With the ability to change stroke length on the fly, it's easier than ever to fine-tune one machine to handle anything. You can take on lining, shading, color packing, dotwork, fine detailing, and everything in between without ever having to pause your flow or swap machines. So does that mean adjustable stroke machines are replacing fixed stroke setups? Are the days of dedicated machines for every technique over and done with?

Not exactly. Here's everything you need to know about adjustable-stroke tattoo machines versus fixed-stroke tattoo machines (and why neither is superior to the other).

If you've been living on another planet and haven't heard of adjustable stroke tattoo machines, they're pretty self-explanatory. These machines allow you to adjust your stroke length in one machine, usually via a stroke adjustment knob or dial. Some adjustable stroke tattoo machines allow you to do this totally on the fly without pausing your session.

What About Swappable Stroke Wheels and Cams?

Not every tattoo machine with multiple stroke options is technically an adjustable stroke machine. Some machines use interchangeable stroke wheels or cams that let artists change the machine's stroke length by swapping out a physical component.

This gives you more versatility in one machine, but unlike on-the-fly adjustable stroke systems, swapping out cams is more involved. It usually means pausing, disassembling part of the machine, and installing a different wheel or cam. So, you're not locked into one fixed stroke, but you're also not getting the full "all-in-one" experience with extra parts and disassembly involved. 

Nevertheless, if you tend to stick to one stroke throughout a session—or don't mind making adjustments between tattoos—swappable stroke systems can still offer plenty of flexibility.

Stroke length refers to the distance the needle travels during each cycle of the machine. Different stroke lengths create different feels and behaviors, which is why artists have traditionally chosen fixed-stroke machines based on the type of work they’re doing.

Shorter strokes generally offer a softer, more controlled feel that many artists prefer for:

Longer strokes typically provide more give and needle force, making them popular for:

For most artists, the appeal of adjustable stroke machines is all in the flexibility. With just one machine handling it all, setup time is shorter, and overall investment is less, since you're not buying multiple machines for everything. 

Instead of having multiple machines sitting on the tray, artists can adjust one machine throughout a session to match the task at hand.

For example, an artist might start a piece with a longer stroke for solid lines and packing, then dial the machine back to a shorter stroke for smooth shading and blending — all without switching machines.

This streamlined approach is especially useful for:

Machines like the FK Irons FK One Adjust Opens a new window.are built around this idea, offering fully adjustable stroke from 2mm to 5mm. Artists can change the stroke length directly on the machine, allowing them to adapt their setup throughout the day without reaching for another machine.

For artists looking for a more budget-friendly entry into adjustable stroke, the Peak Solice ProOpens a new window. offers adjustable stroke from 2.4mm to 4.2mm, giving artists versatility across multiple techniques without the cost of a premium all-in-one setup.

Here's the thing: despite the convenience of adjustable stroke machines, fixed stroke machines aren’t going anywhere.

Some artists simply prefer a machine that's built to do one job and do it well. Stroke length is only one part of how a machine performs, and factors like the motor, drive system, give, and overall geometry all affect how it hits and feels. A dedicated liner or packer may deliver a specific feel that you can't recreate just by dialing an adjustable machine to the same stroke. Plus, there's the familiarity factor: grab your go-to fixed stroke machine, and you already know exactly how it behaves. No fiddling with settings or second-guessing your stroke length. And for some artists, that psychological comfort and familiarity is what keeps them devoted to a fixed-stroke setup.

Sometimes, artists want a liner that lines exactly how they like, a shader with the right feel, and a packer that pushes the groupings they use the most.

That's where a multiple-machine setup still makes sense. Instead of adjusting stroke as you move through a tattoo, you can grab the machine you're already super familiar with, and it's ready for the job at hand. There's less fiddling with settings, and you know exactly how each machine is going to hit before the needle touches skin.

It also comes down to specialization. A machine's stroke length isn't the only thing that determines how it performs, so setting an adjustable machine to 4mm won't necessarily recreate the feel of your favorite 4mm liner or packer. This is why tattoo machines like the Power Wand by Critical Tattoo x Bishop RotaryOpens a new window.—available in liner, shader, and packer editions—are still popular. For artists who've built their technique around specific machines, carrying a few trusted workhorses may be a lot more appealing than asking one machine to do it all.

Plus, you've always got a backup on hand if one machine dies mid-session. Never a bad thing.

Before rotary machines became the standard for many artists, coil machines were the original example of a highly customizable setup.

Artists could adjust a coil machine’s feel by changing components like springs, voltage, and the contact screw—which affects the machine’s throw and how the needle hits the skin.

For experienced coil users, this level of tuning became part of developing a personal machine setup. Many artists still appreciate the hands-on customization coils provide.

However, modern rotary machines have made that kind of customization much more accessible, with adjustable stroke machines allowing artists to change key performance characteristics without rebuilding or retuning their machine.

The answer depends on your workflow.

Neither approach is better. Different strokes for different folks, as they say.

Tattoo machines have always evolved toward giving artists more control. Adjustable stroke machines are one of the latest steps in that ongoing evolution.

For some artists, one adjustable machine can replace multiple machines. For others, a specialized fixed-stroke lineup will always feel right.

The best setup isn’t the one with the most machines or the newest technology. It’s the one that lets you tattoo the way you want to tattoo.
