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 S6100 and Canon 70D side-by-side from the front, back and top in their relative dimensions. 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). Canon 70D has external dimensions of 139 x 104 x 79 mm (5.47 x 4.11 x 3.09″) and weighs 755 g (1.66 lb / 26.63 oz) (including batteries).
Below you can see the front view size comparison of Nikon S6100 and Canon 70D. Nikon S6100 is clearly the smaller of the two cameras. Its body is 41mm narrower, 46mm shorter and 52mm thinner than Canon 70D. As you can tell, actually this is not a fair size comparison since Nikon S6100 has a built-in lens but Canon 70D doesn't. Once you put a lens on 70D, 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.
Nikon S6100 is significantly lighter (580g ) than the Canon 70D 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 70D, the total kit will weigh much higher.
Weather Sealing
Thanks to the weather sealed body of 70D, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to S6100.
LCD Screen Size and Features
Nikon S6100 and Canon 70D's LCD screens has the same diagonal size of 3".
On the other hand, Canon 70D sports a
Fully Articulated screen which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. Nikon S6100's LCD screen is a fixed type which provides almost no flexibility in shooting positions compared to 70D.
