What is the standard widescreen aspect ratio?

16:9 is the universal standard for modern computer monitors, high-definition television (HD, 4K, 8K), and YouTube videos.

How does the tool simplify aspect ratios?

It uses Euclidean Greatest Common Divisor (GCD) math to reduce pixel dimensions (e.g. 3840×2160) into standard fractional ratios (16:9).

Can I scale dimensions proportionally?

Yes. The proportional scales matrix lets you preview exact resolutions scaled to 0.5x, 0.75x, 1.5x, and 2x.
