What Is This Tool?
This converter transforms measurements from the computer point, a standard unit in digital typography, into millimeters, the SI unit for length. It is used to accurately translate font sizes and layout dimensions into physical lengths used in print and prepress.
How to Use This Tool?
-
Enter the value in point (computer) units you wish to convert.
-
Select the point (computer) as the source unit and millimeter [mm] as the target unit.
-
Click convert to get the equivalent length in millimeters.
Key Features
-
Converts digital typography points (PostScript standard) to millimeters.
-
Supports accurate translation of font sizes, line heights, and layout dimensions for print.
-
Simple and browser-based for quick unit translation.
-
Useful for designers and print professionals working with PDFs and CSS print styles.
Examples
-
12 point (computer) corresponds to approximately 4.23 mm.
-
36 point (computer) converts to around 12.7 mm.
Common Use Cases
-
Specifying font sizes and line heights in desktop publishing software.
-
Defining page and element sizes in PDF and PostScript print workflows.
-
Mapping typography dimensions to physical lengths for print layout and production.
Tips & Best Practices
-
Use this tool when needing precise physical measurements for typography-related print jobs.
-
Remember the conversion is based on the PostScript point standard (1/72 inch).
-
Check physical layouts in millimeters to ensure accurate print dimensions.
Limitations
-
The computer point used here differs from historical metal-type points and TeX points.
-
Conversion assumes the PostScript point standard of 1/72 inch.
-
Rounding and printing tolerances may affect precision; millimeters are better for physical layouts.
Frequently Asked Questions
-
What is a point (computer) in typography?
-
It is a digital typography unit equal to 1/72 of an international inch, used mainly for specifying font sizes and layout dimensions.
-
Why convert points to millimeters?
-
Converting points to millimeters allows translating digital measurements into precise physical lengths required for printing and prepress work.
-
Is the computer point the same as historical points?
-
No, the computer point follows the PostScript standard and differs slightly from historical metal-type points and TeX’s point.
Key Terminology
-
Point (computer)
-
A unit of length in digital typography equal to 1/72 of an international inch, primarily used for font size and layout measurements.
-
Millimeter [mm]
-
The SI unit of length equal to one thousandth of a meter, used in typography for specifying physical print dimensions and layout spacing.
-
PostScript point
-
The standard point measurement in digital typesetting defined as 1/72 of an inch, forming the basis of the computer point.
