Font Size

In order for a sign to be effective, it must be legible from a distance which allows a driver to read it, react to it and carry out any required maneuvers before reaching the sign. TAC’s “Supplemental Guide for Guide and Information Signage in Canada” and AASHTO’s
“Manual of Uniform traffic Control Devices” states that for every 12 m of desired legibility, 25 mm of text is needed. An example is provided in Section A4.2.3.3 showing how letter height is derived based on desired legibility. For guide and information signs, Table 3.3
should be used to determine the letter heights on signs on urban roadways and Table 3.4 should be used on rural roadways. Font sizes are given for several different types of messages. In fringe areas of cities the urban standard is typically used, because of higher
volume and the expectancy.

Borders

A border having the same colour as the text message shall be placed at the perimeter of all guide and information sign panels to increase the sign’s conspicuity and provide an overall finished appearance. The border shall be extended to the edge of the sign panel with no
background colour shown between the border and the edge. The border thickness and radius of curvature for the corners is shown in Table.

Abbreviations

Abbreviations may be used to reduce message length if needed or to balance the message over the face of the sign. The unabbreviated version shall be used if there is sufficient space. Abbreviations should be used with care, ensuring that only commonly used and
understood abbreviations are utilized for signs. Periods are used after abbreviations for any type of roadway (i.e. Freeway, Road,Highway, Boulevard and Junction). Periods are not used when abbreviating lengths or directions and after the abbreviations for Range and Township Roads. In Alberta, the following abbreviations (with and without periods) are recognized.
