Adobe Font Metrics File – file format by Adobe Systems
AFM (Adobe Font Metrics File) is a file format developed by Adobe Systems to store font metrics data for Type 1 fonts. It contains information about the font’s character widths, heights, and other attributes, which is used by applications to render text correctly.
Introduction to Adobe Font Metrics Files (AFM)
AFM files are specialized text files that provide comprehensive information about a particular typeface. Developed by Adobe, AFM files are an integral part of the PostScript language for accurately describing the metrics and attributes of a font. These files contain essential data that enables applications to correctly display and manipulate text in digital documents and graphical environments.
AFM files provide precise measurements and spacing for each glyph in the typeface, including character width, character height, and baseline position. Additionally, they specify kerning information, outlining how character pairs should be adjusted to prevent overlapping or excessive spacing. AFM files also contain font license information, copyright notices, and a variety of other properties that are relevant to the font’s usage and distribution.
Opening AFM Files
AFM (Adobe Font Metrics File) files contain font metric information used by Adobe’s Type Manager font rendering system. They provide data about the character widths, heights, and other metrics necessary for accurate font display and typesetting. To open an AFM file, you can use various software applications or online tools.

Adobe Font Metrics File (AFM)
The Adobe Font Metrics File (AFM) is a text file format developed by Adobe Systems to store information about the metrics and characteristics of a typeface. It provides detailed data essential for accurate text rendering, including character widths, heights, and kerning pairs. The AFM file complements the corresponding font file, providing additional information that enhances typographic control and consistency.
AFM files are crucial for various applications, including desktop publishing, typesetting, and font development. They enable applications to accurately position and scale text, ensuring proper spacing and alignment. By referencing the AFM file, software can calculate the optimal spacing between characters and lines, resulting in aesthetically pleasing and legible typography. Additionally, AFM files contain metadata such as the font name, copyright information, and licensing terms, providing valuable information for users.
