Questions
What aspect ratio is 2560x1600?
2560 × 1600 is 8:5 (1.6:1). Dividing both sides by their greatest common divisor, 320, gives 8 and 5. That is exactly 16:10, which reduces to 8:5.
How do I resize 2560x1600 without distortion?
Keep the ratio at 8:5: new height = new width × 5 ÷ 8. Dividing both sides by 2, 4, 5, 8 or 10 keeps whole pixels, for example 256 × 160 at ÷10.
What is 2560x1600 cropped to 9:16?
A centered 9:16 crop of 2560 × 1600 is 900 × 1600, which keeps 35.2% of the image. Padding it to 9:16 instead gives a 2560 × 4551 canvas with 2,951 px of bars. That canvas is rounded, not exactly 9:16: the exact padded side would be 4551.11 px tall. The smallest exact 9:16 canvas around it is 2565 × 4560.
