IMAGE DIMENSIONS GUIDE

Images are an integral part of the internet, and they play a crucial role in enhancing the user experience. They are used to convey information, set the tone, and evoke emotions. However, using too many images or large images can slow down the loading time of a web page, resulting in a poor user experience. Therefore, compressing images for optimal speed is essential.
Compressing images involves reducing the file size of an image without compromising its quality. This can be achieved in various ways, such as using image compression software, reducing the image's dimensions, or reducing the color depth. Compressing images not only improves the loading time of a web page, but it also reduces the bandwidth usage, which is particularly important for users with slower internet connections.
Optimizing images for the web is a best practice that web developers and designers should follow. It can significantly improve the performance of a website, especially on mobile devices, where data usage is limited. It is important to strike a balance between image quality and file size. A website with high-quality images that are not optimized for the web can result in slow loading times, which can lead to a high bounce rate and a negative impact on search engine rankings.
Guidelines:
For desktop images, the recommended dimensions are typically between 1200-2000 pixels wide and 800-1200 pixels high. This size range provides a good balance between image quality and file size. It is also important to consider the aspect ratio of the image to ensure that it fits well within the design of the website.
For mobile images, the recommended dimensions are typically between 640-1000 pixels wide and 400-800 pixels high. Mobile devices have smaller screens, and images that are too large can slow down the loading time of a web page. It is also essential to consider the orientation of the image, as mobile devices can be used in portrait or landscape mode.
In addition to size considerations, it is also important to choose the appropriate file format for images. JPEG is the most commonly used format for photographs, while PNG is typically used for graphics and images with transparency. It is also important to compress images to reduce their file size without compromising their quality.
