Do you ever think to yourself, “Which size curling iron should I be using?” Sometimes it can be confusing when some curling iron sizes look so similar. ¼ of an inch can make a difference between a fun, flirty beach wave and big, bouncy curls. When deciding what size curling iron you should use you want to take your hair length into consideration. So, for instance, if you have shoulder-length hair and you use a 1″  curling iron your hair will wrap around the barre; about 4-5 times creating a wavy style. If you used a ¾″ iron on the same length hair you would get a deep wave/curlier look. If you used a bigger curling iron like a 1 ¼″ you would get a looser, larger bend/wave.  

How Does A Curling Iron Create Curl?

A curl is created by wrapping your hair around a hot curling iron barrel. Every time your hair is wrapped around the curling iron one time that creates a curl. So the more your hair wraps around the curling iron the more curl you will create. The less your hair wraps around a curling iron the less curl you will get. That’s why hair length plays a role in which curling iron size to pick for the hairstyle you’re trying to achieve

2″ Curling Iron

This is a mighty big curling iron. If you’re just looking for a very loose wave or just big bouncy ends, with a slight curl you want to get yourself a 2″ curling iron. 

This is a good curling iron size for long hair and the longer your hair is, the more wave you will get out of it. Using a 2″ curling iron on shorter hair will create volume and bend, not a wave or curl.
