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 Pentax K-70 and Sony A6300 side-by-side from the front, back and top in their relative dimensions. Pentax K-70 has external dimensions of 126 x 93 x 74 mm (4.94 x 3.66 x 2.91″) and weighs 688 g (1.52 lb / 24.27 oz) (including batteries). Sony A6300 has external dimensions of 120 x 67 x 49 mm (4.72 x 2.64 x 1.93″) and weighs 404 g (0.89 lb / 14.25 oz) (including batteries).
Below you can see the front-view size comparison of the Pentax K-70 and the Sony A6300. Sony A6300 is clearly the smaller of the two cameras. Its body is 6mm narrower, 26mm shorter and 25mm thinner than Pentax K-70.
Here is the back view size comparison of the Pentax K-70 and Sony A6300.
Now lets look at the top view comparison of Pentax K-70 and Sony A6300.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6300 is significantly lighter (284g ) than the Pentax K-70 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 both Pentax K-70 and Sony A6300 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.

Both the K-70 and the A6300 have weather sealings in their bodies, making them resistant to water and dust.

Pentax K-70 and Sony A6300's LCD screens have the same diagonal size of 3.00 inches.
Sony A6300 features a
