Again, this really depends on what you're looking for from your kayak and how tall you are when it comes to longer vs shorter kayaks. If you're a tall person, chances are you're going to need a slightly bigger kayak to ensure your legs can fit inside. But there are other things to consider when it comes to kayak length. And that's speed vs. maneuverability. Smaller kayaks tend to be easier to control and a lot more agile. While longer kayaks can cut through the water a lot easier, which means they can go faster with less effort. Think about what you want from your kayak to determine what length you need.
