Using the right image size on your website is important for a number of reasons. Properly sized images can improve your website’s performance and reduce load times, which can help to improve the user experience. They can also help to ensure that your website looks its best on a variety of devices and screen sizes.
In 2023, it is recommended to use responsive images that can adjust to the size of the device they are being viewed on. This can be achieved using the srcset
and sizes
attributes in the img
tag. The srcset
attribute allows you to specify a set of images with different sizes and the sizes
attribute allows you to specify the size of the image in relation to the viewport.
For example:
<img src=”small.jpg” srcset=”medium.jpg 1000w, large.jpg 2000w” sizes=”(max-width: 1000px) 100vw, 1000px” alt=”A responsive image”>
In this example, the browser will choose the appropriate image from the srcset
based on the size of the viewport and the designated sizes
.
In general, it is recommended to use images that are no larger than necessary, as larger images will take longer to load and can slow down your website. A good rule of thumb is to use images that are no larger than 1000 pixels in width or height.
In addition to using responsive images, it is also a good idea to optimize your images for the web by compressing them. There are a variety of tools available for image compression, including online tools such as TinyPNG and local tools such as Adobe Photoshop.
By following these best practices, you can ensure that your website uses the best image sizes and that your images are optimized for the web, resulting in a faster, more efficient website that provides a better user experience.
