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 S9100 and Nikon 1 AW1 side-by-side from the front, back and top in their relative dimensions. Nikon S9100 has external dimensions of 105 x 62 x 35 mm (4.13 x 2.44 x 1.38″) and weighs 214 g (0.47 lb / 7.55 oz) (including batteries). Nikon 1 AW1 has external dimensions of 114 x 72 x 37 mm (4.47 x 2.81 x 1.46″) and weighs 356 g (0.78 lb / 12.6 oz) (including batteries).
Below you can see the front view size comparison of Nikon S9100 and Nikon 1 AW1. Nikon S9100 is clearly the smaller of the two cameras. Its body is 9mm narrower, 10mm shorter and 2mm thinner than Nikon 1 AW1. As you can tell, actually this is not a fair size comparison since Nikon S9100 has a built-in lens but Nikon 1 AW1 doesn't. Once you put a lens on 1 AW1, its thickness will increase significantly.
Here is the back view size comparison of Nikon S9100 and Nikon 1 AW1.
Now lets look at the top view comparison of Nikon S9100 and Nikon 1 AW1.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon S9100 is significantly lighter (142g ) than the Nikon 1 AW1 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 1 AW1, the total kit will weigh much higher.
