Can I use a micro sim card in an unlocked iPhone 5s?

I have an unlocked iPhone 5s and I'm thinking of cutting my micro sim card to fit the iPhone 5s sim tray. Will my unlocked iPhone 5s work with my sim card? Please I really need answers.

It will if you cut it correctly into nano size, but if you think you'll mess up just buy a nano sim and transfer your number onto that.
