What is Resolution?

In web design, an image’s resolution tells you how many pixels it contains horizontally and vertically. Higher-resolution images tend to be more detailed, but they also have larger file sizes.

More About Resolution

Resolution is an essential concept in web design and computing in general. Every image that you see on the web has a set resolution. The images can be resized, but depending on their file type, the resolution that you choose can drastically impact image quality.

Every computing device with a screen also has a maximum resolution, which depends on the screen size. In computer screens and images, the resolution indicates how many pixels you can see both vertically and horizontally.

A greater resolution translates to higher-fidelity images, but those usually have larger file sizes. With a website, you want to use large image resolutions to show enough details, but not so much that you’re dealing with massive files.
