Resolution & Aspect Ratio Calculator

Convert resolutions, visualize safe areas, compute aspect ratios, and calculate PPI for any display

Enter original dimensions, then type ONE new dimension — the other is calculated to maintain aspect ratio

Width (px)

Height (px)

Aspect Ratio

Width — enter to calculate height

Height — enter to calculate width

Scale Factor

Step 1: Enter original Width + Height

Step 2: Enter ONE new dimension (width OR height)

Result: The missing dimension is auto-calculated to preserve the aspect ratio

Example: Original 1920×1080 → New width 3840 → Height = 2160 (scale ×2.0)
