Your height does not factor into the kayak you choose in the same way that it does your paddles. As long as you are using your kayak for its designed purpose — fishing, whitewater exploration, recreational touring — you should be comfortable. Your weight, however, should factor into your kayak decision. Each kayak comes with a weight capacity limit. The good news is that there are several different types of kayaks to fit all body types and weights. Always be sure you check the weight limit before making your purchase. When doing so, you must remember to factor in the weight of your gear. A good rule to keep in mind is to take the weight limit number and subtract 125 to 150 pounds from it to account for your equipment. Then, check that your current body weight fits within that limit.
