The '''Ricketts E-line''' (esthetic line) is a profile tangent from '''pronasale''' (nasal tip) to soft-tissue '''pogonion''' (front of the chin).<ref name="ceph">{{cite web |url=https://en.wikipedia.org/wiki/Cephalometric_analysis |title=Cephalometric analysis |website=Wikipedia |access-date=12 October 2026}}</ref> Orthodontics asks where the vermilion of the upper and lower lips sit relative to that line. Classic Caucasian adult norms put both lips '''behind''' the line, the upper lip farther back than the lower (often recited as about −4 mm upper and −2 mm lower, with a couple of millimetres of scatter).<ref name="ceph" /> Looksmaxxing borrows it as a quick “do the lips stick out past the nose–chin line” check.

A large nose pushes the line forward and makes ordinary lips look retrusive. A weak chin does the same in reverse: lips look protrusive because Pog′ is back. The line is only as honest as the two endpoints.

[[Riedel's line]] is a different tangent (lips or nose to chin). Do not mix the two.

== Method ==
What actually moves a lip relative to the E-line:

* '''Chin''' — advancing Pog′ with [[sliding genioplasty]] or an implant brings the line back to the lips.
* '''Nose''' — rhinoplasty that changes tip projection moves the other end.
* '''Incisors and lips''' — orthodontics and veneers change lip support; that is dentistry.
* '''Fat''' — a lean face and a full face are different E-line photos. See [[body fat]].

Norms are demographic. Published Caucasian figures are not a universal target, and they are not a PSL cutoff.

== This wiki's view ==
The E-line is a useful profile word next to [[facial convexity]] and [[Riedel's line]]. It is a line on a tracing. This wiki does not treat a mill “E-line fail” screenshot as a surgical plan.
