A bit of arithmetic will tell you about widths - 1" ~ 25c, 1 1/8 ~ 28c and 1 1/4 ~ 32c. I have Paselas on 5 bikes and am well pleased. I have 27 x 1 1/4 on "the mule", 87 Voyageur, as that rough rider may have to handle anything from smooth macadam to 2a modified. I have 27x1 1/8 on two others and really like those. My preferred size. On my bikes they really do measure out to 28 mm wide. Roll well, turn easily and provide a comfortable ride.
I may be a grouchy old fart though, so "comfortable" is in the seat of the rider, don-cha-no.
