Frequently Asked Questions

What is the optimal PPI for a computer monitor?

For desktop monitors viewed at 20–28 inches (50–70 cm), 109–140 PPI is great without scaling (e.g. 27″ 1440p or 32″ 4K), while 218 PPI (e.g. 27″ 5K or 32″ 6K) provides true Retina sharpness with 2× integer scaling.

Why is 27-inch 4K sometimes controversial?

A 27-inch 4K monitor has 163 PPI. Text is too small at 100% native scaling and too large at 200% integer scaling, requiring fractional scaling (typically 150%) in Windows or non-integer macOS virtual scaling.

What is the difference between ultrawide and standard monitor PPI?

A 34-inch ultrawide 3440×1440 monitor has 110 PPI, which is virtually identical to a standard 27-inch 1440p (109 PPI). It offers 33% more horizontal width with the exact same pixel density.
