An additional thing to consider when measuring the ideal lip width

[Hightwolf]

There are already threads that cover lip width and it's importance in depth, but I didn't see anyone mention lip width to lower face ratio.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5952987/#:~:text=The%20width%20of%20the%20lips,face%20being%20the%20aesthetic%20ideal

.
I saw it mentioned in this study^

This is how it is measured: bottom line length / top line length (*Just to be clear, the bottom line should be on the lips I just placed it lower so that it can be seen.)
This is an example of a 44.5% lip to lower third ratio. The studies claims that 40% is ideal but I will compare this with male models and see.

In this pic of gandy (he's smiling a bit though) the lip width to lower face ratio is 48.9%

Barrett here is at 44.5% despite him having a very wide face.

O'pry has 42% which is why his mouth looks narrow.

Pitt has 41.4% because of his unusually wide jaw.

Carmack, 46%

I think the ideal lip width is surely greater than 40% of the lower face.
I feel like the ideal range is between 42% to 48%.
If you have a wide jaw being in the lower half would be fine, but if you have a narrow jaw it should def be in the higher range.
I may have also not done all the measurements perfectly cuz I wasn't bothered but I'm pretty sure most are within 0.5% correct

Idk but all you need to know is, your mouth's width needs to be = to the IPD, that's all

No that would be way too wide. This is mentioned in another lip width thread.
But if we want to consider it in terms of Lip to Lower Face think of it like this.
ES ratio is around 42% to 46%, but thats with bizygomatic width.
Most people have jaws narrow than their zygos. It can still be good if mouth width is less than ipd.

Carmack's bigonial is actually too much

Even with the mouth being proportionally bigger, it becomes disproportional with the nose and chin.
