What is resolution?

Generally, in GCSE Computer Science, resolution is defined as the total number of pixels that make up a digital image. The more pixels you have (higher resolution), the more detailed and sharper the image will be. You can calculate the resolution by multiplying the image's width by its height in pixels.

However, some exam boards may ask you to use a different term to mean the same thing. Explore our revision notes for AQA GCSE Computer Science where the term resolution is replaced with image size.

Imagine your computer screen is like a grid, and each tiny square in that grid is a pixel. Resolution (image size) tells you how many of those tiny squares are used to create the image.
