Propeller diameter and blade length

How to set propeller diameter and blade length with the propellers 3D simulation software Heliciel:

The propeller diameter is the double of the radius at the blade tip . The propeller diameter determines the rotor swept area. Choosing the right diameter, and therefore the right blade length implies a knowledge of the role played by the surface of the propeller in the system.

In the software HELICIEL The propeller blade length is determined by the user in blade geometry tab> blade dimensions

propeller diameter and blade length

To make it simple, we could say that longer the propeller is, the better it is! But why, and upto which limit.? We usually come to the conclusion that longer the propeller is , better is the efficiency, but the length of the blade generates stresses that must be taken into account.
