TYPOGRAPHY, GRAPHICS & SIGN PLACEMENT
2.1. Introduction to Typography. The term typography describes the style, size, and spacing of
letters. Different styles of letters are referred to as fonts or typefaces. Each font is typically available
in a range of sizes. Helvetica medium and Helvetica regular are the principle approved fonts used on
Air Force signs. Helvetica medium is used for primary information on most signs. Helvetica regular
is used for secondary information on identification signs and for certain regulatory signs.
Letterforms used in association with the AF Symbol will be based on the "Arial Black" font (see
2.2. Alternative Typefaces. Use of alternative typefaces may be approved for signs for historic
buildings or bases with unique architectural character such as Randolph Air Force Base. See Chapter
9 - Signs for Historic Buildings. Note: Selected typeface must be in compliance with ADAAG.
2.3. Tile Systems. Proper letter spacing on signs is achieved through use of a tile system. Letter
manufacturers supply letters on proportionately sized paperboard tiles. These tiles have notches
which are used with layout lines drawn on the sign face to align the words and to insure proper
vertical matching. See paragraph 2.10. Sign Assembly Sequence.
2.4. Helvetica Medium. The tile system for Helvetica medium is illustrated on this page. Compare
any tile system purchased for use on Air Force signs with Figure 2.1 to insure conformity in letter
form design and spacing.
2.5. Helvetica Regular. The Helvetica regular tile system is illustrated on this page as a guide for
comparison with alphabets supplied by manufacturers. Arrows are not included in this alphabet,
since all directional signs use Helvetica medium.
