What is the difference between golf irons?

Answer 1

A 9 iron is shorter, and has a little more added loft to it, so you can hit the green and not go over. A 7 iron is a mid iron, and is a little longer, and the loft is less than a 9 iron so you can have a little more added distance than a 9.

Answer 2

They start at a 3 iron and go to a wedge, as a general rule, as you go down the set 3 iron to wedge the clubs get shorter and have more loft.

Answer 3

Taylormade R7 irons became available in 2004. Taylormade R9 irons were introduced in 2010. R9 irons allow one to hit the Golf ball much farther than the R7 iron.

Answer 4

One has a higher loft than the other
