What should be the ideal chin width?

[Improver]

I haven't seen much info about this in exact mm.
I'm finishing my revision implant design and I'm probably leaving it at 28mm (counting only the straight part) but this just an eye measurement because last time it was 38mm and it was too much.

I've only seen a study who places the average male chin width around 27-30mm

Sligthly narrower than the oral commisures.

Would be ideal to have his exact measurements, or ct scan of chads like him
