आस्पेक्ट रेशियो कैलकुलेटर — अक्सर पूछे जाने वाले सवाल

What is an aspect ratio?

An aspect ratio describes the proportional relationship between the width and height of an image, video display, or screen (such as 16:9 widescreen or 4:3 standard display).

How does the calculator reduce fractions to standard ratios?

The calculator uses the greatest common divisor (GCD) algorithm to simplify raw pixel resolutions (e.g., 3840×2160 or 1920×1080) into their lowest proportional integer ratio (such as 16:9).

Can I calculate a missing dimension?

Yes. Given an original width and height, you can enter either a new target width to compute the proportional height, or enter a new target height to compute the proportional width.

Which standard display presets are included?

The tool includes presets for 16:9 (HD / 4K UHD), 4:3 (Traditional TV / iPad), 21:9 (Ultrawide Cinema), 9:16 (Vertical Shorts / Reels / TikTok), and 1:1 (Square).

Does this tool require uploading an image?

No. It is a mathematical geometry and resolution calculator that functions directly from numerical inputs without needing any image upload.
