critisizing is correct if you are measuring a critter. Although it may not be found in the dictionary, it is a southern term in the U.S.A. used to describe the size of a critter when ordinary instruments are not available. Terms such as " bigger than a skeeter", "longer than my arm", "as thick as your thigh" are but a few terms used. Length can be described spreading ones arms horizontally to the approximate and state "it was this long". These are only a few examples of critisizing.
