Rotor Size

[Nelson G]

I have searched on the site and could not find the answer to my question. I am looking to replace the front brake pads and rotors, but I can't figure out what size are the rotos on my 2013 S4 premium Plus with 19" rims. I see 345mm, and 330 mm and I think 360mm. So which size is the original?

Thanks

345x30 front, 330x22 rear.
