What Is This Tool?
This converter transforms the typography unit called 'en' into millimeters, enabling precise translation of font-relative spacing into physical dimensions used in print and graphic design layouts.
How to Use This Tool?
-
Enter the value in 'en' units that you want to convert.
-
Select 'en' as the source unit and 'millimeter [mm]' as the target unit.
-
Click the convert button to see the equivalent size in millimeters.
-
Use the result to specify precise dimensions for print layouts or prepress work.
Key Features
-
Converts the 'en' unit, a typography measurement relative to font size, into millimeters.
-
Provides exact numerical translation for use in print and layout design.
-
Supports graphic design, print production, desktop publishing, and web layout contexts.
-
Displays conversion based on the formula: 1 En = 0.1757299018 mm.
Examples
-
Converting 5 En results in approximately 0.8786 millimeters.
-
Converting 10 En results in approximately 1.7573 millimeters.
Common Use Cases
-
Specifying the length of an en dash used in typography to indicate ranges and connections.
-
Defining widths of en spaces or indentations relative to font size in CSS and layout rules.
-
Setting physical dimensions such as paper sizes, margins, and column widths in print design.
-
Translating font-relative units into actual measurements for prepress and production.
Tips & Best Practices
-
Ensure you know the current font size since the 'en' unit depends on it for accurate conversion.
-
Use this tool to convert relative units into absolute millimeter values for precision in print layouts.
-
Double-check layout requirements by comparing both typography units and physical measurements.
Limitations
-
The 'en' is a relative unit dependent on font point size; its absolute length varies by font metrics.
-
Conversion to millimeters requires knowing the exact font size used in the design.
-
Values may not be universally consistent across different typefaces and layouts.
Frequently Asked Questions
-
What is an 'en' in typography?
-
An 'en' is a horizontal unit that equals half an 'em', which corresponds to half the current font size, used for relative lengths in layouts.
-
Why convert 'en' to millimeters?
-
Converting 'en' to millimeters helps translate font-relative spacing into precise physical dimensions for print and layout design.
-
Does the value of an 'en' unit stay the same?
-
No, the absolute value of an 'en' varies depending on font size and typeface, making context important for conversion.
Key Terminology
-
En
-
A typography unit equal to half an em, typically half the font point size, used for relative widths in layout and spacing.
-
Millimeter [mm]
-
The SI unit of length equal to one thousandth of a metre, used for precise physical dimensions in print and layout work.
-
Em
-
A relative typography unit representing the current font size, serving as the basis for units like the en.
