Width is as long as her the length between whisker to whisker, which would be about 20-25cm perhaps. This is the way cats can gauge as to whether they will fit into a tight space or not. A female (desexed) ragdoll would be around 45cm in length, and about 35-40cm tall. No breeder I know of measures height/width of cats. You go by the weight. Male Ragdolls average 16-18+ when full grown at 3-4 yrs old. Females are a few pounds lighter (about 14 lbs).
