Lucida Sans Typewriter将Lucida Sans的人性化外观与打字机字体的固定间距相匹配，其中所有字母的宽度均相同。Lucida Sans垂直的比例、粗壮的主干字重，以及清晰的细节在Lucida Sans Typewriter中得以延续。结果是一个粗大、清晰、固定间距的设计，可在需要功能性、清晰可读的等宽字体的地方使用，打字信函、备忘录和电传，商业表格、发票和装箱单，程序设计和数据处理中，及行式打印机模拟和终端模拟。Lucida Sans Typewriter非常节省空间：10pt的大小相当于12pitch的打字机字体。为了提高80个字符或更多字符的长行的可读性，用户可以添加额外的行间距，相当于字体大小的20％或更多。如果文本需要与Lucida Sans Typewriter配套使用的等宽字体时，则可以使用Lucida Bright。

Lucida Sans Typewriter adapts the humanized look of Lucida Sans to the fixed pitch of typewriter fonts, in which all letters have the same set width. The vertical proportions, strong stem weights, and crisp details of Lucida Sans are continued in the Lucida Sans Typewriter font family. The result is a strong, clear, fixed-pitch design that can be used wherever a functional, legible monospaced font is needed, in typewritten correspondence, memos, and telefaxes, in commercial forms, invoices, and packing lists, in programming and data processing applications, and in line printer emulations and terminal emulations. Lucida Sans Typewriter is economical in setting: at a 10 point size, it is equivalent to a 12 pitch typewriter font. For improved legibility in long lines of 80 characters or more, users can add extra line spacing, equivalent to 20% or more of the font size. When proportional fonts are needed for text to accompany Lucida Sans Typewriter, then Lucida Bright can be used.
