Stop doing the maths manually. The Aspect Ratio Calculator GPT delivers the precise aspect ratio for any resolution in an instant — just type your dimensions in the standard WxH format and get your answer immediately.
What is Aspect Ratio Calculator?
Aspect Ratio Calculator is a focused, single-purpose ChatGPT assistant built to calculate aspect ratios quickly and accurately. Using the Euclidean algorithm — the mathematical standard for finding the greatest common divisor — it reduces any pair of width and height values to their simplest ratio. Whether you are a designer setting up a canvas, a video editor choosing an export format, or a developer defining responsive breakpoints, this GPT gives you the correct ratio without any manual calculation. It recognises standard resolutions like 1920×1080, 1024×1024, and 900×1600, and handles any custom dimensions you throw at it.
How Does It Work?
The GPT accepts input in the format of widthxheight — for example, 1920×1080 or 1600×900. It processes the values using the Euclidean algorithm to find the greatest common divisor and returns the simplified aspect ratio. If the input does not follow the correct format, it immediately prompts you with a clear error message so you know exactly how to correct it. No extra steps, no explanations unless you ask for them — just a clean, instant result.
