About the Unit

Point (pt): The point (pt) is a traditional typographic unit commonly used in print, and one of the standard measurement units in printed documents. 1pt is equal to 1/72 of an inch. Although pt is a physical unit and is not very common in digital design, it still has its use, especially when working with documents intended for print or when consistency is needed between digital and printed design. In CSS, using pt to define font size or other layout elements can be useful in print contexts, but its accuracy on digital screens may be affected by the screen's resolution. To ensure typography looks the same across devices, using relative units like em or rem may be more appropriate, but pt still has its place in document design, such as PDFs or other printed media formats.

Pro Tip: pt → em

Convert pt to em for text that adapts to the parent element’s font size.
