The Shielded Twisted pair cable is not commonly used because of a few reasons; some of which are:
Difference between coaxial cable and STP cable used for computer networking?
Shielded Twisted Pair (STP) is twisted pair cabling includes a shield.This type of cabling is not commonly seen in modern LAN networks deployments till 2011 however some newer very high speed Ethernet technologies may require a cable that has a shield.
Shielded Twisted Pair (STP) connector is the Registered Jack 45 (RJ-45) connector.

I didn't find a specific reference (perhaps that part isn't standardized), but it looks like the standard UTP cable has a thickness of about half a centimeter. Note that there are other kinds of cables - some of the kinds include UTP (unshielded, the most commonly used cable, mentioned above), STP (similar to UTP, but shielded, therefore a little thicker), and coaxial cable. Optic fibers are also used for Ethernet.I didn't find a specific reference (perhaps that part isn't standardized), but it looks like the standard UTP cable has a thickness of about half a centimeter.

STP is also called coaxial cable
STP is more reliable due to shielding.
An STP cable is a Single Twisted Pair cable, and it has a few advantages. One advantage is that it is more secure than other cables. It also transmits faster, and has a greater resistance to interference.
