Image Question (dealing with the measurement of a super hot ass)

[tetsuo]

Okay so this chick on YT, xxjesspatxx, makes clearly fake fart vids, However, her ass is simply amazing and that alone draws me to her vids. Anyway, out of boredom and curiosity I was wondering if there was a way to measure, using the image, how large her ass is.

Here is the shot:



I was thinking maybe using the other girls head as a reference point, however I am still now sure how to go about doing this..if anybody has any tips or anything please post.

Image measurements:

Image dimensions - Vert. 6.53 inches Hori. 11.17 inches

Ass - Vert. 4.56 inches Hori. 5.35 inches

Head- Vert. 3.20 inches Hori. 2.04 inches

Now I just need to scale that shit..any suggestions?

Yes! OMG HER! Her ass is AMAZING. I wonder why she insists on telling people her farts are real when clearly they are not. Keep in mind though the reason why her ass may look big is that she's sticking it close to the camera, whereas her friend's face is several inches away. You know what I mean?
