How treaty limits restrained interwar ship growth

How large might destroyers and sloops have become by World War II without treaty restrictions?

Both types might have reached roughly 3,000 tons, while unrestricted battleship competition could have produced much larger capital ships.

Treaty displacement ceilings placed a real brake on natural design expansion. Without those limits, destroyers and sloops might both have reached roughly 3,000 tons by World War II. Capital ships could have grown even more dramatically if competitive building had continued unchecked. Treaty-driven restraint interrupted technical pressures that otherwise pushed each type upward.
