## What is Instant Ratio?

Beautiful Proportions for Layouts & Typography.

Struggling to figure out the perfect ratios or balanced font scales for your design work?
This app is a smart design calculation tool that instantly computes ideal dimensions based on the Golden Ratio (1:1.618) and Silver Ratio (1:1.414)—just by entering a base value.

It also features a built-in Typography Scale Generator, essential for UI design and building design systems. It supports your creative process with logic and visual harmony.

【Key Features】

Results aren't just listed as numbers—they are displayed as visual layout blocks, making it easy to perceive scale at a glance. Perfect for visualizing size distribution in banners and UI elements.
