Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon D80 and Fujifilm XP150 side-by-side from the front, back and top in their relative dimensions. Nikon D80 has external dimensions of 132 x 103 x 77 mm (5.2 x 4.06 x 3.03″) and weighs 668 g (1.47 lb / 23.56 oz) (including batteries). Fujifilm XP150 has external dimensions of 103 x 71 x 27 mm (4.06 x 2.8 x 1.06″) and weighs 205 g (0.45 lb / 7.23 oz) (including batteries).
Below you can see the front view size comparison of Nikon D80 and Fujifilm XP150. Fujifilm XP150 is clearly the smaller of the two cameras. Its body is 29mm narrower, 32mm shorter and 50mm thinner than Nikon D80. As you can tell, actually this is not a fair size comparison since Fujifilm XP150 has a built-in lens but Nikon D80 doesn't. Once you put a lens on D80, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Fujifilm XP150 is significantly lighter (463g ) than the Nikon D80 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on D80, the total kit will weigh much higher.
