Rotor size

Hi, so I was wondering if the rotor has to be the size that it's called for? Because I found a rotor that is just one inch bigger in diameter but the screws match up and it fits just fine but will it be a problem is the rotor is just an inch too big? Like can I drive with a little bit bigger rotor or will I not be able to?
also the depths are the same. So basically the only difference with this rotor is it's one inch bigger in diameter than the others and what my car calls for.
