Questions
What aspect ratio is 1680x1050?
1680 × 1050 is 8:5 (1.6:1). Dividing both sides by their greatest common divisor, 210, gives 8 and 5. That is exactly 16:10, which reduces to 8:5.
How do I resize 1680x1050 without distortion?
Keep the ratio at 8:5: new height = new width × 5 ÷ 8. Dividing both sides by 2, 3, 5, 6 or 10 keeps whole pixels, for example 168 × 105 at ÷10.
What is 1680x1050 cropped to 9:16?
A centered 9:16 crop of 1680 × 1050 is 591 × 1050, which keeps 35.2% of the image. Padding it to 9:16 instead gives a 1680 × 2987 canvas with 1,937 px of bars.
