Working backwards always works better for me. For example, what is your favorite light?
How mush spread does your favorit light have? That shoudl give you an idea of aquarium display footprint.
For height...what corals do you plan on keeping and what type of flow do they thrive in? It its SPS, for example, you would want a wide angle, variable flow from pumps like Vortech, Tunze or even the Chinese Jebao. If so, there are certain dinesions these tanks are designed for. I would factor their recommendations.
Finally, other things to consider are: location, accessability, budget and owner's hands on involvement
