Requirements and installation
Minecraft 1.21.1–1.21.11 · NeoForge · Java 21
Choose the JAR for your Minecraft version and place it in your client’s mods folder. GUI Scalar is client-side. Sodium is optional. The interface is available in English and Russian.
The scale starts at 1.00. Its maximum depends on your window resolution. At 1920 × 1080, the maximum is 4.50. Fractional values can soften pixel art and text edges. Custom HUDs that draw in physical pixels may need separate support.
