How To Resize Image In Css

Resizing images is a common task in web design, and there are many ways to accomplish this goal. In this blog post, we will cover how to resize images using CSS, which is a powerful and flexible way to control the appearance of your website.

1. Using Width and Height Properties

The easiest way to resize an image in CSS is by using the width and height properties. These properties allow you to set a specific size for an image, either in pixels or as a percentage of its container.

For example, here’s how you could set the width of an image to 200 pixels and its height to 100 pixels:

    img {
        width: 200px;
        height: 100px;

Alternatively, you can set the width and height as percentages of the container:

    img {
        width: 50%;
        height: 25%;

2. Using the max-width and max-height Properties

If you want to set a maximum size for an image but allow it to scale down when the container is smaller, you can use the max-width and max-height properties. This ensures that the image will not exceed the specified dimensions, but it will still scale down to fit its container if necessary.

Here’s an example:

    img {
        max-width: 100%;
        max-height: 50%;

3. Using the object-fit Property

The object-fit property is a more advanced way to handle resizing images in CSS. It allows you to control how the image should be scaled and positioned within its container. The available values for this property are:

  • fill (default) – The image is stretched to fill the container, possibly distorting its aspect ratio.
  • contain – The image is scaled to fit its container while maintaining its aspect ratio. It will be displayed entirely, possibly with some empty space around it.
  • cover – The image is scaled to cover its container while maintaining its aspect ratio. The image will be cropped if necessary to ensure there are no empty spaces.
  • none – The image is not resized and retains its original size.
  • scale-down – The image is scaled down to fit its container, but only if it would otherwise be larger than its original size.

For example, to make an image cover its container while maintaining its aspect ratio, you can use the following CSS:

    img {
        width: 100%;
        height: 100%;
        object-fit: cover;


Resizing images in CSS is easy and flexible with the various properties and techniques available. Whether you want to set a specific size, constrain the maximum size, or control how the image scales within its container, CSS has you covered. Experiment with these techniques to achieve the perfect look for your website.
