What size front derailleur clamp do I need?

I am putting a new group on my bike and need to know what size front derailleur clamp I need. I have a scott S30 and on their website it lists the seat post as: Scott Alloy 31.6/300 mm would that mean I need a 32mm clamp? Thanks in advance for any help, I truly appreciate how helpful so many of you are! :)
