Introduction

When working with fonts in LuaLaTeX, it's essential to understand the various settings and options available to achieve the desired output. One such option is the WordSpace value, which can be used to create a new font family with specific settings. In this article, we'll explore the different values of WordSpace and how to use them to create a new font family with LuaLaTeX.

What is WordSpace?

WordSpace is a parameter that controls the amount of space between words in a typeset document. It's a crucial aspect of typography, as it can significantly impact the readability and aesthetics of the text. In LuaLaTeX, WordSpace can be set using the fontspec package, which provides a wide range of options for customizing fonts.

Values of WordSpace

The WordSpace value can be set using the \setmainfont command, which is part of the fontspec package. The value can be specified in several ways, including:

Proportional: This is the default value, which means that the space between words will be proportional to the size of the font.
Fixed: This value sets the space between words to a fixed value, regardless of the font size.
Proportional scaled: This value scales the space between words based on the font size, but with a fixed ratio.
Proportional scaled with fallback: This value is similar to the previous one, but with a fallback value in case the scaling is not possible.

Creating a New Font Family with WordSpace

To create a new font family with specific settings, including WordSpace, you can use the following code:

\documentclass{scrartcl}
\usepackage{fontspec}
\setmainfont[
Extension=.otf,
UprightFont=-Regular,
ItalicFont=-Italic,
BoldFont=-Bold,
BoldItalicFont=-BoldItalic,
WordSpace=1.5,
Ligatures=TeX,
Numbers=OldStyle,
OpticalSize=12,
FontFace={bold}{n}{-Bold},
FontFace={bolditalic}{n}{-BoldItalic},
FontFace={italic}{n}{-Italic},
FontFace={regular}{n}{-Regular}
]{MyFont}
\begin{document}
This is a sample text using the new font family.
\end{document}

In this example, we're creating a new font family called MyFont with the following settings:

WordSpace: 1.5, which sets the space between words to 1.5 times the font size.
Ligatures: TeX, which enables TeX ligatures.
Numbers: OldStyle, which uses old-style numbers.
OpticalSize: 12, which sets the optical size of the font to 12 points.
FontFace: We're defining four font faces: bold, bolditalic, italic, and regular.

Customizing WordSpace

In addition to setting the WordSpace value, you can also customize it using other options. For example, you can use the WordSpace key to set the space between words for a specific font face:

\setmainfont[
  Extension=.otf,
  UprightFont=*-Regular,
  ItalicFont=*-Italic,
  BoldFont=*-Bold,
  BoldItalicFont=*-BoldItalic,
  WordSpace=1.5,
  Ligatures=TeX,
  Numbers=OldStyle,
  OpticalSize=12,
  FontFace={bold}{n}{*-Bold},
  FontFace={bolditalic}{n}{*-BoldItalic},
  FontFace={italic}{n}{*-Italic},
  FontFace={regular}{n}{*-Regular},
  WordSpace={bold}{1.2},
  WordSpace={italic}{1.8}
]{MyFont}

In this example, we're setting the WordSpace value to 1.2 for the bold font face and 1.8 for the italic font face.

Conclusion

In conclusion, the WordSpace value is an essential aspect of typography in LuaLaTeX. By understanding the different values of WordSpace and how to use them, you can create a new font family with specific settings and customize the space between words to achieve the desired output. Remember to use the fontspec package to set the WordSpace value and customize other font settings.

Common Issues and Solutions

Error: Unknown key 'WordSpace': Make sure you're using the fontspec package and that the WordSpace key is spelled correctly.
Error: Unknown key 'FontFace': Make sure you're using the fontspec package and that the FontFace key is spelled correctly.
Font not found: Make sure the font file is installed and that the font name is correct.
