I answer with a question. What are your fixed parameters and variables ones?
Are you asking for the value of your initial estimate for wing loading during the conceptual/preliminary sizing and synthesis? If so you need to link it to the higher aircraft level response. Hat is what type of mission are you operating and how does that drive wing loading. The typical metric of high w/s and low T/W do not always lead to optimum aircraft design.
HI,
Peter pointed us towards the answer to this problem. The W/S will depend on the main function and performance of the aircraft - speed (cruise, on function, take-off, etc). As an illustration, a steady flight with low gust sensitivity would requires high W/S. But this would mean high take-off and landing speeds.
Meaning, there is no short answer to this question. Torenbeek do give a method to arrive at compromise best.

Dear Jabez,
Wing loading is a function of aircraft type and mission.
Wing loading and wing weight lead to wing area. An aircraft with a wing area which is smaller than the one needed cannot meet the performance requirements that have been set. If it is bigger, then the aircraft carries structural and fuel, due to the added drag, weight which is not necessary.
Experience indicates the flight phase which defines the right wing loading. When experience is lacking the wing loading for the different phases of flight of the specific type of aircraft is calculated and the lowest value is chosen.
