Question: 1 / 400

What does 'dpi' stand for, and why is it significant in graphic design?

Dots per inch; it measures image resolution, influencing print quality

'DPI' stands for "dots per inch," and it is significant in graphic design because it measures the resolution of an image. Understanding DPI is essential for achieving the desired print quality; higher DPI values generally indicate more detail and clarity in an image when printed. For instance, images intended for high-quality print work, such as brochures or posters, typically require a DPI of 300 or more, as this level of detail ensures sharp and professional-looking prints.

In contrast, images that will be displayed online do not require as high a DPI—usually around 72 DPI is sufficient because screens display images differently than printers. Therefore, knowing how to manage DPI settings allows designers to optimize images for specific mediums, ensuring that visual content appears as intended, whether in print or on a digital platform.
