What is the highest amplitude massage gun? Is high amplitude always better? This post will seek to answer these questions.

We have been buying and reviewing massage guns for a while now, and though we don’t consider ourselves massage gun experts, we know a thing or two about the amplitude of a massage gun.

We also know that amplitude is not the only thing that should be paid attention to. There are other features to look out for. We’ll list devices that we’re sure deliver what they promise.

Follow along!


If you are pressed on time and would rather quickly find a high amplitude massage gun, check out our best recommendations in both full-sized and mini massage guns categories:

  • Achedaway Pro (full-sized massage gun) – does not only have the longest amplitude in the market, it also ranks best in other features – i.e. plenty of stall force, and great percussion range.
  • Ekrin Bantam (mini) – has 10mm amplitude which is less than the longest for a miniature gun (12mm), but have more stall force, are better equipped, and more affordable.

What is Amplitude/Stroke Length in Massage Guns

theragun elite Highest Amplitude stall force measurement

A quick definition for amplitude is the distance covered by the massage gun head as it moves back and forth.

That movement results in percussions (hits per minute) that are delivered on the skin.

The longer the distance covered the harder the punch you get, which leads to a better percussive massage.

Why Is It Important?

Well, the amplitude is what pretty much makes it a percussive massage. Before percussion massagers came into the market (before Theragun had become famous for it), vibrational therapy was the favored recovery method.

Massage guns changed the trend to percussive therapy following Theragun’s invention. Even though many massage guns came into the market, they didn’t pay attention to the amplitude, and as a result, those devices back then only delivered vibrational therapy (surface-level massage).

Today however, after Theragun had made everyone realize why the amplitude is important – the longer the better – many brands have chosen to make amplitude count in their devices.

A long amplitude combined with the right intensity (most devices rev up to about 3000 hits per minute) is what characterizes a good enough percussive massage. There is a third element that we’ll also discuss in a minute.  

How Can You Know If a Massage Gun Has a High Enough Amplitude?

Well, we had a bit of a debate about how to classify amplitude in massage guns. We couldn’t find many such classifications anywhere. We decided to come up with our own based on what we know about massage guns.

Full-Sized Guns

Low9-11 mm
Moderate12-13 mm
High14-16 mm
Full Sized Massage Gun Amplitude Classification

Mini Massage Guns

Low6-8 mm
Moderate9-10 mm
High12+ mm
Mini Massage Gun Amplitude Classification

Does 1 mm, Tiny, Make any Difference?

We’d say, not really. That is a very small margin to have any significant difference.

We’ll also say that even though the difference between a device with a 12mm amplitude and one with 16mm amplitude can certainly be felt, you’ll rarely feel the difference between a device with 15mm amplitude and the one with 14mm amplitude.

What is the Maximum Amplitude a Device can Have?

Well, as far as we know, 16mm is the highest amplitude on the market today.

We have picked devices that have this highest amplitude and included them first in our list. Note that this can only be found with the full-sized massage guns.

For mini massage guns, 12mm is the longest amplitude. As far as we know, only Theragun Mini has this amplitude. However, it’s not necessarily the best mini massage gun on the market today because the stall force isn’t as high as some of the others.

Full-Sized Massage Gun Stroke Length Comparison

Here is the list of guns with the highest amplitude. As you can easily see, the most desirable 16 mm amplitude is available from Achedaway and obviously Theraguns, but the rest of competition is right behind them.

Mini Massage Gun Stroke Length Comparison

At first glance it seams like the king is only one: Theragun mini. Other guns can reach a maximum of 10mm amplitude, yet as we have already mentioned, balanced combination of all parameters is important and so Ekrin is our top recommendation.

How Does Stall Force Relate to Amplitude?

Another important aspect that we cannot ignore, even though this post is dedicated to amplitude, is the stall force. This is the amount of pressure it takes to stall the motor of a device, consequently shutting off the device. 

You cannot talk about amplitude and forget to talk about stall force (that is if you want a powerful percussion massager). That means that the highest amplitude percussion massager is not necessarily the best and most powerful massage gun.

Sometimes muscle soreness can occur deep into the muscle tissue. Simply passing the massage gun over that particular area may not be effective enough to relieve the soreness.

That means you have to apply some pressure using the massage gun. You’ll agree with us that it will be quite frustrating if your massage gun keeps stalling as you try to apply some pressure.

Many cheap massage guns (there are hundreds on Amazon) use amplitude as their main selling point, promising the best in amplitude but delivering poorly in stall force. Many have devices with less than 25-30lbs. of stall force. This is not enough stall force to deliver a deep tissue massage especially on large muscles – quads, hamstrings, and glutes.

It’s About Amplitude AND Stall Force

We’ll give you a little expert advice (expert; we said it!). Always look for both amplitude and stall force information. You’ll do yourself a huge favor by skipping guns that promise you a long amplitude but have a very weak stall force. You’d better go for a device that promises slightly less amplitude but more stall force.

For instance, a device with 12-13mm amplitude but has more stall force is a sweet spot. This is because even though it may feel way below the high 16mm mark, with enough stall force, you can press such a device against the skin and actually get a much deeper massage.

Devices like Ekrin B37 and B37S have received high praise from buyers because of this. The same goes for mini devices like Ekrin Bantam or Addsfit Mini Pro. These have slightly lower amplitudes but have more than enough stall force.

Is High Amplitude Always Better? 

No. Not always. There are certain situations that call for moderation. High amplitude means harder punches and a device with 16mm amplitude will punch harder than a device with 10 or 12mm amplitude.

Bantam has a nice balance between amplitude and stall force.

However, while some people may prefer a deeper massage, some areas of the body don’t need the heavy-hitting punches. Even as a bodybuilder, you’ll probably only need harder punches around your glutes and hamstrings or other areas with large muscles.

But for other areas, like the neck area, you’ll probably just need a 12mm amplitude device. Also, some massage routines call for a delicate massage. If you just want to relax or get some sleep or even warm up the muscles, you’ll not need a 16mm amplitude gun.

In fact, a device with a moderate to low amplitude may be more effective for such routines. This is because such devices tend to rev faster and the faster percussion helps accelerate the blood flow.

Older adults and those with more sensitive skin should also consider massage guns with a lower amplitude to reduce the risk of skin abrasion or tearing. Another option for managing sensitive skin is to use a soft head attachment for your massage gun (most devices come with such).

It’s therefore important that you figure out what kind of routine you need a massage gun for. It’s also wise to check out a device based on both stall force and amplitude.

Highest Amplitude Massage Gun (Full-Sized) – Our Best Picks

The following products have the industry-leading 16mm stroke length.

Achedaway Pro – Our #1 Pick

Achedaway Pro features

Achedaway Pro has the industry highest 16mm amplitude with some other great features as well. It’s a very powerful percussion massager with over 60lbs. of stall force – it will definitely punch harder and can be pressed hard against the skin.

The build materials are great and it comes with an angled handle for better ergonomics. It’s rather bulky but that doesn’t stop it from delivering awesome performance and it does so very quietly (it’s the quietest massage gun in this category).

achedaway pro Measured Amplitude
Achedaway PRO – 16mm amplitude is confirmed.

It’s well equipped too; we loved those aluminum attachments and carrying case. It comes as a standard package with removable battery or an extended set including additional spare battery.

Overall, we love the device and can wholeheartedly recommend it. It is also the best value when it comes to the highest amplitude massage gun for the money.

Achedaway Pro is awesomely priced, costing $299 regular but you can get $50 discount when the coupon MGA50 is used in the Achedaway Store right here. The final price will be $249.

Theraguns: Prime, Elite and Pro

high amplitude theragun massagers

Theragun being the pioneers of the long amplitude have to feature here. Their 3 full-sized massage guns all have the same 16mm amplitude.

What separates them from each other is mainly the stall force. Prime has the weakest stall force while Pro is the strongest. Elite falls in between but it’s closer to Prime than Pro.

Theragun Pro Measured Amplitude

They also have the best ergonomics in the business – their multiple grip handles are not rivaled by anyone so far.

Despite all their awesomeness, their biggest drawback is their high prices. For example, their entry-level Prime costs more than Achedaway Pro – which is actually way more powerful.

TIP To find out more you can read our Theragun comparison post or the individual reviews: the Prime, the Elite and the Pro.

More High Amplitude Percussion Massagers we Recommend

These do not have a 16mm amplitude but have something close – the difference is minimal and can barely be felt.

Hypervolt Plus

hypervolt plus specifications

This one has somewhere between 14 mm amplitude. Hyperice does not disclose this information and we had to do our own measuring.

The Hypervolt Plus has a high stall force and 25% more intensity compared to Theraguns. That means that you will likely not feel the small 1-2mm difference in stall force.

hypervolt plus Measured Amplitude
Hypervolt Plus has 14mm amplitude.

In our individual review for Hypervolt Plus, we praised it for having more power than Theragun Elite. It also has a removable battery like Theragun Pro and Achedaway Pro.

It’s a proven high-quality device but it’s very expensive. It’s not as well equipped as some of our best picks here and it’s not the best ergonomically. It lacks a carrying case and is the heaviest in our list – 3lbs.

TIP You can check the current price on Amazon →

Opove M3 Pro MAX

OPOVE M3 Pro Max specifications

Opove M3 Pro Max is the cheaper alternative to Hypervolt Plus, or the new Hypervolt 2 Pro. It looks very similar to Hypervolt Plus – similar configuration.

It has a 15mm amplitude and up to 50lbs. of stall force. It has the same percussion range as the Hypervolt Plus but feels slightly more powerful.

It’s a very simplified device – it doesn’t have a pressure sensor like Hypervolt Plus. But it has a better battery performance and is lighter (2.3lbs) than Hypervolt Plus.

Opove sells it at $169 in their store, and we think the price is great for what kind of specs you get. For more information, refer to our full Opove M3 Pro Max review.

Urikar AT1

urikar at1 specifications

Another one with 16mm amplitude – on par with Theraguns and our beloved Achedaway Pro.

Urikar AT1 has an innovative design that screams tech everywhere. For instance, it has a massage head recognition feature, a smart mode that adjusts speeds automatically and an infrared sensor that detects proximity to the body.

We also like the fact that it’s very quiet for a high amplitude massage gun – Urikar did a very good job insulating the motor.

It is advertised as revving at a very high frequency – up to 3600rpm despite the long amplitude, but unfortunately it is not. It is only revving up to a little over 2000 rpm. We checked with a digital tachometer.

It is definitely the largest of them all, which you can see by looking at a picture below that shows it next to Achedaway Pro. It also lags behind in stall force – stalls relatively easy so definitely not the most powerful massage gun out there.

At least it is an affordable one (for a high amplitude gun, that is).

It usually costs $269 but you can use the code AT1 to get a massive 40% off that price – it then only costs $161. Get the Urikar AT1 gun here.

Hypervolt 2 Pro

hypervolt 2 pro features

Here’s another Hypervolt, the just-released successor of the Plus model. As the Plus, the new Hypervolt 2 Pro also has the same 14mm amplitude, which really feels okay and high enough.

It does, however, have less stall force, and the percussion range is also lower than in the good old Hypervolt Plus. As we explained in our Hypervolt 2 Pro vs Hypervolt Plus comparison, the new one does 2700 maximum percussions per minute, while the Plus revs up to 3200 percussions per minute.

What all of the above means is that, as far as the performance is concerned, the new 2 Pro isn’t an upgrade versus the Plus – it might be quite the opposite. That said, it is still a powerful device, and definitely a high amplitude massage gun.

hypervolt 2 pro Measured Amplitude
Hypervolt 2 Pro has 14mm amplitude – as measured and confirmed.

But there are some new, exciting features coming with the Hypervolt 2 Pro. It has a new pill-shaped handle, is lighter and holds better than its predecessor. The handle grew by about an inch, to help reach the back more easily – mid back especially.

Another noteworthy thing is the re-designed control panel, now with the slick-looking dial that you use to activate the gun and navigate between its 5 speeds. The dial means no more buttons on the main control panel, and it is a very cool feature.

We also like the fact it feels more hushed as compared to the Plus model.

Highest Amplitude Mini Massage Guns – Best Picks

These are the new trendy small massage guns with high amplitude.

Theragun Mini

theragun mini features

As the kings of amplitude, Theragun equipped their mini gun with a high amplitude. It has a 12mm amplitude and is the highest in the mini category.

Theragun mini Measured Amplitude
Theragun mini is the highest amplitude mini massage gun – 12mm stroke length.

It can punch hard but has probably less than 20lbs. of stall force. This is not enough to massage large muscles. It’s also very expensive ($199) but very poorly equipped – just the one attachment and has no USB-C charger.

It’s a great addition if you already have any of the large sized Theraguns because the attachments are interchangeable.

We’d suggest going for awesome alternatives out there. They may not have better amplitude, but they have more stall force and have more percussions.

Addsfit Mini Pro

addsfit mini pro mini massage gun

This is a perfect alternative to Theragun mini. It has 10mm amplitude but still very good for a mini massage gun.

addsfit mini pro massage gun in use
Extensible handle – Addsfit Mini Pro

What makes it unique is the unique twist on ergonomics – it is pretty awesome, thanks to the extensible handle that extends from 6.5″ to over 9.5″ with a simple twist. So one twist, and the gun gets taller, and thus easier to use on the mid and lower back.

It also punches more intensively with a percussion range of 1100-3300rpm. Theragun has a less intense range – 1750-2400.

It has a better stall force – over 28lbs., more than the Mini, but less than the mini-sized Bantam (below).

Addsfit has 5 speed gears and an excellent capacity battery. It can easily do 5-6 hours on a single charge. It conveniently charges via USB-C cable.

The Mini Pro comes with a carrying case and 5 attachments. Warranty is 3 years if you register the device on addsfit.com

It normally costs $159, but we have the MASSAGE25 code that you can apply and get it 25% cheaper, for only $119.25. Check it out on addsfit.com

Ekrin Bantam

ekrin bantam features

Here is another excellent device from Ekrin. It’s the mini version of the two full-sized guns – Ekrin B37 and B37S.

It also has a 10mm amplitude but it’s stronger than both Theragun Mini and Addsfit Mini Pro. It has 35lbs. of stall force which makes it more powerful than some of the full-sized massage guns e.g. Theragun Prime. This is the strongest mini gun you can get, and yet, it is the lightest one, at only 1.3 lbs.

It’s a nicely made mini massage gun, elegant with premium feel to it. Materials used are great, and so is the equipment; 4 attachments, a carrying case, and a USB-C charger.

The battery is Samsung-branded one, and it does about 5 hours on on a single charge, which is not bad for a mini gun. We’ve been using our Bantam on daily basis for almost a year now, and it shows no signs of wear and tear (including the battery).

It comes with a lifetime warranty – a rarity these days. Buy with confidence.

It’s greatly priced at $149.99. But you can get it for 20% less if you use the MGA20 coupon code. It then costs $119.99.

Highest Amplitude Massage Gun – Conclusion

So hopefully now you can easily pick the highest amplitude massage gun with the information above.

Amplitude determines how much of a punch you can get from a massage gun. The better the amplitude the better the percussive massage you can get.

However, it’s not always the best thing to have the longest amplitude. Find out what you want to do with the massage gun before deciding whether to go for one with a high amplitude or choose one with a moderate amplitude.

Another important factor to consider is the stall force. Find out if a device has enough stall force.
