How to Find the Height and Width of an Image in Python

In this article, we show how to find the height and width of an image in Python.

Knowing the height and width is very important because there are so useful things that can be done with the width and height, such as calculating where to put certain things on the image or calculating its center.

To find the height and width of an image in Python, we use the following line, height, width= image.shape[:2]

where image is the image of the shape that you want to find the height and width for

You can then take these height and width variables and make calculations, so as to determine the positioning of various things

Below is the full code of a program that finds the height and width of an image and prints out the height and width values.

import cv2 image= cv2.imread('House.png') height, width= image.shape[:2] print("The height is ", height) print("The width is ", width)

First we import the cv2 module because we use this module to read in the image.

We create a variable, image, that we read in an image through using the cv2.imread() function.

We then read in the height and width using the shape attribute.

We then print out the height and width values.

And this is how we can find the height and width of an image in Python.
