At least 3" of countertop frontage should be provided on one side of secondary sinks, and 18" on the other side (including corner sink applications) with the 18" counter frontage at the same counter height as the sink. The countertop frontage may be a continuous surface, or the total of two angled countertop sections. (Measure only countertop frontage, do not count corner space.)
