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 E-PL6 and Olympus E-PL3 side-by-side from the front, back and top in their relative dimensions. Olympus E-PL6 has external dimensions of 111 x 64 x 38 mm (4.37 x 2.52 x 1.5″) and weighs 325 g (0.72 lb / 11.46 oz) (including batteries). Olympus E-PL3 has external dimensions of 110 x 64 x 37 mm (4.33 x 2.52 x 1.46″) and weighs 313 g (0.69 lb / 11.04 oz) (including batteries).
Below you can see the front-view size comparison of the Olympus E-PL6 and the Olympus E-PL3. Olympus E-PL6 has the same height with Olympus E-PL3. On the other hand, with a width of 111mm, it is 1 wider and also with a thickness of 38mm, it is 1mm thicker than Olympus E-PL3.
Here is the back view size comparison of the Olympus E-PL6 and Olympus E-PL3.
Now lets look at the top view comparison of Olympus E-PL6 and Olympus E-PL3.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Olympus E-PL3 is 12g lighter than the Olympus E-PL6 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Olympus E-PL6 and Olympus E-PL3 have the same Micro Four Thirds lens mount and Four Thirds sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Olympus PEN E-PL6 nor Olympus PEN E-PL3 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
Olympus E-PL6 and Olympus E-PL3's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
