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 Samsung TL225 and Nikon S6100 side-by-side from the front, back and top in their relative dimensions. Samsung TL225 has external dimensions of 100 x 60 x 19 mm (3.94 x 2.36 x 0.75″) and weighs 187 g (0.41 lb / 6.60 oz) (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).
Below you can see the front-view size comparison of the Samsung TL225 and the Nikon S6100. Nikon S6100 is 2mm narrower and 2mm shorter than Samsung TL225 but it is also 8mm thicker.
Here is the back view size comparison of the Samsung TL225 and Nikon S6100.
Now lets look at the top view comparison of Samsung TL225 and Nikon S6100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon S6100 is 12g lighter than the Samsung TL225 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Samsung TL225 (ST550) nor Nikon Coolpix S6100 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors. If weather sealing is a must-have feature for you, check these sections: Top Compact Cameras with Weather Sealing
LCD Screen Size and Features
Samsung TL225's 3.50" LCD screen is slightly larger than Nikon S6100's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
