The 19-odd-limit is the set of all rational intervals for which neither the numerator nor the denominator of the frequency ratio exceeds 19, once all powers of 2 are removed. To the 17-odd-limit, it adds 9 interval pairs involving 19.

Below is a list of all octave-reduced intervals in the 19-odd-limit.

The smallest equal division of the octave which is consistent in the 19-odd-limit is 80edo; that which is distinctly consistent in the same is 217edo.
