GUI Scaler

Never adjust GUI scale manually again. GUI Scaler automatically scales your Minecraft GUI based on window size — whether you resize, toggle fullscreen, or switch monitors.

✨ Features

• Automatic GUI Scaling — Dynamically adjusts GUI scale when your window size changes
• Intelligent Detection — Uses pixel density detection for optimal readability on any display
• Real-time Updates — Triggers instantly on screen open, fullscreen toggle, or window resize
• Two Scaling Modes — Smart AUTO mode or fully customizable CUSTOM mode
• Multiloader — Works on Fabric and NeoForge (Forge supported up to 1.21.4)
• ModMenu Support — Fabric users get an in-game config screen via ModMenu

🎯 Scaling Modes

AUTO Mode (Default)

| Resolution | GUI Scale | | --- | --- | | 2880x1800+ (HiDPI/Retina) | 3 | | 1920x1080+ (Full HD) | 2 | | 1280x720+ (HD) | 1 | | Otherwise | 0 (auto) |

CUSTOM Mode

Define your own width → scale rules in the config file.
