Rule B.11: Typographic Symbols

Return to Red Rules

In compliance with Bluebook Rule 6.2(d), TLR spells out the word “percent” when it follows a number that has been spelled out (generally numbers zero through ninety-nine). TLR uses the % sign when referring to a numeral. If the text repeatedly uses percentages throughout the article (for example if the text is data heavy), numerals should be used in all instances.
