Frequently Asked Questions
Q. What is aspect ratio?
Aspect ratio is the proportional relationship between an image's width and height, typically expressed as two numbers separated by a colon (e.g., 16:9).
Q. Why should I maintain aspect ratio when resizing images?
Maintaining aspect ratio prevents image distortion, keeping your visuals looking professional. Stretched or squished images appear unprofessional and can negatively impact user experience.
Q. What are common aspect ratios I should know?
Common ratios include 16:9 (widescreen video), 4:3 (traditional TV/monitors), 3:2 (DSLR cameras), 1:1 (square, for Instagram), and 9:16 (vertical video for mobile).
Q. How can I calculate aspect ratio manually?
Divide the width by the greatest common divisor (GCD) of width and height, then do the same for height. For example, 1920×1080 has a GCD of 120, resulting in 16:9 ratio.
