As you start shopping for your first kayak or upgrade from your current boat, you'll have more options than ever—many different types, styles, and features to consider along your buying journey.

But without a doubt, the most critical question you should ask yourself is - what size kayak do I need for my height and weight? And are there other factors that affect the ideal kayak size for me?

Sizing a kayak is easier than it sounds, but you should take this seriously. You can buy the best, most expensive kayak on the market. But if it’s not appropriately sized for your height and weight, kayaking style, experience level, and the type of water you paddle in - you'll be fighting an uphill battle.

There is no need to play the guessing game - we're here to provide a definitive answer on which size kayak is best for you. We'll cover sizing based on height/weight, experience level, kayaking style (the type of water you paddle), and more. By the end of this article, you'll know precisely what kayak size you need. Let's get things started by discussing the different kayak dimensions.

Understanding Kayak Dimensions

Before we can answer the question of what size kayak I need for my height and weight, we must explain the different kayak dimensions. Having an in-depth understanding of these various aspects will make the process easier.

Kayak Length

This one is simple - the kayak length is the figure from bow to stern. The average size of a kayak is usually around 10' long - but as you can imagine, there are much shorter and much longer options. You can find kayaks for sale anywhere from as short as 6' up to 16'. The best kayak for a tall person will be unsuitable for a shorter person. 

But it could be more complex - you may be on the shorter end and still opt for a longer kayak because they are generally faster. On the other hand, if you're tall but want to kayak in whitewater rapids or river currents, you'll want a shorter kayak to accommodate your style.

Kayak Width

The width of your kayak is measured from the widest part of your boat. Generally speaking, the wider a kayak is, the more stable it is. The narrower a kayak is, the faster it is. This is the tradeoff you get with width. That's why you'll see that most fishing kayaks are pretty broad - to help you cast your line out and move around the cockpit without wobbling. On the other hand, Hardshell kayaks are much narrower and built for speed - but they sacrifice stability.

Kayak Weight & Weight Capacity

When it comes to weight, you need to consider the weight of your kayak relative to your weight - as each boat has a weight capacity. For example, inflatable kayaks are light - but hardshell tandem kayaks can get heavy. They range from 20 pounds on the lighter end to as heavy as 100 pounds on the heavier end. The average kayak will fall somewhere between 35-70 pounds. When sizing your kayak, you want to factor in how much it weighs because this will determine how difficult it is to load and unload the boat during transportation, whether onto a kayak trailer or roof rack.

For further consideration, check out our guides on transporting your kayak and tying it to a J rack.

Along with considering how much your kayak weighs, you need to consider how much weight it can hold. Weight capacity specs will affect your ideal kayak size - you need one to keep your body weight and any additional gear you bring. Those who plan on doing overnight trips in their kayak will need to pay particular attention to this. For example, fishing kayaks sacrifice speed and maneuverability for greater weight capacity and stability.

Kayak Cockpit Size

Because your cockpit is where you'll be sitting, you'll want to consider the ideal cockpit size carefully. Those with a larger frame will enjoy a larger cockpit that can accommodate their hips, thighs, and waist. Touring kayaks and fishing kayaks have some of the most oversized cockpits. Consider a sit-on-top kayak, which doesn't have a cockpit - giving you all the mobility you need.

Many kayakers use a boat with a smaller-than-ideal cockpit to maintain speed and maneuverability. We advise against this as it can get pretty dangerous. Say you flip over - getting out of a tight cockpit isn't easy. Plus - you want to enjoy the water, and if you feel stuck in a small cockpit, that will be tough.

Kayak Legroom

Finally, consider legroom when sizing your kayak. Those with longer legs will want more legroom. But be sure you need that legroom. If you're over 6' tall but have shorter legs and a longer torso, you may not need as much legroom as you initially suspected.

What Size Kayak Should I Get Based On Water Type?

If you plan on doing a specific type of kayaking in a particular water, you may have an ideal kayak size that doesn't quite fit your height/weight recommendations. You should consider these too. For example - the perfect kayak size for floating down rivers differs from the ideal kayak size for ocean kayaking. Let's take a look at some examples below.


When talking about kayaking in a river, we talk about something other than whitewater rapids. Check out whitewater rafts or catarafts instead if you want to take on whitewater rapids.

With that said, floating down rivers will generally require a longer kayak. All rivers have some degree of flow, so that that speed won't be your primary concern - you'll want stability and maneuverability. The ideal kayak type of this water is known as the "recreational kayak." Regarding sizing, you should look for kayak lengths between 8'-13'.  


Lakes/ponds are a unique situation in that a variety of kayak types and sizes work here. It depends on what your kayaking goals are. Do you want to go lake fishing? You'll enjoy a fishing kayak that’s shorter and wider. Do you want to explore and race around with friends? A recreational kayak or even a touring kayak will work great. These tend to be around 13' in length.


While we don't recommend it for those learning kayak, ocean and sea kayaking is an incredible adventure. In this type of water, you're facing huge waves. As such, you need to be far more focused on kayak sizes that are stable and maneuverable, similar to river kayaks. There are actual sea kayaks meant just for this type of water. But touring kayaks work great on the ocean as well. Look for a boat that's at least 12' long.

Other Factors That Affect Proper Kayak Sizing

The two main factors affecting your ideal kayak size are your height/weight and how you'll use your kayak. But other factors affect proper kayak sizing. As such, we've compiled additional information below to help you make the right decision.


Consider how you will store your kayak when it isn't being used. If you have ample garage or shed space, this won't be an issue. But if you live in an apartment or only have a 1-2 car garage, consider a smaller kayak that can easily be stored. Consider an inflatable kayak that can be broken down between uses. Folding kayaks work great for this, too.


Also, consider how you'll get your kayak to and from your destinations. There are all sorts of ways you can go about this - from trailers to roof racks and even stowing the boat in your truck bed. Considering transportation before buying a kayak will save you a headache later on.

Trust us - you want your first day taking the kayak out to be spent on something other than getting a large kayak onto your small hatchback roof. Our guide on transporting a kayak is an excellent resource for this.

Tandem Kayaking

You may start your kayak journey solo - but if you still need to, you'll want to look into tandem kayaks. These are, of course, much longer than a traditional kayak. Many of these can be converted between solo and tandem seating. So, consider these when sizing and choosing your kayak.

Will You Take Overnight Trips In Your Kayak?

If you want to use your kayak to find cool camping spots along the lake or river, you need a higher-volume kayak. This will allow you to bring overnight gear with ease. Some kayaks have a weight capacity of up to 800 lbs, whereas others are capped at around 300- 400 lbs.

But if you only use your kayaks for day use - you can sacrifice some volume for speed. Recreational kayaks are narrower but offer more performance.

What Is Your Experience Level?

If you're starting and this is your first kayak, you should steer towards the shorter and smaller end of the spectrum. Learning in a small kayak is far easier than learning in a large kayak. You can always upgrade a few years down the road and sell your smaller one - but you want to stay manageable on your first kayak and end up hating the activity because you need the proper boat.
