How does ship makers know how much weight a ship can hold?

Buoyancy. F=ρVg; Force (buoyancy) = density of the fluid * displaced volume * gravity. For this example, let’s assume the density of the water and gravity are constant. (IRL salt content and temperature can change density, also fun fact gravity isn’t constant everywhere on earth so that can change too…) That means the volume of displaced water is the variable that can be changed to determine the capacity of a ship. By designing a ship to displace more volume it can carry more.
Edit: formatting & added note about constants aren’t actually constant based on reply.

They calculate the volume of water that a ship displaces when it is empty, and the volume of water that it displaces when at its maximum safe displacement. The mass of the volume of water which makes up the difference is the maximum load the ship can carry.
