Its neither. PEX is measured by CTS (copper tubing size). This basically means that PEX and copper pipes have the same OD, the only difference being wall thickness. For all standard PEX tubing sizes (3/8" through 1"), CTS of PEX is 1/8" less then it's OD. For instance, 3/4" PEX has an OD of 7/8", and 1/2" PEX has an OD of 5/8". You can read more about this here.
