Sanskrit Poetic Meters (Chandas)

Chandas (छन्दस्) is the traditional science of Sanskrit prosody — one of the six Vedangas, the auxiliary disciplines developed to support correct study and recitation of the Vedas. Its foundational surviving text is Pingala's Chandahshastra, composed around the 2nd century BCE, which first systematised the notation still used to describe Sanskrit meters today. Modern comprehensive compilations catalogue over 600 named meters — a far larger repertoire than in most other metrical traditions — though only a few dozen recur regularly across well-known classical and devotional literature, and this page focuses on those.

Two ways a meter can be measured

Sanskrit meters split into two fundamentally different systems, and knowing which one you're looking at changes what "correct" even means:

• Varṇavṛtta (वर्णवृत्त) — syllabo-quantitative meters, fixed by both an exact syllable count and an exact laghu-guru pattern. Nearly all classical Kavya (literary) meters — Vasantatilaka, Mandakranta, Shardulavikridita — work this way.
• Mātrāvṛtta (मात्रावृत्त), also called Jāti (जाति) — quantitative meters, fixed only by a total mātrā (mora) count per line; the actual number of syllables can vary, since two laghus and one guru both equal the same total weight. Many older Vedic meters lean toward this looser counting.

Within Varnavritta specifically, meters are further classed by how much their four lines (pādas) resemble each other:

• Samavṛtta (समवृत्त, "even") — all four pādas follow the identical pattern. Most well-known classical meters, including Vasantatilaka and Shardulavikridita, are Samavritta.
• Ardhasamavṛtta (अर्धसमवृत्त, "half-even") — the 1st and 3rd pādas share one pattern, the 2nd and 4th share a different one.
• Viṣamavṛtta (विषमवृत्त, "uneven") — all four pādas can differ from one another.

How to recognize the Anushtubh (Shloka) meter

Since Anushtubh accounts for the vast majority of classical narrative verse, it's worth knowing its scanning rule specifically — it's looser than most other meters, which is part of why it became the default for long narrative works. Each pāda has 8 syllables, and within each pāda:

• The 5th syllable must be laghu.
• The 6th syllable must be guru.
• The 7th syllable must be guru in the 1st and 3rd pādas, and laghu in the 2nd and 4th.

The remaining syllables (1st–4th and 8th) are comparatively free. A famous example, from the Bhagavad Gita:

Checking just the first pāda ("yadā yadā hi dharmasya," 8 syllables) against the rule: the 5th syllable (ma in dharmasya) is laghu, the 6th (sya) is guru — matching the pattern exactly. This partial-fixed, partial-free structure is precisely why Anushtubh could sustain the length of works like the Mahabharata without becoming monotonous.

A real example: five meters in one work

The Śikṣāṣṭaka ("Eight Verses on Instruction"), a short devotional Sanskrit hymn, is a genuine, verifiable illustration of how deliberately meter is chosen in classical composition — each of its 8 verses is typically composed in a single metre, but the work as a whole moves through five different ones: Śārdūlavikrīḍita, Vasantatilakā, Anuṣṭubh, Viyoginī and Upajāti. The changing meter across the verses is itself part of the composition's structure, not incidental — a reminder that meter in Sanskrit poetry functions closer to how key or tempo functions in music than how rhyme scheme functions in English poetry.
