Gemini Ultrawide

About

Gemini Ultrawide is a lightweight CSS override extension engineered to remove the default 48rem (768px) width constraint on the Gemini web interface. By expanding the structural containers, this extension allows the chat and prompt areas to utilize your monitor's full available width, significantly improving the visibility of dense data, wide tables, and long-form code blocks.

Core Features

- Dynamic Viewport Expansion: Stretches the main conversation and input containers up to a maximum of 2000px, centering seamlessly on ultrawide monitors.
- Data Table Optimization: Forces Markdown tables to scale horizontally across the full expanded width, preventing forced text-wrapping and improving the readability of complex data arrays.
- Media Constraints: Implements an aspect-ratio lock that caps image and video heights at 600px. This prevents visual media from distorting or overtaking vertical screen space when the horizontal axis is widened.
- Ergonomic Margin Control: Retains calculated padding and border-box sizing to prevent accidental horizontal scrolling and maintain visual tracking efficiency during extended reading.

Privacy & Performance

- Zero Overhead: Operates strictly via a localized CSS injection without running heavy background scripts.
- No Data Collection: Does not read, store, or transmit your prompts, responses, or account data.
- Secure Scope: Requires minimal manifest permissions, executing exclusively on the gemini.google.com domain.
