Exactly what those people said, go to a golf course. When you do, dont just get a proshop worked to help you. get the golf course pro, someone who knows golf like the back of his hand to help you. Anyone can tell you what you need, but you need someone who knows what it is exactly you need.

I am guessing you are a woman/girl - and "women's/lady's" golf clubs are designed/intended for people roughly between the heights of 5'0" to 5'6" tall.
Someone at your local golf shop should be very helpfull in helping you make an informed decision.

The best information you will receive will be from a golf club or course teaching pro, or a shop that specializes in fitting people to the correct size clubs.
It's not only your height, but also your stature to be taken into consideration.

Regular length ladies shafts should be all good for you.

Yeah, regular ladies clubs should be fine. It wouldn't hurt to get fitted though.
