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 HX90V and Sony W550 side-by-side from the front, back and top in their relative dimensions. Sony HX90V has external dimensions of 102 x 58 x 36 mm (4.02 x 2.28 x 1.42″) and weighs 245 g (0.54 lb / 8.64 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony W550 is significantly lighter (135g ) than the Sony HX90V which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-HX90V nor Sony Cyber-shot DSC-W550 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 HX90V and Sony W550's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony HX90V features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Sony W550 has a fixed type screen which provides less flexibility in shooting positions compared to HX90V.
