What is a Light Year and a Point (Typography)?
A light-year is a unit of astronomical distance equal to the distance that light travels in one Julian year in a vacuum (approximately 9.461 trillion kilometers or 5.879 trillion miles).
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 Light Year 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 Light Year and Point (Typography)
The concept was first used by Friedrich Bessel in 1838 when measuring the distance to the star 61 Cygni.
Typographic points evolved from historical printing practices. The DTP point standardized previous variations for digital use.

Frequently Asked Questions
Questions About Light Year (ly)
Is a light-year a unit of time or distance?
A light-year (ly) is a unit of distance, not time. It represents the distance light travels in one year.
How far is a light-year in kilometers and miles?
One light-year is approximately 9.461 trillion kilometers (9.461 x 10^12 km) or 5.879 trillion miles (5.879 x 10^12 mi).
What is the closest star to Earth in light-years?
Excluding the Sun, the closest star system to Earth is Alpha Centauri, which is about 4.37 light-years away.
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.
