You could use PyMouse   To get the screen size just use the screen size   attribute   from pymouse import PyMouse m   PyMouse   a   m screen size     a will return a tuple   X  Y   where X is the horizontal position and Y is the vertical position   Link to function in documentation

Using Linux Instead of regexp take the first line and take out the current resolution values   Current resolution of display  0    gt  gt  gt  screen   os popen  xrandr -q -d  0   readlines   0   gt  gt  gt  print screen Screen 0  minimum 320 x 200  current 1920 x 1080  maximum 1920 x 1920  gt  gt  gt  width   screen split   7   gt  gt  gt  print width 1920  gt  gt  gt  height   screen split   9   -1   gt  gt  gt  print height 1080  gt  gt  gt  print  Current resolution is  s x  s     width height  Current resolution is 1920 x 1080   This was done on xrandr 1 3 5  I don t know if the output is different on other versions  but this should make it easy to figure out

A lot of these answers use tkinter to find the screen height width  resolution   but sometimes it is necessary to know the dpi of your screen cross-platform compatible  This answer is from this link and left as a comment on another post  but it took hours of searching to find  I have not had any issues with it yet  but please let me know if it does not work on your system  import tkinter root   tkinter Tk   dpi   root winfo fpixels  1i    The documentation for this says  winfo fpixels number    Return the number of pixels for the given distance NUMBER  e g   quot 3c quot   as float  A distance number is a digit followed by a unit  so 3c means 3 centimeters  and the function gives the number of pixels on 3 centimeters of the screen  as found here   So to get dpi  we ask the function for the number of pixels in 1 inch of screen   quot 1i quot

Old question but this is missing   I m new to python so please tell me if this is a  bad  solution  This solution is supported for Windows and MacOS only and it works just for the main screen - but the os is not mentioned in the question    Measure the size by taking a screenshot  As the screensize should not change this has to be done only once  There are more elegant solutions if you have a gui toolkit like GTK  wx      installed    see Pillow  pip install Pillow     from PIL import ImageGrab  img   ImageGrab grab   print  img size

In Windows  you can also use ctypes with GetSystemMetrics     import ctypes user32   ctypes windll user32 screensize   user32 GetSystemMetrics 0   user32 GetSystemMetrics 1    so that you don t need to install the pywin32 package  it doesn t need anything that doesn t come with Python itself   For multi-monitor setups  you can retrieve the combined width and height of the virtual monitor   import ctypes user32   ctypes windll user32 screensize   user32 GetSystemMetrics 78   user32 GetSystemMetrics 79
