How To Resize Images Proportionally Keeping The Aspect Ratio

Are you struggling with resizing images while keeping their aspect ratio intact? Don't worry! In this article, we are going to walk you through the steps to resize images proportionally without distorting their original aspect ratio.

Resizing images can be a common task, especially when working on web development or graphic design projects. It's important to resize images proportionally to ensure they look good and maintain their clarity. Resizing images without maintaining the aspect ratio can lead to distorted or stretched images, which is less than ideal.

One of the ways to resize images proportionally is by using code. You can achieve this by calculating the aspect ratio of the original image and then resizing it accordingly. Let's dive into the steps to resize images while keeping the aspect ratio intact.

Step 1: Calculate the Aspect Ratio

Before resizing the image, you need to calculate the aspect ratio of the original image. The aspect ratio is the ratio of the width to the height of the image. You can calculate it by dividing the width of the image by its height.

aspectRatio = originalWidth / originalHeight

Step 2: Determine the New Width or Height

Once you have calculated the aspect ratio of the original image, you can determine the new width or height based on the desired size you want the image to be. If you want to resize the image to a new width, you can calculate the new height by multiplying the new width by the aspect ratio.

newHeight = newWidth / aspectRatio

Similarly, if you want to resize the image to a new height, you can calculate the new width by multiplying the new height by the aspect ratio.

newWidth = newHeight * aspectRatio

Step 3: Resize the Image Using Code

Now that you have calculated the new width or height based on the aspect ratio, you can resize the image using code. There are various programming languages and libraries that you can use to resize images, such as Python, JavaScript, or PHP.

For example, in Python using the PIL library, you can resize an image while keeping the aspect ratio intact with the following code snippet:

from PIL import Image

def resize_image(image_path, new_width):
    image = Image.open(image_path)
    original_width, original_height = image.size

    aspect_ratio = original_width / original_height
    new_height = int(new_width / aspect_ratio)

    resized_image = image.resize((new_width, new_height))
    resized_image.save("resized_image.jpg")

resize_image("original_image.jpg", 300)

By following these steps and using the code snippet provided, you can easily resize images proportionally while maintaining their aspect ratio. Remember, it's important to preserve the aspect ratio of images to ensure they display correctly and look visually appealing in your projects.
