You may sometimes be asked to provide your screen resolution, but you are not very technical and you do not want to search through the meanders of Windows or macOS settings…
Actually, it is not very complicated to retrieve this information in your computer settings, but I will suggest you a very simple solution to know the resolution of your screen !
Screen resolution is the number of dots or pixels that a screen can display. This number is defined by the number of horizontal pixels multiplied by the number of vertical pixels. With my screen for example, this indicator returns the following measurements: 1920 x 1080. Concretely, this means that my screen has 1920 horizontal pixels and 1080 vertical pixels.
So to very simply obtain the definition of your screen, simply go to on this site which will instantly give you the resolution of the screen it is displayed on.
Rest assured, there is nothing to worry about this site knowing your screen resolution, because imagine that most current sites (so-called responsive or adaptive) need to know your screen resolution to display optimally!
This is also why this tool works even on mobile as you can see with this capture made on my iPhone:
