The off-road industry is booming, and there’s no better time than the present to join the fun. If you want to ride along on your very own ATV (also known as a four wheeler), you’re in luck! There are now more options than ever when it comes to ATV size and power. With so many four wheelers on the market, your perfect machine is out there… somewhere. You might just need a little help finding it.

As always, SuperATV is here to lend a helping hand. Let’s talk about the different ATV sizes that are out there and find out which one is perfect for you.

Quads like this Polaris Sportsman are popular for off-roading, but how do you know which is right for you?

What Are the Different Four Wheeler Sizes?

When you’re looking at the physical stature of ATVs, you’ll quickly notice that these machines come in all different sizes. This is important for a couple of reasons. The first reason is everyone is different. A shorter individual might not be very comfortable sitting on a massive four wheeler. The same goes for a tall person on a smaller model.

The other reason to be aware of your ATV’s size involves trailering. If you plan on transporting your four wheeler, either in the bed of your truck or on a trailer, you’ll need to know the length and width of that machine to make sure it will fit.

Common ATV Dimensions

So exactly how long and wide are ATVs, anyway? While there is quite a bit of variance, most four wheelers fall into specific size categories.

We’ll start with some general measurements. The average length of an ATV is around 83” and the average width is 47”. Most machines you come across will have measurements close to this.

But not all of them! Check out these ranges, broken down by ATV type. This should give you a better grasp of how big these machines are and what size quad might be best for you.

  • Youth ATVs: 50-60” long, 30-40” wide
  • Small ATVs: 65-70” long, 40-43” wide
  • Standard ATVs: 70-85” long, 43-45” wide
  • Large ATVs: 85-95” long, 45-48” wide

Engine Displacement in ATVs

But when talking about ATV size, most people aren’t referring to the physical length and width of that machine. Most riders compare ATV size by their engine displacement. This number is given in cubic centimeters (cc) and refers to the volume of your engine. ATVs with bigger cylinders and pistons will have higher displacement, thus more power.

We’re not kidding when we say there’s an ATV for everyone. There are small 50cc youth ATVs, aggressive 1000cc sport ATVs, and everything in between. It’s important that the machine’s displacement match the experience level of the rider. Jumping on something too fast and powerful can be dangerous.

Even though four wheelers are typically categorized by engine displacement, four wheeler size can also refer to actual physical measurements. Youth ATVs are obviously smaller and lighter, and adult ATVs are available in mid-size and full-size versions.

Some factors to consider when deciding which size ATV is right for you include your age, height, and weight. You’ll be spending a lot of time on this machine, so you want to be comfortable and not too cramped. For adults up to 5’10”, a smaller ATV (around 400cc) should be a good fit, unless you have a specific reason for needing something more powerful. And for taller riders, we recommend looking at 500cc machines and higher.

Breaking It Down by Level of Expertise

The most crucial thing to consider when choosing your ATV size is your experience level. Like we mentioned earlier, it would be super dangerous to hop on a 1000cc four wheeler on your first rodeo.

These are by no means official safety guidelines, but here are some loose recommendations:

  • 50-70cc: kids 12 and younger
  • 70-150cc: kids 16 and younger
  • 150-300cc: experienced teens, smaller adults, brand new riders
  • 300-500cc: easy trail riding, new riders, light work
  • 500-700cc: hard trail riding, larger adults, heavy work loads
  • 700-1000cc: racing, deep mud, hill climbing

For most adult riders, something in the 500-700cc range will offer more than enough power to tear up the trails and have a good time.

A 1000cc engine might sound exciting, but unless you’re a professional racer or someone who regularly takes on difficult off-road challenges, you probably don’t need a big four wheeler with that much power.

What Will You Use Your ATV For?

In addition to your physical size and experience level, another thing to consider when choosing an ATV size is what you’ll be using it for.

Most off-road vehicles fall into one of three categories: sport, utility, or somewhere in between.

Sport ATVs are built for fun. These machines are designed with performance in mind, so they’re usually on the lighter side and offer more power and better handling. In terms of looks, sport ATVs tend to have a more aggressive appearance. They’re great for jumping, racing, and cornering.

Utility ATVs are made for working hard. They’re usually heavier with a higher towing capacity. Their ability to pull trailers, push plow blades, and haul heavy loads make them popular on farms and jobsites.

And then you have the “in between-ers”: sport-utility ATVs. This category is arguably the most popular because these machines are equipped to do it all. You can use it for towing or landscaping during the day and then take it out for an evening joyride when you’re ready to unwind.

If your main reason for buying a four wheeler is to have fun, a mid-size ATV might be the perfect fit. You’ll have enough power to tear up the trails and haul your hunting or fishing gear if need be.

But if you want something that can put in some work—think landscaping, farming, or snow removal—or dominate some serious trail challenges, a large ATV would be more helpful.

What Features Will You Need?

It’s not all about ATV size. There are a host of other features and accessories to consider when finding the perfect machine to suit your needs.

Here are some other decisions you may have to make when shopping for a new (to you) ATV:

  • Carbureted vs. Electronic Fuel Injection (EFI)
  • Air cooled vs. liquid cooled
  • Single cylinder vs. twin cylinder
  • Two-wheel drive vs. four-wheel drive
  • Power steering vs. no power steering

If there are specific features you’re looking for in an ATV, you always have the option of adding aftermarket parts and accessories to meet your needs:

  • Specialized wheels for technical riding
  • Storage racks for hauling gear
  • Winches for getting yourself (and your buddies) unstuck
  • Bumpers for extra machine protection on rough trails
  • Snow plow for clearing parking lots or driveways
  • Lights for night riding
  • Speakers to bring your favorite tunes along for the ride

Deciding which parts and accessories to invest in can be overwhelming. To get you started, we’ve put together a list of ATV upgrades that will make your quad better.

The answer to the question “What size ATV do I need?” isn’t as cut and dry as you might think. Whether you’re looking at engine size or physical measurements, there are several factors to consider when making a decision.

Hopefully this helped steer you in the right direction! If you’re still undecided about what kind of vehicle to buy, check out our ATV vs. UTV breakdown. Once you’ve made your pick, all that’s left to do is buy that machine and hit the trails.

        I need a 4×4 that will fit in my Tacoma bed, which limits me to a width of no more that 44 inches. A 350 to 500cc engine is my target. Possible?

          Hi Blake! We think it’s definitely possible to find something within that range. The brand-new Arctic Cat Alterra fits those specs, with a 450cc engine and 44″ width. If you want to buy used and look at some older models, your options open up even more. The Yamaha Wolverine 350, for example, comes in at just under 42″ wide. Good luck in your search and thanks for reading!
