Why PPI Matters for Screen Measurement
PPI (Pixels Per Inch) determines how large each pixel appears on your screen. The ThinkPad X1 Carbon Gen 13's 243 PPI means 243 tiny dots fit within one physical inch of screen space. A higher PPI means smaller pixels, sharper text, and more precise ruler markings.
For comparison, a typical desktop monitor has around 96 PPI, while the ThinkPad X1 Carbon Gen 13 at 243 PPI offers 2.5x the pixel density. This higher density allows the on-screen ruler to display finer graduation marks and more accurate measurements.
