Swing Timing Calculator

See the long and short parts of an eighth-note pair.

Tempo (quarter-note BPM)

First note share (%)

Your result

First eighth (ms): 300
Second eighth (ms): 200
Offbeat delay (ms): 50

How this works

pair = 60000/BPM; first = pair × swing/100

Use the result carefully

Here 50% is straight and 66.667% is a triplet-like pair. Manufacturer swing scales can differ.
