The design, position and size of a dormer really depends on two factors:
1. Which elevation the dormer is to be positioned on - Front, Side or Rear.
2. What you are aspiring to achieve by introducing a dormer. Do you require more floor area or head room, or is it simply that you don't like roof lights and you need to allow the natural transmission of light.
A box type dormer offers by far more useable floor area and head height than any other type. A hipped or gable style dormer affects the useable floor area & head height, and the width of a gable or hipped dormer also affects the pitch and height of the roof ridge. This is normally dictated by the existing ridge line - remember the wider the dormer, the higher the ridge. Dormers can be all different shapes and sizes, below are just a few examples (click to enlarge).
This style of dormer is more attractive if built correctly, using the right materials (reclaimed if possible), not having the dormers too large and positioned as previously mentioned. It tends to blend in much better with the roof scene, but this style does reduce the usable floor space. The width of this style is dictated by the existing ridge height. The wider the dormer the higher the ridge (click to enlarge).
This style of dormer relates to the hipped dormer (fig 2). By incorporating an arch or curve it allows the appearance to blend in more naturally roof scene, but again it reduces the head height and usable floor area (click to enlarge).
Usually a large gable style dormer is added to the side elevation to achieve maximum floor area and head height required for the stairs. A normal combination would be a side elevation gable or barn hip and a full rear elevation box style dormer. In some instances you would have to consider building a dormer to the side elevation to allow for the head height required for your stairs (part K of the current building regulations) to provide access to the loft (click to enlarge).
