Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Nikon S4100 and Nikon S6100 side-by-side from the front, back and top in their relative dimensions. Nikon S4100 has external dimensions of 95 x 57 x 20 mm (3.74 x 2.24 x 0.79″) and weighs (including batteries). Nikon S6100 has external dimensions of 98 x 58 x 27 mm (3.86 x 2.28 x 1.06″) and weighs 175 g (0.39 lb / 6.17 oz) (including batteries).

Now lets look at the top view comparison of Nikon S4100 and Nikon S6100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S4100 is 175g lighter than the Nikon S6100 but we don't think this will make a significant difference.
