Ardhasamavṛttas are meters in which each half (ardha) has the same syllabic pattern, defined by a particular configuration of light and heavy syllables. They contrast with samavṛttas, wherein each quarter (pāda) has the same syllabic pattern. In ardhasamavṛttas, the pattern of the first and third quarters (i.e., the odd quarters) is identical, and the pattern of the second and fourth (i.e., the even) is identical, but the odd quarters are not identical to the even quarters.

The most common ardhasamavṛtta in use is the puṣpitāgra.
