Which resolution value is commonly used for web or on-screen graphics?

• A. 72 ppi
• B. 600 dpi
• C. 150 ppi
• D. 300 dpi

Answer: (A)

Web graphics are displayed as pixels on screens, so the practical concern is how many pixels the image contains rather than how many dots per inch it would print at. The convention of 72 ppi comes from older screen standards and aligns with how displays map pixels to on-screen size, keeping file sizes reasonable while preserving detail at typical screen viewing distances. Higher printing-focused values like 300 or 600 dpi don’t affect on-screen sharpness and just inflate file sizes for web use. A middle ground like 150 ppi isn’t a standard target for web graphics. So, 72 ppi is the standard choice for web or on-screen graphics.
