There are many different sharks, but I do not know which could be called, "Regular".
But, assuming that you are asking about the shark jaw of a fish, and not the mechanical tool called a, "Shark jaw", the common range is from 2 inches to 15 inches, in my opinion. (There are lots of foot-long sharks in people's aquariums, and of course, in the ocean; hence, the 2" size)
Of course, the jaw of, say, a great white shark can be significantly larger, while the largest shark jaw known (a fossilized shark) is over 12 feet in size, fully opened. If you want to own this monster jaw, you can buy it for around $500 million, as I understand it.

According to the Guinness Book of World Records, the strongest recorded human bite force was 4,337N. While it's hard to measure how much force a shark's jaw can apply, it has been estimated that they can apply over 26,000N.
A jaw crusher reduces large size rocks or ore by placing the rock into a fixed jaw, mounted in a "V" alignment. The fixed jaw plate is the stationary breaking surface, while the movable jaw plate exerts force on the rock by forcing it against the fixed jaw plate. The space at bottom of the "V" is the crusher product size gap, or the size of the crushed product from the jaw crusher. The jaw crusher machine uses motor as its power. Through the motor's wheels, the shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track.

I am looking for this answer, I don't know. I started a collection of shark jaws and would like to know if there is a rule of thumb on how to tell the length by the jaw size. thanks for any help on this

No, the shark was mechanical. The shark did cause quite a bit of trouble though while it was being used.
The Goblin Shark has a retractable jaw
Loch - jaw
The jaw of the shark matched the bite on her arm. Read her book Soul surfer, it explains a lot.
