Don't forget about seat width too. It's less than an inch more, but the seats are wider on the Max as well (thanks @LegalTender for the reminder!).

That's right. A 1970 737 fuselage is exactly the same width as a 2019 737 fuselage. The only way to increase actual seat width would be to make the aisle ridiculously narrow.

The first B737s seated less than 100 pax and were known as Fat Alberts. Little resemblance to today's airplanes.

It is relatively easy to make a plane longer or shorter as a variant. Making it wider is essentially making a new plane.

The middle seats were "overflow" needed on big city pairs on high travel days. It's like a movie theater in that the vast majority of the time, you can find a seat with an empty seat on both sides of you. Only if you insist on seeing a popular movie the day it comes out do you have no choice but to sit between two other people.

Minimum aisle width less than 25 inches from the floor is only 15" for aircraft capacity of 20+ passengers. Passenger evacuation times may demand more width depending on cabin length and number/type of exits. Put yourself on a Bombardier CRJ (-200, -700 or -900) with a tape measure and then compare aisle width to a WN 737 or Max.
