Commas can theoretically have any size, but in practice most are smaller than a [[12edo]] semitone (100{{cent}}). The following categories, while arbitrary, are used on the Xenharmonic Wiki to classify commas by size.
Commas can theoretically have any size, but in practice most are smaller than a [[12edo]] semitone (100{{cent}}). The following categories, while arbitrary, are used on the Xenharmonic Wiki to classify commas by size.
* [[Unnoticeable comma]]: under 3.5 cents in size. The 3.5-cent limit correlates to the limit of pitch perception (see also [[just-noticeable difference]]).
* [[Unnoticeable comma]]: under 3.5 cents in size. The 3.5-cent boundary roughly correlates to the melodic [[just-noticeable difference]] of pitch perception.
* [[Small comma]]: between 3.5 and 30 cents. Intervals below the 30-cent limit are often considered melodically irrelevant.
* [[Small comma]]: between 3.5 and 30 cents.
* [[Medium comma]]: between 30 and 100 cents. Such intervals are often considered melodically relevant rather than true commas.
* [[Medium comma]]: between 30 and 100 cents.
* [[Large comma]]: over 100 cents in size. The 100-cent limit matches the 12edo semitone.
