Drain plug size?

[my95mark8]

Anyone know what thread size the drain plug is? I want to have a gasket ready for next oil change, but need to know the size. I have some at work, just want to make sure I have the right one.
Thanks.

I bought a magnetic drain plug from O'Rielly's. it came with a new gasket. not sure on the thread size.

Thanks.
Maybe I'll do that, or just gather as many different ones as I can, and hope I have the right size.
