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.
The jaw of the shark matched the bite on her arm. Read her book Soul surfer, it explains a lot.

A shark jaw should be 40 feet long

A Big Mac!
No. Their teeth are like sand paper, and they do not have enough jaw strength to inflict any real pain.

How come your jaw become small when pressure is applied? No,it do not make your jaw bone smaller.The high pressure may make your muscles contract and make them stiff leading to less jaw movement.So you might get a feeling of smaller jaw.
The size of Tiger shark's (Galeocerdo cuvier) teeth depends of the specimen lenght, and - amazingly - the position of each tooth in the tiger shark's jaw do not differ very much for their size.Whatever is the location in the jaws (upper and lower), all teeth are aprox. the same size, all robust and serrated.The average tiger shark lenght is 3 m to 5 m; there are larger specimen beyond these upper limits, with a max. 7.5 m lenght and about 810 kg.However, in Australia, an exceptionaly large female specimen, caught in 1957, weighed an exceptional 3,110 kg!So, it's difficult to say what is the maximum size of a tiger shark tooth. The least I can say is that a large tiger shark have teeth 1 and 5/16" long.
Tiger sharks eyes have excellent vision in low light and can detect electric fields and tiny vibrations in the water. They can also adjust their eyes quickly according to how light or dark the water is. These adaptations allow the tiger shark to detect hidden prey. The jaw of the tiger shark is adapted to be wide and powerful, enabling it to eat and destroy anything. The tiger sharks teeth are adapted to be very sharp and serrated, so that it can tear up all its pray, including seals, birds, fish, other sharks and even turtle shells! The teeth are also replaced over and over through the life of the shark. This is so that when the tooth wears down, it is simply replaced by a new tooth. The tiger shark also has lateral line receptors . These are thin lines on the body that sense vibration movement,water pressure, temperature and sound. These help the shark to detect prey. The shark also has a great sense of smell, which helps them to detect prey from a long way away. Tiger sharks have stripes on their body, which help them to survive because it helps them blend in. Tiger sharks have fins that help them to swim so they can escape from predators, but they also have them to catch prey. The caudal fin is the fin with the most power, and it really proprels the shark along.
