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 a3500 and Canon A2300 side-by-side from the front, back and top in their relative dimensions. Sony a3500 has external dimensions of 128 x 91 x 85 mm (5.04 x 3.58 x 3.35″) and weighs 411 g (0.91 lb / 14.50 oz) (including batteries). Canon A2300 has external dimensions of 95 x 54 x 20 mm (3.74 x 2.13 x 0.79″) and weighs 125 g (0.28 lb / 4.41 oz) (including batteries).
Below you can see the front-view size comparison of the Sony a3500 and the Canon A2300. Canon A2300 is clearly the smaller of the two cameras. Its body is 33mm narrower, 37mm shorter and 65mm thinner than Sony a3500. As you can tell, actually this is not a fair size comparison since Canon A2300 has a built-in lens but Sony a3500 doesn't. Once you put a lens on a3500, its thickness will increase significantly.
Now lets look at the top view comparison of Sony a3500 and Canon A2300.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon A2300 is significantly lighter (286g ) than the Sony a3500 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 a3500, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Sony Alpha a3500 nor Canon PowerShot A2300 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 a3500's 3.00" LCD screen is slightly larger than Canon A2300's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
