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 S4100 and Canon 1200D 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). Canon 1200D has external dimensions of 130 x 100 x 78 mm (5.12 x 3.94 x 3.07″) and weighs 480 g (1.06 lb / 16.93 oz) (including batteries).
Below you can see the front view size comparison of Nikon S4100 and Canon 1200D. Nikon S4100 is clearly the smaller of the two cameras. Its body is 35mm narrower, 43mm shorter and 58mm thinner than Canon 1200D. As you can tell, actually this is not a fair size comparison since Nikon S4100 has a built-in lens but Canon 1200D doesn't. Once you put a lens on 1200D, 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 S4100 is 480g lighter than the Canon 1200D but we don't think this will make a significant difference.
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 1200D, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Nikon Coolpix S4100 nor Canon EOS 1200D (EOS Rebel T5 / EOS Kiss X70) provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon S4100 and Canon 1200D's LCD screens has the same diagonal size of 3".
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
