Up top from center to center it's approximately 1 17/32"
Down bottom (volume and tone knob side) from center to center it's approximately 1 23/32".
The tail peice remains straight while the bottom side of the bridge angles towards the pickups a bit. That's why they are different distances. I only measured one of my Les Pauls, so I don't know if they all have the same measurements. I would think that they would.
