media queries breakpoints?

Question

I have used many media queries breakpoints in my tests, and i can't find the correct method to use them. Can someone explain it please?
Example(I used this method):
@media only screen and (min-width:1200px){}
@media only screen and (min-width:992px){}
@media only screen and (min-width:778px){}
@media only screen and (min-width:678px){}
@media only screen and (min-width: 480px), (max-width:668px) {}
@media only screen and (max-width: 430px), (max-width:600px) {}
(pardon for my bad english lol)

Answer 1

Zambon if you are asking about different media queries used, than that's depends over the screen size and varies according to the screen of mobile, PC, laptop etc.
