What this tool is for
The tool counts syllables in each lyric line and multiplies by your chosen pace. Section tags like [Chorus] split the estimate so you can balance the arrangement. Treat the number as a planning aid — not an exact runtime.
Long-section warning
Sections estimated past ~45 seconds are highlighted. Suno tends to rush or clip very long blocks — see song length limits.
FAQ
How accurate is the estimate?
It is a rough guide from syllable count and pace. Melody, repeats and instrumental gaps shift the real runtime.
Does it upload my lyrics?
No — the estimate is computed locally in your browser.
Why does it warn about long sections?
Very long single sections can get truncated or rushed; the tool flags ones past about 45 seconds.
