Aspect Ratio Calculator — Image & Video Ratio Finder Find the exact aspect ratio of any image, video, or screen size with this fast, accurate aspect ratio calculator. Enter a width and height in the aspect ratio calculator and get the simplified ratio, the decimal equivalent, the common name, and a full scale table in one click. What is an aspect ratio calculator? An aspect ratio calculator is a tool that takes a width and height in pixels and reduces them to the simplest whole-number ratio. For example, the aspect ratio calculator converts 1920×1080 to 16:9 automatically. The aspect ratio calculator also identifies the common name (HD / Widescreen), gives the decimal value (1.7778), and generates a table of common sizes at the same ratio. Why use an aspect ratio calculator? Without an aspect ratio calculator you have to compute GCD (greatest common divisor) manually and then divide both dimensions. The aspect ratio calculator does this instantly. The aspect ratio calculator saves time for designers, video editors, photographers, and developers who constantly work with different resolutions and need to match, verify, or scale them. What the aspect ratio calculator calculates When you enter dimensions into the aspect ratio calculator you receive: Simplified ratio: The aspect ratio calculator reduces 3840×2160 to 16:9, 800×600 to 4:3, and any custom size to its lowest terms. Decimal value: The aspect ratio calculator shows the ratio as a decimal (16:9 = 1.7778), useful for setting CSS aspect-ratio or canvas proportions. Common name: The aspect ratio calculator identifies well-known formats such as HD / Widescreen (16:9), Standard TV (4:3), Square (1:1), Ultrawide (21:9), Vertical Mobile (9:16), Photography (3:2), Univisium (2:1), and SXGA Monitor (5:4). Scale table: The aspect ratio calculator generates heights for 320 px, 640 px, 1280 px and 1920 px widths, so you can plan responsive sizes at a glance. Swap button: The aspect ratio calculator lets you flip width and height in one click to check portrait orientation. Copy button: The aspect ratio calculator copies the simplified ratio string to your clipboard.
