Questions
What aspect ratio is 1920x1440?
1920 × 1440 is 4:3 (1.333:1). Dividing both sides by their greatest common divisor, 480, gives 4 and 3. That is exactly 4:3.
How do I resize 1920x1440 without distortion?
Keep the ratio at 4:3: new height = new width × 3 ÷ 4. Dividing both sides by 2, 3, 4, 5, 6, 8 or 10 keeps whole pixels, for example 192 × 144 at ÷10.
What is 1920x1440 cropped to 9:16?
A centered 9:16 crop of 1920 × 1440 is 810 × 1440, which keeps 42.2% of the image. Padding it to 9:16 instead gives a 1920 × 3413 canvas with 1,973 px of bars. That canvas is rounded, not exactly 9:16: the exact padded side would be 3413.33 px tall. The smallest exact 9:16 canvas around it is 1926 × 3424.
