Here is a method that returns the image dimensions   from PIL import Image import os  def get image dimensions imagefile               Helper function that returns the image dimentions       param  imagefile str  path to image       return dict  of the form   width  lt int gt   height  lt int gt   size bytes  lt size bytes gt                 Inline import for PIL because it is not a common library     with Image open imagefile  as img            Calculate the width and hight of an image         width  height   img size        calculat ethe size in bytes     size bytes   os path getsize imagefile       return dict width width  height height  size bytes size bytes

For me the easiest way is to take all the values returned by image shape   height  width  channels   img shape   if you don t want the number of channels  useful to determine if the image is bgr or grayscale  just drop the value   height  width      img shape

I use numpy size   to do the same   import numpy as np import cv2  image   cv2 imread  image jpg   height   np size image  0  width   np size image  1

You can use image shape to get the dimensions of the image  It returns 3 values  First value is width of an image  second is height and last one is channel  You dont need last value here so you can use below code to get height and width of image  width  height   src shape  2  lt br gt  print width  height

Use the function GetSize from the module cv with your image as parameter  It returns width  height as a tuple with 2 elements   width  height   cv GetSize src

Using openCV and numpy it is as easy as this   import cv2  img   cv2 imread  path to img  0  height  width   img shape  2

I believe simply img shape -1  -1  would be nicer
