ShortRatio Mod
ShortRatio is a client-side Fabric utility that forces the game window into a 9:16 viewport, the shape used for vertical short-form video.
What it does
On Minecraft 1.21.x, the mod fits the game view into a 9:16 frame and paints the unused edges black, so footage meant for vertical platforms can be used as recorded. Only the player's own client changes; a server or other players see nothing different. Builds cover 1.21 – 1.21.8 on Fabric, released under the MIT License, though the code is not open source.
Key features
Fixed 9:16 viewport
The game image is constrained to a vertical 9:16 ratio while the mod is active, matching portrait video frames.
Toggle with F9
Pressing F9 turns the black bars on or off during play, so the view can be switched without restarting.
Built for short-form capture
The mod was made for creators recording Shorts and Reels, where it saves time that would otherwise go to retakes and cropping.
