This quote from PEX Supply Company:

The Bend Radius of PEX Tubing
The bend radius of tubing refers to the inside curvature of the tubing. This measurement is the minimum radius that you can bend the tubing without kinking it. More flexible materials will have a smaller bend radius, allowing them to bend more before being damaged. Typically, with standard PEX tubing, you can expect it to have a bend radius of 6 times its outside diameter. Therefore, if you have 1/2" PEX tubing (which has a 5/8" outside diameter), the tubing will have a bend radius of about 3.75", making PEX tubing extremely flexible compared to other types of tubing.

This would mean that the center-to-center distance of 1/2" PEX laid out at the closest parallel distance allowed by minimum bend radius, as mentioned above would be 8.125" (3.75 + 3.75 + 5/8).
Serpentine would let you do tighter layouts.
