A set of Font Metrics cards contains the main metrics of the symbol Q in different fonts and can be useful in the font design process. A font designer can compare metrics of several well-known fonts without switching between several tabs of a font program. The concept is applicable to round letters (Q, O, G, C), but can be extended to a series of sets for other symbols.

The front side of the cards shows values for the height, width, and stress of the symbol, as well as information about how far the lower extruder descends from the baseline and how far it goes beyond the circle to the right or left. The back of the cards features the font.
