BPM Tap + Grid Calculator
BPM Tap + Grid Calculator
Tap along with a beat to detect BPM, then get instant timing math for bars and note lengths (including triplets).
Use it for chopping samples, placing drums, and planning arrangements without guessing.
BPM Tap + Grid Calculator
Tap to detect BPM, or type it in.
Tip: tap 6-10 times for best results.
Beat (quarter): -- ms
Bar (4 beats): -- sec
1-16 note: -- ms
Bar timing (4-4)
| Length | Time |
|---|---|
| 1 bar | -- |
| 2 bars | -- |
| 4 bars | -- |
| 8 bars | -- |
| 16 bars | -- |
Assumes 4-4 time. Note lengths still help even if you are in a different meter.
Note lengths
| Type | Ms | Seconds |
|---|---|---|
| Quarter | -- | -- |
| Eighth | -- | -- |
| Sixteenth | -- | -- |
| Quarter triplet | -- | -- |
| Eighth triplet | -- | -- |
| Sixteenth triplet | -- | -- |
| Dotted eighth | -- | -- |
| Dotted sixteenth | -- | -- |
Triplets are 2-3 of the straight value. Dotted values are 1.5x.
How to use it
- Tap along with the beat 6-10 times, or type a BPM manually.
- Use the bar timing section to plan intros, hooks, and verses in exact time.
- Use the note lengths section for chops, delays, hat rolls, and tight drum placement.
- Hit Copy results to paste the timing notes into your session notes.
Common uses in beatmaking
- Sample chopping: set slice markers using ms values so chops land cleanly on-grid.
- 808 tuning and slides: tighten note lengths so slides feel intentional, not random.
- Hat control: use 1-16 and triplet ms values to build rolls that stay in pocket.
- Arrangement: convert "8 bars" into a real timestamp so you can work fast.
Note: This tool assumes 4-4. If you are building in 3-4 or 6-8, bar timing will differ, but the note-length math is still useful.
