Glenn is mostly right, and his reference to Sheldon is a good one.
However, the answer is incomplete.
Perhaps 20 years ago there were only 2 main link sizes- 1/2"x 1/8" for single speeds and enclosed gear hubs and 1/2"x3/32" for derailleur drivetrains. Now, there are many different chains, from the ultra thick to the super narrow. So, ultimately, there is no longer a "typical" size.

Most links are about an inch (two pieces to a link). if they stretch to 11/8 it is time for a new chain.
The chain in use on modern bicycles is a roller chain with a 1/2" pitch. Chain comes in either 1/8" or 3/32" widths. 1/8" is used on the common low cost coaster, three speed, fixed gear and track bicycles, and 3/32" is used on derailleur-equipped road bicycles such as racing and touring models.
P.s. (Smirk) 3/32" is the inside chain measurement. It is the same on ten speeds also. The outside chain measurement varies on super and ultra narrow chains. (Yeah I like to play games too.)
