In addition to the seat-width, the other dimension that has been shrinking is the seat pitch - the distance between rows of seats. Seat pitch, of course, determines how much leg room you have, whether the seat in front of you hits your knees. A low seat pitch can be extremely uncomfortable - and airlines have been been squeezing seats closer. A seat pitch of 31" seems to be the norm now among most major carriers, down from 32" or even 34" in the past. Now, you have to pay extra to get Economy plus/premium seating to get the 1" of extra leg room, that used to be the standard in the past.
