Indices : Terminology : Lining Figures
Lining figures, or ranging figures, are numerals which share a common height. Lining figures are often titling figures, however they may be smaller and lighter than titling figures. Unfortunately, lining figures are the default figure style in most digital fonts where text figures would be more appropriate. However, this problem can be remedied in OpenType fonts which may offer several sets of figures to be used in different types of settings. Sometimes indicated as LF in the font's name.
