How large could battleships grow without naval treaties?

Without naval treaties, what tonnage might battleships have reached?

Perhaps around 100,000 tons, with the real constraint coming from affordable fleet numbers and infrastructure rather than a single technical barrier.

Warship size was increasing before Dreadnought, and the growth from early dreadnoughts to Hood was substantial. Without treaty limits, affordability and the number of ships needed would still constrain displacement. Larger ships also require investment in docks and other facilities, with bridges and canals imposing further limits unless rebuilt. Roughly 100,000 tons is the estimate offered, accompanied by large cruisers to cover tasks that too few giant battleships could perform. Experiments with 20-inch or 22-inch guns are considered likely, but their slow rate of fire would make aiming difficult and could favour a return to 18-inch weapons. More equipment, power and personnel also enlarge ships, while retaining skilled crews increases pressure for better accommodation.
