Facial cleanser portion sizes

When I wash with my regular face wash I use a small dime sized amount because it lathers up.  But in the morning I like to use something more gentle like Cetaphil Gentle Skin Cleanser or CeraVe Hydrating cleanser.  When I use these cleansers, I feel  like I need to use a full quarter sized amount or a pump and a half to feel clean.  Am I doing it wrong? Or do you find this to be true as well and that's just how these Gentle cleansers work?
