How the ratio is calculated
Divide both sides by their greatest common divisor (GCD). The GCD of 1200 and 628 is 4, so 1200 ÷ 4 = 300 and 628 ÷ 4 = 157, which gives 300:157. In CSS that is aspect-ratio: 300 / 157; with the older padding trick the height is 52.3333% of the width.
300:157 is not one of the classic ratios; the closest standard is 16:9, 7.48% off. An exact 16:9 image 1200 px wide would be 675 px tall instead of 628, so fitting one into the other means cropping or bars.
