2.5 with linear filtering, so it stays as crisp as the game's pixel art reasonably allows at a fractional scale. Mouse position lines up with what's on screen.

How to use it

Open Video Settings (vanilla or Sodium). Cycle GUI Scale until the label reads "2.5". That's the new slot the mod inserts. Everything above it shifts up by one (the old "3" moves to the next position, the old "4" comes after that, and so on). Cycle to any other slot to use a normal integer scale.

There's also a keybind under Options → Controls → Jsputer GUI Mod that toggles between 2.5 and 3 on one button. It's unbound by default, so set it to whatever you want. Handy if you also run a client that draws its own custom GUI at integer scale and want to switch quickly.

Compatibility

• Minecraft 1.21.11
• Fabric Loader 0.19.2+
• Fabric API: any current version for 1.21.11
• Sodium 0.8.x: fully supported. The "2.5" label shows up correctly in Sodium's settings screen too, via Sodium's official Config API.

Heads-up

• Fractional scaling will always look slightly softer than integer scaling, because Minecraft's UI art is drawn for whole number sizes. This mod minimizes that as much as it can, but it can't turn pixel art math into something it isn't. It still looks much better than other 1.21.11 fractional scale options.
• Feather Client's own custom GUI overlays are not supported by this mod. If you use Feather, bind the toggle keybind and press it before opening Feather's menus.

Future

I made this mod because my friend Jsputer asked me to. If this gets used, I'm open to adding more, so open an issue on GitHub to request a feature.
