When creating web images, important factors to consider are the image size, resolution, and aspect ratio.
The maximum width of an image is 1920 px, while 768 px is crucial for mobile optimization. Common aspect ratios include 16:9 (monitor), 1:1 (social media), and 1:1.618 (golden ratio).
Web Image Size Guide
The width of web images is as follows:
- Maximum width: 1920 px (Full HD resolution)
- Optimized for fixed width: 1280 px (optimized for desktop view)

The height is not strictly limited due to scrolling, but maintaining a standard aspect ratio is recommended.

Latest Web Image Trends and Optimization Strategies
According to the latest web image trends, implementing responsive images using the CSS srcset attribute is essential. This feature allows support for various screen sizes and maintains image quality on high-resolution devices.
Additionally, converting images to Google's WebP format is highly recommended for reducing file sizes. WebP offers smaller file sizes while maintaining high quality compared to JPEG or PNG.
Defining image dimensions in pixels (px) significantly contributes to optimizing web page loading speeds, while maintaining the aspect ratio prevents distortion. Lastly, the resolution, measured in DPI (dots per inch) or PPI (pixels per inch), plays a crucial role in image quality. While 72 DPI is standard for web images, higher resolutions, such as 150 DPI or above, are increasingly used for high-resolution screens.
