Frequently asked questions

What is PPI?

Pixels per inch: how many pixels fit in one inch of the screen. Higher PPI means sharper text and images.

Is higher PPI always better?

Only up to a point. From normal distance, phones look perfect around 400 PPI, laptops around 150 and TVs need far less because you sit further away.

What's the size of a 55-inch TV in cm?

A 16:9 55″ TV screen is about 122 × 68.5 cm (diagonal 139.7 cm). Pick the preset to see it.

Is PPI the same as DPI?

People often use them the same way. Strictly, DPI is for printers (ink dots) and PPI for screens (pixels).
