Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Canon SX30 IS and Sony WX300 side-by-side from the front, back and top in their relative dimensions. Canon SX30 IS has external dimensions of 123 x 92 x 108 mm (4.84 x 3.62 x 4.25″) and weighs 601 g (1.32 lb / 21.20 oz) (including batteries). Sony WX300 has external dimensions of 96 x 55 x 25 mm (3.78 x 2.16 x 0.98″) and weighs 166 g (0.37 lb / 5.86 oz) (including batteries).
Below you can see the front view size comparison of Canon SX30 IS and Sony WX300. Sony WX300 is clearly the smaller of the two cameras. Its body is 27mm narrower, 37mm shorter and 83mm thinner than Canon SX30 IS.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Sony WX300 is significantly lighter (435g ) than the Canon SX30 IS which may become a big advantage especially on long walking trips.
Unfortunately neither Canon PowerShot SX30 IS nor Sony Cyber-shot DSC-WX300 provides any type of weather sealing in their body, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Sony WX300's 3" LCD screen is slightly larger than Canon SX30 IS's 2.7" screen.
On the other hand, Canon SX30 IS sports a Fully Articulated screen
which you can change the angle and position of the screen almost freely, making it possible to shoot from waist or over the head levels, and especially very useful for shooting selfies and video. On the other hand, Sony WX300 has a fixed type screen which provides almost no flexibility in shooting positions compared to SX30 IS.
