What makes the ipd appear bigger/smaller

[Deleted member 26824]

Me and my brother (chad version of me) have about the same IPD (~60mm-58mm; +-2mm), but the interesting thing is that his doesnt look small but rather harmonizes with his face and its not a failo at all in his case.

therefor there must be something about the face that effects the perception of ones IPD. Anyone knows? My only guess would be fhwr, because he has a wider face.

I’ll just drop this idk if it fits the context

I just figured it out myself pretty much: combination of pfl and fwhr and eye shape it must be (not sure if uee has an effect)

in 2018 PSLers suggested that a stronger nasion (the high part of your nose between the eyeballs) gives the impression of a wider IPD
