What is a Digit and a Point (Typography)?
The Digit, also known as the finger or fingerbreadth, is an ancient, anthropomorphic unit of length, originally based on the breadth (width) of a human adult finger (typically the index finger). As a body-based unit, its value varied significantly depending on the person, time period, and culture.
Historically, it was often considered to be approximately 3/4 of an inch or about 1.9 centimeters (cm). In many systems, it formed a subdivision of larger units like the palm, span, or cubit. For example, it was common for:
- 4 digits = 1 palm
- 12 digits = 1 span (sometimes)
- 24 or 28 digits = 1 cubit (depending on the cubit definition)
A point is a unit of length used in typography. The desktop publishing point (DTP point or PostScript point) is defined as 1/72 of an international inch (approximately 0.3527 mm).
Note: The Digit is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Point (Typography) belongs to the imperial/US customary system.
History of the Digit and Point (Typography)
The digit is one of the oldest known units of measurement, used by ancient civilizations including the Egyptians, Mesopotamians, Greeks, Romans, and later across Europe. Its convenience stemmed from the ready availability of the human hand for estimation.
- Ancient Egypt: The digit (djeba) was a fundamental unit, with 28 digits forming the Royal Cubit.
- Ancient Rome: The Roman digit (digitus) was defined as 1/16 of a Roman foot, approximately 1.85 cm. Four digiti made a palmus (palm).
- Medieval England: The digit was often reckoned as 3/4 of an inch, derived from the barleycorn (3 barleycorns = 1 inch, 4 digits = 3 inches).
Due to its inherent variability and the rise of more standardized systems based on physical prototypes (like the yard or meter), the digit gradually fell out of practical use for trade and science, becoming largely obsolete by the early modern period.
Typographic points evolved from historical printing practices. The DTP point standardized previous variations for digital use.
Common Uses for digits and points
Explore the typical applications for both Digit (imperial/US) and Point (Typography) (imperial/US) to understand their common contexts.
Common Uses for digits
The digit is now obsolete for practical measurement but is encountered in:
- Historical Texts: Found in ancient and medieval documents describing dimensions of objects, buildings, or anatomical measurements.
- Archaeology & Anthropology: Used when interpreting historical measurements or comparing ancient systems.
- Figurative Language: Occasionally used informally to mean a very small distance ("just a digit more").
- Understanding Historical Units: Key to understanding the structure of ancient measurement systems (e.g., relationship to palm, cubit).
Common Uses for points
- Specifying font sizes
- Measuring line spacing (leading) and other typographic elements
Frequently Asked Questions
Questions About Digit (digit)
How long is a digit?
There is no single, precise value for the digit because it was based on human anatomy and varied by system. Common historical approximations include:
- Approximately 0.75 inches (in)
- Approximately 1.85 to 1.9 centimeters (cm)
- Often defined as 1/4 of a palm or 1/16 of a foot within specific historical systems.
What is the relation between a digit and a palm?
In many historical systems (like the Roman and often the English), 4 digits were considered equal to 1 palm (the width of the hand across the base of the fingers).
What is the relation between a digit and a cubit?
The relationship varied. For example:
- The Egyptian Royal Cubit contained 28 digits.
- The common Greek and Roman cubits often contained 24 digits.
Is the digit an SI unit?
No, the digit is not an SI unit. It is an ancient, non-standardized, anthropomorphic unit. The corresponding SI unit for length is the meter (m).
Is the digit still used today?
No, the digit is not used for any standard or practical measurements today. Its use is confined to historical study, interpretation of old texts, and occasional figurative speech.
Where does the name 'digit' come from?
The name comes from the Latin word digitus, which means "finger" or "toe". This reflects the unit's origin based on the width of a human finger.
About Point (Typography) (pt)
How many points are in an inch?
In modern desktop publishing, there are exactly 72 points (pt) in 1 inch (in).
What is the difference between a point and a pixel?
A point (pt) is a unit of physical length (1/72 inch), typically used for print. A pixel (px) is a unit of digital display resolution and its physical size can vary depending on the screen's pixel density (PPI).
What does 12 pt font mean?
It means the height of the font characters (specifically, the 'em square', which includes space above and below the letters) is 12 points, or 12/72 = 1/6th of an inch.
