Rib thickness should be 60-80% of wall thickness. To increase stiffness, it's advisable to increase the total number of ribs instead of the height (in some instances, this may not suffice). Rib height should be limited to three times the wall thickness or less, where possible (this may also be unavoidable in some load cases).
