Hammock length is important for two reasons: first, you want to be sure that it will be long enough for you to comfortably lie in; and second, you want to be sure that it will be able to support your weight. Hammock lengths vary much less than widths, and most of them will be able to accommodate people of average height. However, if you are taller than average, you may want to look for one that is 2 feet longer than your height. In addition to length, width is also important.nnHammock widths vary more than lengths, and the right width for you will depend on how you plan to use it. For example, if you plan to use your hammock primarily for lounging, then you will want it to be at least 5 feet wide. However, if you plan to use it for camping, then you may want one that is only 4 feet wide. The bottom line is that the right hammock for you will depend on how you plan to use it. Be sure to take into account both length and width when choosing a hammock.
