19L 7s is a 2/1-equivalent (octave-equivalent) moment of symmetry scale containing 19 large steps and 7 small steps, repeating every octave. 19L 7s is a great-grandchild scale of 5L 2s, expanding it by 19 tones. Generators that produce this scale range from 692.3¢ to 694.7¢, or from 505.3¢ to 507.7¢.

Temperaments associated with this scale include flattone, whose generator is treated as 3/2, and marfifths, whose generator is treated as 75/56 (marvelous 4th).
