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 Canon A810 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). Canon A810 has external dimensions of 95 x 62 x 30 mm (3.74 x 2.44 x 1.18″) and weighs 171 g (0.38 lb / 6.03 oz) (including batteries).
Below you can see the front-view size comparison of the Samsung TL225 and the Canon A810. Samsung TL225 is 2mm shorter and 11mm thinner than Canon A810 but it is also 5mm wider.
Here is the back view size comparison of the Samsung TL225 and Canon A810.
Now lets look at the top view comparison of Samsung TL225 and Canon A810.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A810 is 16g 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 Canon PowerShot A810 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 Canon A810's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
