Piston-to-Bore Clearance

When a piston manufacturer specs the piston-to-bore clearance is that clearance for each side or the sum of both sides?

As a specific example, a set of Badger pistons for a std bore are 3.997" in diameter. Badger specifies a .0025 minimum clearance. Is the bore diameter that they are after 3.9995" or 4.002"?

they make it simple for you so you only have to check one side. 3.995" would be the minimum bore diameter in your example.

i believe grclark351 meant 3.9995. (3.997 + .0025)

a 3.997" diameter piston won't fit into a 3.995" bore,
at least not without breaking something...

I figured that was what he meant, but thanks for clarifying just in case!
