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 S6100 and Canon A1400 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 A1400 has external dimensions of 95 x 62 x 30 mm (3.74 x 2.44 x 1.18″) and weighs 174 g (0.38 lb / 6.14 oz) (including batteries).
Below you can see the front-view size comparison of the Nikon S6100 and the Canon A1400. Nikon S6100 is 4mm shorter and 3mm thinner than Canon A1400 but it is also 3mm wider.
Here is the back view size comparison of the Nikon S6100 and Canon A1400.
Now lets look at the top view comparison of Nikon S6100 and Canon A1400.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A1400 is 1g lighter than the Nikon S6100 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix S6100 nor Canon PowerShot A1400 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon S6100's 3.00" LCD screen is slightly larger than Canon A1400's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
