Frequently Asked Questions

What is aspect ratio?

Aspect ratio is the proportional relationship between width and height. It's expressed as two numbers separated by a colon, like 16:9 (widescreen) or 4:3 (standard).

How does ratio locking work?

When locked, changing the width automatically calculates the height to maintain the ratio, and vice versa. This is useful for scaling images while preserving proportions.

What is the most common aspect ratio?

16:9 is the most common for modern screens, TVs, and video. 4:3 was the traditional TV/monitor ratio. 1:1 is common for social media profile images.
