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 Olympus TG-870 and Olympus TG-820 iHS side-by-side from the front, back and top in their relative dimensions. Olympus TG-870 has external dimensions of 113 x 64 x 28 mm (4.45 x 2.52 x 1.1″) and weighs 221 g (0.49 lb / 7.80 oz) (including batteries). Olympus TG-820 iHS has external dimensions of 101 x 65 x 26 mm (3.98 x 2.56 x 1.02″) and weighs 206 g (0.45 lb / 7.27 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus TG-870 and the Olympus TG-820 iHS. Olympus TG-820 iHS is 12mm narrower and 2mm thinner than Olympus TG-870 but it is also 1mm taller.
Here is the back view size comparison of the Olympus TG-870 and Olympus TG-820 iHS.
Now lets look at the top view comparison of Olympus TG-870 and Olympus TG-820 iHS.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus TG-820 iHS is 15g lighter than the Olympus TG-870 but we don't think this will make a significant difference.

LCD Screen Size and Features
Olympus TG-870 and Olympus TG-820 iHS's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Olympus TG-870 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Olympus TG-820 iHS has a fixed type screen which provides less flexibility in shooting positions compared to TG-870.
