Default Amount different classes of bobbins hold, comparatively

Does anyone know if this information is available? It seems to me like class 15 look like they hold more, but I've never measured it. Oh! I could weigh empty and full ones, and compare the weight of thread they hold. If no one knows where this info is, I'll try this.
