Short answer: 140 BPM, half-time feel. That is the safe modern default and where most current trap lives. The longer answer depends on which trap you are making, who is rapping over it, and what platform the track is going to.
This guide walks through the why behind 140 BPM, the subgenre exceptions, the way half-time actually works, and how to pick a tempo that fits the vocalist instead of fighting them.
Why trap producers count it twice
A typical trap beat is written at 140 BPM but felt at 70. The kick lands on the 1, the snare lands on the 3 (not the 2 and 4 you would hear in rock or pop), and the hi-hats subdivide the 16ths. That gives you the slow head-nod groove of half-time with the hi-hat detail of double-time. It is the defining rhythmic move of the genre.
If you write the same idea at 70 BPM instead, your DAW grid gets in your way — every rapid hi-hat roll becomes a 64th-note nightmare to edit. So producers write at 140 (where 16th-note hats are easy to draw) and let the snare placement do the half-time work.
Once you understand this, a lot of the confusion around trap tempo disappears. The genre is built on a deliberate ambiguity: drums sound slow, top layers sound fast, and the listener's brain locks onto the kick-snare pocket as the "real" tempo.
Subgenre tempo cheat sheet
Trap is not one tempo. Each branch has a center of gravity:
| Subgenre | Typical BPM | Notes | | --- | --- | --- | | Atlanta trap (Future, Migos era) | 130–145 | Standard half-time pocket | | Drill (Chicago / UK / NY) | 140–150 | Snare on the 4, sliding 808s | | Phonk | 130–140 | Cowbells, distorted 808s, Memphis influence | | Plugg / pluggnb | 130–140 | Light swing, melodic, R&B-adjacent | | Hyperpop-trap crossover | 150–170 | Often double-time vocal delivery | | Sad / emo trap | 75–90 | Straight, no half-time trick | | Trap-house / EDM crossover | 100–115 | Designed for festival drops |
A track at 142 BPM is more or less always going to sound like modern trap. A track at 105 is going to sound like something else, even if the drum kit is identical. Tempo is the first identity choice.
Match the tempo to the vocalist
The single biggest mistake newer producers make is picking a tempo before the vocalist hears it. Some rappers ride a 140 pocket effortlessly. Others sound rushed at anything above 130. A few prefer 148–152 because the snare-on-the-4 drill pocket gives their flow more room.
If you are producing for a specific artist, send them a 30-second loop at three tempos — say 135, 140, and 146 — and ask them to mumble over each before you commit. The pocket they fall into naturally is the pocket they will write to. Trying to convince a writer to perform at a tempo their body resists is a losing battle.
If you are producing for yourself or for placement, 140 BPM is the safest tempo to demo at. It pitches up and down well in the DAW (you can deliver alternate tempos without re-recording), fits most modern templates, and reads as "correct" to A&Rs scanning beat packs.
Counting the snare placement
In trap, the snare placement defines the subgenre as much as the tempo does.
- Snare on the 3 — Atlanta trap, classic half-time
- Snare on the 4 — drill, modern UK rap
- Snare on the 2 and 4 — straight pocket, often hyperpop or trap-influenced pop
- Snare on the offbeat (e+, a+) — rolling or skippy, often heard in plugg
If you change nothing but the snare placement, the same kick pattern can move between Atlanta trap and Chicago drill in one move. This is why understanding placement matters more than memorizing exact tempos.
Tempo and platform
Where the track is going changes the right tempo.
- TikTok / Reels — short-form often prefers slightly faster tempo (142–148) because the hook needs to land in 8 bars and the energy needs to read in 4 seconds.
- Spotify singles — 138–142 is the sweet spot. Long enough pocket for a 2:30 song to breathe.
- Sync (film, ads) — depends entirely on edit timing. Often a music supervisor wants the same idea at multiple tempos. Render alts.
- DJ sets — round tempos (140, 145) mix more cleanly than 137 or 143.
Where ONYX defaults land
When you pick TRAP in ONYX, the engine defaults to 140 BPM with a half-time pocket, snare on the 3, triplet hi-hats. When you pick DRILL, it shifts to 144 BPM with the snare moved to the 4 and slid 808s. You can override either per render.
If you have a vocalist's reference vocal already, drop it on the Reference Deck and ONYX detects the BPM and key automatically, then renders a bed underneath. This is the fastest way we know to demo a beat to an artist without guessing tempo.

Common mistakes to avoid
- 01Writing at 70 BPM "to feel the half-time." Just write at 140. Your future self will thank you when you need to draw a 16th-note hat roll.
- 02Using 808s tuned to a key the rapper does not sing in. Always check the 808 root against the vocalist's comfortable range.
- 03Slowing a 145 beat to 138 in the DAW. Re-render from your source. Time-stretching trap hats sounds like garbage in 2026.
- 04Mixing trap and drill snare placements in the same drop. Pick a pocket and commit. Hybrid grooves usually feel indecisive.
- 05Skipping the half-time pre-listen. Always solo the kick and snare and verify the pocket before adding hats.
TL;DR
- Default to 140 BPM, half-time, snare on the 3.
- Move to 144 BPM with snare on the 4 for drill.
- Drop to 80–90 BPM straight for sad/emo trap.
- Always test the tempo against the vocalist before locking it.
- Render alts. The cheapest insurance against an A&R revision.
