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 Sony a5000 and Olympus E-PL6 side-by-side from the front, back and top in their relative dimensions. Sony a5000 has external dimensions of 110 x 63 x 36 mm (4.33 x 2.48 x 1.42″) and weighs 269 g (0.59 lb / 9.49 oz) (including batteries). 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).
Below you can see the front-view size comparison of the Sony a5000 and the Olympus E-PL6. Sony a5000 is clearly the smaller of the two cameras. Its body is 1mm narrower, 1mm shorter and 2mm thinner than Olympus E-PL6.
Here is the back view size comparison of the Sony a5000 and Olympus E-PL6.
Now lets look at the top view comparison of Sony a5000 and Olympus E-PL6.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony a5000 is significantly lighter (56g ) than the Olympus E-PL6 which may become a big advantage especially on long walking trips.
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 Sony a5000 has an APS-C sized sensor and Olympus E-PL6 has a smaller Four Thirds sensor, Olympus E-PL6's lenses for a similar focal length and aperture will generally be lighter and smaller than the Sony a5000 lenses.
Weather Sealing
Unfortunately neither the Sony Alpha a5000 nor Olympus PEN E-PL6 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
Sony a5000 and Olympus E-PL6's LCD screens have the same diagonal size of 3.00 inches.

Tilting screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels.
