Vocal Mic Placement: Distance, Angle and the 15 cm Rule
Recording · 5 min read
Put the singer 15–20 cm from the capsule, mic at eyebrow or nose height angled 10–20 degrees down toward the mouth and turned 15 degrees off-axis so the breath blast crosses the capsule instead of hitting it. Pop filter 8–10 cm from the mic, singer 5–8 cm behind it.
The default that works
15–20 CM
Off-axis 15 degrees · capsule above the mouth
The 60-second answer
15–20 cm for most voices. Move in to 10–12 cm for intimate and breathy, out to 25–30 cm for a loud singer or a good room. Angle the mic 15 degrees off the mouth. Capsule at nose or eyebrow height, tilted down. Tape a mark on the floor.
Distance is a room control, not a volume control
Direct sound follows the inverse square law: double the distance and it drops about 6 dB. Reflected sound off your walls barely changes, because it arrives from everywhere. So moving from 15 cm to 30 cm does not just make the take quieter, it changes the ratio of voice to room by roughly 6 dB. In a bedroom that is the difference between a usable vocal and one that sounds like a bedroom.
Angle and height are free tone controls
Point a mic straight at a mouth and you get the maximum of everything: plosives, sibilance, proximity effect. Turn it 15 degrees and the blast from a P crosses the capsule rather than slamming into it, while a cardioid's response there is still very close to on-axis. Height does something else: aim at the mouth and you get lips and sibilance, aim down from above and you get more chest and less mouth noise.
Setting the mic up, step by step
| # | Do this |
|---|---|
| 01 |
Get the mic away from the walls first At least a metre from the nearest wall and not dead centre. Position in the room matters more than the last 5 cm of distance. 1 m minimum from any wall |
| 02 |
Set the capsule at nose or eyebrow height Tilt it 10–20 degrees down toward the mouth. Keeps the throat open and takes some sibilance out for free. Above the mouth, tilted down |
| 03 |
Set the distance to the voice 15–20 cm default. Loud singer or a good room: 25–30 cm. Quiet and intimate: 10–12 cm with the gain dropped to match. 15–20 cm default |
| 04 |
Turn the mic 15 degrees off the mouth Not 45. At 15 degrees a cardioid barely changes tone but stops taking the full blast of every P and B. 15 degrees off-axis |
| 05 |
Place the pop filter by the mic, not the face 8–10 cm from the capsule, singer 5–8 cm behind it. A filter pressed against the mic does very little. Filter 8–10 cm from the capsule |
| 06 |
Set gain on the loudest line, then tape the floor Peaks at -10 to -6 dBFS on the line they actually belt. A singer drifts 10 cm in an hour, and that is a real tonal change. Peaks -10 to -6 dBFS · floor mark |
The trick: 15 degrees off-axis solves plosives without the pop filter compromise
Everyone reaches for a thicker pop filter, and a thick filter absorbs air blast and high frequencies at the same time. You get fewer pops and a duller, further-away vocal, then add an air shelf to fix the dullness you just paid for. Angling the mic solves it from a different direction. A plosive is a slug of moving air travelling straight out of the mouth in a narrow cone. Rotate the mic about 15 degrees so the capsule is no longer in that cone and the air passes across the diaphragm instead of into it, while the sound — which radiates in all directions and does not care about airflow — arrives essentially unchanged, because a cardioid at 15 degrees off-axis is very close to its on-axis response. You keep the top end and lose most of the pops. Record a line of hard P words straight on, then at 15 degrees, and look at the waveform: the low-frequency thumps are visibly smaller and the rest looks identical.

- Singer facing a bare wall. That reflection arrives straight back into the front of a cardioid.
- Changing distance between takes. Comping across two distances means two tones and two amounts of low end in one performance.
- Pop filter touching the mic. The blast needs distance to disperse. A filter with no gap in front of it is decoration.
- Aiming at the mouth from below. Maximum mouth noise, maximum sibilance, and a closed throat position for the singer.
Distance, angle, height and a mark on the floor. Get those right and the vocal is half mixed before you open a plugin.

FAQ
How far should a mic be from your mouth?
15–20 cm for most singers. Closer for a breathy, intimate sound, further for a loud singer or a good room.
Should the mic be above or below your mouth?
Above, at nose or eyebrow height, angled down. It keeps posture open and reduces sibilance and mouth noise slightly.
Does mic angle really reduce plosives?
Yes. A plosive is a directional blast of air. Turning the capsule 15 degrees out of that path removes most of it while barely changing the response.

5+ years ago I moved to LA with zero connections and started building from nothing — 14-hour days, meeting people and interning at studios. It took me 5+ years to meet and interview 100+ Grammy-winning engineers — then I turned it all into the Vocal Chain Bible.
