Calculate pixels per inch from any display's resolution and screen size. Also shows pixel pitch, total megapixels, aspect ratio, physical dimensions, and the retina viewing distance where pixels become invisible to the human eye. Works for monitors, laptops, phones, tablets, and TVs.
| PPI range | Typical devices | Best use |
|---|---|---|
| Under 100 | Large TVs, 27" 1080p monitors | Gaming from distance, couch viewing. |
| 100-150 | 1440p monitors, standard laptops | Desktop use, PC gaming, office tasks. |
| 150-250 | 4K monitors, premium laptops | Text clarity, coding, creative work. |
| 250-400 | Tablets, high-end laptops | Close viewing with crisp text and UI. |
| 400+ | Smartphones, VR displays | Very close proximity viewing. |
PPI means pixels per inch — how many pixels are packed into one inch of display. Higher PPI means sharper text and images at the same viewing distance.
Not always. Higher PPI improves sharpness but requires more GPU power and OS scaling. The extra detail may not be visible from farther viewing distances.
Most gaming monitors sit around 90-140 PPI. A 24" 1080p monitor is ~92 PPI, while a 27" 1440p monitor is ~109 PPI.
