Using the Leander class as a reference point, the comparison sets six light cruisers against three heavy cruisers for roughly the same 45,000 tons. An extra 200 tons per Leander might buy more armour or a triple-turret arrangement, with hull dimensions affecting speed. An all-forward layout could leave space aft for torpedoes and aircraft, but retaining a stern turret would let the ship keep firing while withdrawing. Treaty tonnage therefore governed fleet numbers and the tactical compromises built into each hull.

What cruiser tonnage could buy in a Leander
A light-cruiser comparison turns treaty tonnage into a practical design question: more hulls, more protection, or a different turret layout.
