Image and Display Calculators

Image and Display Calculators share one workflow: pick a ratio, check density, then scale pixel dimensions without silent distortion. Width and height drive every result.

• Aspect Ratio Calculator The Aspect Ratio Calculator reduces width and height to a whole-number ratio, reports the decimal form, and matches common display standards.
• PPI Calculator The PPI Calculator finds pixels per inch from screen resolution and diagonal size, plus PPcm, PPI squared and dot pitch.
• Image Resize Calculator The Image Resize Calculator scales pixel dimensions by width, height, percent, max side or fit-within box, and flags aspect-ratio drift from rounding.
