About Us
Our mission: accurate calculations, zero friction.
Aspect Ratio Calc is a free, browser-based toolkit for anyone who works with dimensions, screens, and media. We build calculators that give instant, accurate results without accounts, downloads, or paywalls.
What We Build
- Aspect Ratio & Resizer — simplify ratios and scale dimensions while preserving proportions.
- DPI / PPI — measure true pixel density for screens and displays.
- Pixel Converter — convert between px, inches, cm, and mm.
- Resolution & Megapixel — analyze resolution, categories, and MP counts.
- Print & Screen Size — plan physical output from pixel resolution.
Our Principles
Your inputs never leave your device. Calculations run locally in your browser, so your data stays private by design. We keep the interface fast, accessible, and easy to use on desktop, tablet, and mobile.
