Height in inches is calculated as which?

• A. Pixel height divided by image ppi
• B. Pixel height times image ppi
• C. Pixel width divided by image ppi
• D. Pixel height plus image ppi

Answer: (A)

Converting pixel dimensions to physical size uses division by pixel density. Height in inches equals the pixel height divided by the image’s pixels-per-inch (PPI). For example, 1200 pixels at 300 PPI gives 1200 ÷ 300 = 4 inches. Why the other options don’t fit: multiplying the pixel height by PPI would yield a unit that doesn’t represent a length in inches, mixing pixels with density in a way that doesn’t convert to physical size. Adding the pixel height to PPI also mixes incompatible units. Using the pixel width would give the horizontal dimension, not the vertical one.
