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 Olympus E-M10 IV and Samsung ST95 side-by-side from the front, back and top in their relative dimensions. Olympus E-M10 IV has external dimensions of 122 x 84 x 49 mm (4.8 x 3.31 x 1.93″) and weighs 383 g (0.84 lb / 13.51 oz) (including batteries). Samsung ST95 has external dimensions of 92 x 53 x 17 mm (3.62 x 2.09 x 0.67″) and weighs (including batteries).
Below you can see the front view size comparison of Olympus E-M10 IV and Samsung ST95. Samsung ST95 is clearly the smaller of the two cameras. Its body is 30mm narrower, 31mm shorter and 32mm thinner than Olympus E-M10 IV. As you can tell, actually this is not a fair size comparison since Samsung ST95 has a built-in lens but Olympus E-M10 IV doesn't. Once you put a lens on E-M10 IV, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung ST95 is 383g lighter than the Olympus E-M10 IV but we don't think this will make a significant difference.
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 E-M10 IV, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither Olympus OM-D E-M10 IV nor Samsung ST95 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
Olympus E-M10 IV and Samsung ST95's LCD screens has the same diagonal size of 3.00".
On the other hand, Olympus E-M10 IV 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 Samsung ST95 has a fixed type screen which provides less flexibility in shooting positions compared to E-M10 IV.
