Proposed dimensions for the treasure ships vary enormously, raising the question of whether a conventional junk form could have been scaled to the largest claimed sizes. The uncertainty also involves reported fleet strengths, large crews, the voyages to Africa, and historical units of measurement whose length varied by place and time. A surviving example would let historians test those claims against the structure, rigging, and capacity of the vessel itself. Written accounts and modern reconstructions cannot settle the issue on their own.

Zheng He's treasure ships and the problem of scale
The scale, rig, and construction of Zheng He's treasure ships remain contested because the surviving evidence does not settle what the great voyages required.
