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 A6500 and Sony RX10 IV side-by-side from the front, back and top in their relative dimensions. Sony A6500 has external dimensions of 120 x 67 x 53 mm (4.72 x 2.64 x 2.09″) and weighs 453 g (1.00 lb / 15.98 oz) (including batteries). Sony RX10 IV has external dimensions of 133 x 94 x 145 mm (5.24 x 3.7 x 5.71″) and weighs 1095 g (2.41 lb / 38.62 oz) (including batteries).
Below you can see the front-view size comparison of the Sony A6500 and the Sony RX10 IV. Sony A6500 is clearly the smaller of the two cameras. Its body is 13mm narrower, 27mm shorter and 92mm thinner than Sony RX10 IV. As you can tell, actually this is not a fair size comparison since Sony RX10 IV has a built-in lens but Sony A6500 doesn't. Once you put a lens on A6500, its thickness will increase significantly.
Here is the back view size comparison of the Sony A6500 and Sony RX10 IV.
Now lets look at the top view comparison of Sony A6500 and Sony RX10 IV.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony A6500 is significantly lighter (642g ) than the Sony RX10 IV which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on A6500, the total kit will weigh much higher.
