The mouth aspect ratio


You might be wondering; what is this ratio?

This ratio decides whether your mouth is to long/short or if its to thin/thick


So how do we measure this?

1. we are going to measure from the left lateral commissure to the right one.

1754858402432


2. We are going to measure from the highest upper vermillion to the lowest bottom vermillion
1754858953433


3. We calculate the ratio, this is done with this formula, Width:Height
And than round the answer off on 2 decimals



So what is the ideal?
After analyzing some top male model faces ive concluded that the ideal range was between 3.0-3.5 for white people.
For black people the range is lower due to them having thick natural lips, i could see this ideal range being 2.6-3.0

Good, ~3.1 Screenshot 20250810 231441 ImageMeter
Bad, ~2.5 Screenshot 20250810 231003 ImageMeter


Measuring tool: Image meter, its available for free on mobile and pc


Obviously ratios like lower lip : upper lip, mouth width : bizygomatic, mouth width : bigonial width matter aswell.




Disclaimer: these ideal ranges arent perfect yet, ill need to do some more research, so dont take these numbers to serious although they are in the good range.

the mouth to nose is interchangeable,

big nose could make a good wide mouth look bad on paper.

if nose is to large it could potentially make a good mouth seem bad on paper.

mouth to nose matters to an extend.

how does that make the ratio irrelevant?
Whats your ethnicity?
 
He looks way better here, first photo you provided was awful

if your lips are about 43% of bizygomatic width and about 45% of bigonial width than your lip width is good.

yeah this guide is good to figure out if the width matches the height, its the same as the eye aspect ratio.

Isnt 43 and 45 too much? How come my lips are objectively wide but compared to my jaw it is 39%. Maybe my jaw is too wide?

bigonial width should be around 90%

43 and 45 is quite high but favorable imo

39 and 42 is also good
