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 Canon SX540 HS and Samsung NX3000 side-by-side from the front, back and top in their relative dimensions. Canon SX540 HS has external dimensions of 120 x 82 x 92 mm (4.72 x 3.23 x 3.62″) and weighs 442 g (0.97 lb / 15.59 oz) (including batteries). Samsung NX3000 has external dimensions of 117 x 66 x 39 mm (4.61 x 2.6 x 1.54″) and weighs 230 g (including batteries).
Below you can see the front-view size comparison of the Canon SX540 HS and the Samsung NX3000. Samsung NX3000 is clearly the smaller of the two cameras. Its body is 3mm narrower, 16mm shorter and 53mm thinner than Canon SX540 HS. As you can tell, actually this is not a fair size comparison since Canon SX540 HS has a built-in lens but Samsung NX3000 doesn't. Once you put a lens on NX3000, its thickness will increase significantly.
Here is the back view size comparison of the Canon SX540 HS and Samsung NX3000.
Now lets look at the top view comparison of Canon SX540 HS and Samsung NX3000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung NX3000 is significantly lighter (212g ) than the Canon SX540 HS 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 NX3000, the total kit will weigh much higher.
Weather Sealing
Unfortunately neither the Canon PowerShot SX540 HS nor Samsung NX3000 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
Canon SX540 HS and Samsung NX3000's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Samsung NX3000 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 Canon SX540 HS has a fixed type screen which provides less flexibility in shooting positions compared to NX3000.
