Amplitude (how far the head travels) and stall force (how hard you can press before it stops) decide how deep a massage gun feels. Full-size guns with 12 to 16 mm amplitude suit large muscle groups and athletes; mini guns with shorter amplitude suit travel and lighter use. Then check speed range, attachments, noise, weight and battery life.
Massage guns look alike, but three numbers decide how they feel: amplitude, stall force and speed.
The specs that matter
| Spec | What it means | Typical range |
|---|---|---|
| Amplitude | How far the head travels | 7 to 16 mm |
| Stall force | Pressure before the motor stops | Varies by brand method |
| Speed | Percussions per minute | About 1,750 to 3,200 |
| Weight | Hand and arm fatigue | Under 0.5 kg mini to over 1 kg |
| Noise | Comfort and use at home | Brands quote dB figures |
Full-size or mini?
- Full-size guns have more amplitude and stall force for quads, glutes and back.
- Mini guns fit in a gym bag and suit calves, forearms and travel.
Other checks
- Handle shape: angled or multi-grip handles help you reach your own back.
- Battery life and charging method (USB-C is convenient).
- App or presets if you want guided routines.
- Warranty length and support.
Using it well
Keep sessions short, about one to two minutes per muscle group, move the head slowly, and do not press through pain.

Common questions
What is a good amplitude for a massage gun?
Many full-size guns sit around 12 to 16 mm, which reaches deeper into large muscles. Mini guns often run 7 to 10 mm for lighter, portable use.
What does stall force mean?
The pressure at which the motor stalls. Higher stall force means you can press harder without the gun stopping. Brands measure it differently, so compare within the same brand where possible.
Which attachment should I use?
A round or flat head for general use, a bullet head for small areas, a fork for either side of the spine and a soft head for sensitive spots.
Where should I avoid using a massage gun?
Avoid bones, joints, the neck's front and sides, injuries and areas with poor circulation. Ask a doctor or physio if you have a medical condition.
