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 S9100 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 S9100 has external dimensions of 105 x 62 x 35 mm (4.13 x 2.44 x 1.38″) and weighs 214 g (0.47 lb / 7.55 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung TL225 and the Nikon S9100. Samsung TL225 is clearly the smaller of the two cameras. Its body is 5mm narrower, 2mm shorter and 16mm thinner than Nikon S9100.
Here is the back view size comparison of the Samsung TL225 and Nikon S9100.
Now lets look at the top view comparison of Samsung TL225 and Nikon S9100.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung TL225 is 27g lighter than the Nikon S9100 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Samsung TL225 (ST550) nor Nikon Coolpix S9100 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
Samsung TL225's 3.50" LCD screen is slightly larger than Nikon S9100's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
