A lot depends on the size of the wielder as well. Weapon nomenclature is by no means a precise science, and a "two-handed sword" could have a blade length of anywhere from around 36"-60" and a weight of 5-8 lbs. More usually they would be on the shorter and lighter end of the scale, though. The word "claymore" is used most frequently to describe two types of Scottish sword from the very late medieval to early modern period. As noted, however, it translates to "big sword" or some such thing and so was probably initially used to describe a sword larger than was normal.
