What are the standard socket sizes from smallest to largest need to know what im missing?

-What is it that your missing Melinda? Got some loose screws up there? Ha-ha. Well, most off the self sets are in 1/8 and 1/16th, not sure what you need 1/16-1/8-3/16-1/4-5/16 and so on. Now 5/16ths is the size of a side post terminal battery and is almost equal to an 8mm in metric. 9/16 is about a 14-15mm...?metric or A/F ?

easier to simply check what sets of sockets are for sale from suppliers. eg snap-on. since these will be selected to fit most component and work needed from a standard socket set.
