My husband had an old pair of these that we were replacing.  The old pair was 34 x 32 and fit great, however he needed the next waist size up so we ordered a 36 x 32. When the 36 x 32 was delivered it was way too long,  even with boots on.  We returned that pair and instead purchased 36 x 30, which fit great.  So it seems the waist is true to size,  but they are long on length.
