What is PT or Points used in Typography / Web Design
In typography, the point ( PT) is the smallest unit of measure. It is used for measuring font size, leading, and other items on a printed page. The size of the point has varied throughout the history of printing. Since the 18th century, the point’s size has varied from 0.18 to 0.4 millimeters. Source
What is PX or Pixel used in Typography / Web Design
A pixel (px) at 96DPI (dots per inch) is equal to 0.2645835 millimeters, 0.010416675 inches, or 0.75 point. It is a measurement of how tall a font is in pixels which are visible on your computer screen. So, if a font is 12 pixels in height, that means it takes up 12 pixels on your screen from the top of the letter, to the bottom, which also includes the characters that have sections which are under the guide line, such as a “p” character.
