False. Different fonts with the same point sizes can vary in their actual height. The height of a font depends on various factors, including the design and proportions of the specific font. Different fonts may have different x-heights (the height of lowercase letters), ascenders (the parts of lowercase letters that extend above the x-height), descenders (the parts of lowercase letters that extend below the baseline), and overall proportions, which can make them appear taller or shorter despite having the same point size.
