Image and Video Resolution: Simple Definition

Resolution refers to the number of pixels (individual colored dots) that make up an image or video frame. A 1920x1080 resolution means 1920 pixels wide by 1080 pixels tall, totaling about 2 million pixels.

Higher resolution means more detail, but also larger file sizes. A 4K image (3840x2160) has 4 times more pixels than a 1080p image, so it requires roughly 4 times more storage.

Understanding Resolution

Resolution is often measured in total pixels (megapixels) for cameras, or by the height in lines for video. A 12-megapixel camera captures 12 million pixels per photo. “1080p” video has 1080 horizontal lines of pixels.

Screen resolution determines how sharp your display looks. A 4K monitor shows more pixels per inch than a 1080p monitor of the same size, resulting in sharper, more detailed images.
