s, a broader definition for the term “font” evolved, because different sizes of a single style—separate fonts in metal type—are now generated from a single computer font, because vector shapes can be scaled freely. “Bulmer”, the typeface, may include the fonts “Bulmer roman”, “Bulmer italic”, “Bulmer bold” and “Bulmer extended”, but there is no separate font for "9-point Bulmer italic" as opposed to "10-point Bulmer italic".

There are thousands of typefaces.

Unlike a digital typeface it would not include a single definition of each character, but commonly used characters (such as vowels and periods) would have more physical type-pieces included. A font when bought new would often be sold as (for example in a Roman alphabet) 12pt 14A 34a, meaning that it would be a size 12-point font containing 14 uppercase 'A's, and 34 lowercase 'A's.

 (rather than the harder alloy used for other pieces). The reason for this spacing strip being made from "lead" was because lead was a softer metal than the traditional forged metal type pieces (which was part lead, antimony and tin) and would compress more easily when "locked-up" in the printing "chase" (i.e. a carrier for holding all the type together).

In the 1880s–90s, "hot lead" typesetting was invented, in which type was cast as it was set, either piece by piece (as in the Monotype technology) or in entire lines of type at one time (as in the Linotype

The regular or standard font is sometimes labeled roman, both to distinguish it from bold or thin and from italic or oblique. The keyword for the default, regular case is often omitted for variants and never repeated, otherwise it would be Bulmer regular italic, Bulmer bold regular and even Bulmer regular regular. Roman can also refer to the language coverage of a font, acting as a shorthand for "Western European."

Weight

The weight of a particular font is the thickness of the character outlines relative to their height.
A typeface may come in fonts of many weights, from ultra-light to extra-bold or black; four to six weights are not unusual, and a few typefaces have as many as a dozen. Many typefaces for office, Web and non-professional use come with just a normal and a bold weight. If no bold weight is provided, many renderers (browsers, word processors, graphic and DTP programs) support faking a bolder font by rendering the outline a second time at an offset, or just smearing it slightly at a diagonal angle.

The base weight differs among typefaces; that means one normal font may appear bolder than some other normal font. For example, fonts intended to be used in posters are often quite bold by default while fonts for long runs of text are rather light. Therefore weight designations in font names may differ in regard to the actual absolute stroke weight or density of glyphs in the font.

Attempts to systematize a range of weights led to a numerical classification first used by Adrian Frutiger
Adrian Frutiger
Adrian Frutiger is one of the prominent typeface designers of the 20th century, who continues to influence the direction of digital typography in the 21st century; he is best known for creating the typefaces Univers and Frutiger.-Early life:Adrian Frutiger was born in Unterseen, Canton of Bern, as...

 typeface: 35 Extra Light, 45 Light, 55 Medium or Regular, 65 Bold, 75 Extra Bold, 85 Extra Bold, 95 Ultra Bold or Black.
Deviants of these were the "6 series" (italics), e.g. 46 Light Italics etc., the "7 series" (condensed versions), e.g. 57 Medium Condensed etc., and the "8 series" (condensed italics), e.g. 68 Bold Condensed Italics.
From this brief numerical system it is easier to determine exactly what a font's characteristics are, for instance "Helvetica 67" (HE67) translates to "Helvetica Bold Condensed".

There are many names used to describe the weight of a font in its name, differing among type foundries and designers, but their relative order is usually fixed, something like this:
  • Hairline
  • Thin
  • Ultra-light
  • Extra-light
  • Light
  • Book
  • Normal / regular / roman / plain
  • Medium
  • Demi-bold / semi-bold
  • Bold
  • Extra-bold / extra
  • Heavy
  • Black
  • Extra-black
  • Ultra-black / ultra

The terms normal, regular and plain, sometimes also book, are being used for the standard weight font of a typeface. Where both appear and differ, book is often lighter than regular, but in some typefaces it is bolder.

Although rarely encountered, a typographic face may be accompanied by a matching calligraphic face (cursive, script), which might be considered a further font style of one typeface.

Oblique type is a form of type that slants slightly to the right, used in the same manner as italic type. Unlike italic type, however, it does not use different glyph shapes; it uses the same glyphs as roman type, except distorted...

fonts are not true italics, because they lack the change in letter shapes which is part of the definition of an italic.

On the other hand, there are typefaces with upright characters that take a more cursive form without a change in angle. For example the Cyrillic minuscule ‘т’ may look like a smaller form of its majuscule ‘Т’ or more like a roman small ‘m’ as in its standard italic appearance; in this case the distinction between styles is also a matter of local preference.

In Frutiger’s nomenclature the second digit for upright fonts is a 5, for italic fonts a 6 and for condensed italic fonts a 8.
