The midface ratio is the distance from the midpoint of the pupils to the middle of the lips (sometimes to the top of the lips) divided by the interpupillary distance. Concept promoted by Phoenix Wright/Yatterman at missjfacialplasticsurgery.com, Love-Shy forums and PuaHate.
For females, a compact midface is ideal because it supposedly indicates neoteny. For males, however, midface ratio matters less. Even men with long midfaces like Randy Orton, Ian Somerhalder and Nick Bateman are considered attractive to females.
A long face could be natural due to bodily height (taller people have longer faces; e.g. Yao Ming has a long face due to his height). A long face could also be caused by environmental factors such as mouthbreathing (Adenoid face). A long face is deemed to be unattractive by some sluthaters, yet some of these sluthaters themselves are unaware that some of the people they worship (like Randy Orton and Ian Somerhalder) have high midface ratios. This is due to an illusion.

- Yao Ming and J.J. Watt - If you measure the height of their midfaces, Yao Ming's is longer, yet it isn't evident at first sight because Yao Ming has wide-set eyes and a high bigyzomatic width.
