I have a kohler toilet and I often have to plunge it, at least once a week.
It seems to plug easily without any abnormal use.

I am looking at getting a new toilet and notice that trapway sizes are often
listed.

Will a larger trapway prevent a toilet from clogging? *I see that toto
toilets that I am looking at have a 2 1/8 " trapway. *another toilet that I
am looking at lists the trapway being 1 3/4 " minimum

There are a number of factors and trap size is important. However
sometimes too big is bad as it can mean less force from the water.
Generally larger is better however.

Also important is a "fully glazed" trap. That is always a good
thing.

Even after all that there are a number of little changes in size
and shape of the bowl size of valve etc all together make for serious
differences in performance.
