Kolanaki@pawb.social 5 days agoHuh. I guess I just never saw the different sizes having a different sized spindle hole. My dad has a collection of records, and there are two different sizes of records among them, but they all have the same sized hole in the center. However, none of them appear to be 45s. They’re all 10’s or 12’s.

That’s awesome, you’re one of today’s lucky 10,000.
It supposedly had something to do with calculus and the ratio between the diameter of the inner most groove to the diameter of the outermost groove being optimal at that size, but I’m not sure how much of that is genuine or just marketing. I’ve also heard that the larger hole is better for the mechanisms in jukeboxes.
