Page 33 of the Rice Signs 2017 Traffic Safety Catalog explains how to order custom Street Name Signs. The ordering process is a three-step specification: choose a Style and Style Letter (A through F profiles), specify the Size (6 inch, 9 inch, or 12 inch blank heights based on letter count) and number of letters, and pick a Standard Color (Green, Blue, Brown, Black, or White — plus custom colors on request). The page also covers MUTCD letter-height guidelines that vary with posted speed limit (4 inch letters for streets under 25 MPH, 6 inch letters for 25 to 40 MPH, 8 inch letters above 40 MPH), Available Reflective Finishes (Engineer Grade ASTM Type I for 7-year service life, HIP Type IV for 10 years, Diamond Grade Type IX-XI for 12 years), and the four available fonts: FHWA Type B (default), FHWA Type C, Clearview, and Kelly RD. Customer-supplied artwork is also accepted.
