Frequently Asked Questions
What is aspect ratio?
Aspect ratio is the proportional relationship between width and height. A 16:9 aspect ratio means for every 16 units wide, the image is 9 units tall.
Why does aspect ratio matter?
Maintaining aspect ratio prevents image distortion when resizing. Wrong ratios can stretch or squash images unnaturally.
What is the best aspect ratio for social media?
Instagram: 1:1 (square), 4:5 (portrait), 16:9 (landscape). Facebook: 16:9 (landscape), 4:5 (portrait). Adjust based on platform.
How do I resize while keeping the ratio?
If your original is 1920×1080 (16:9), resizing to 960 width requires a height of 540 to maintain the ratio.
