Choosing the right curling iron is essential when styling any wavy or curly hairstyle, but it can be hard to differentiate between all the different sizes available. So, what kind of curl does each size curling iron create?
2" Curling iron - movement

The largest curling iron isn't really for making waves, but for adding movement through the lengths and ends of the hair, as you would with a blowout. For anyone with naturally very straight hair who doesn't want to wear it stick straight all the time, a large curling iron adds shape and bounce.
1 ½" Curling iron - big waves

For large, loose waves, a 1 ½" iron is what you need. Like a 2" iron, it's main purpose is to add movement, but the results are actual waves, rather than big curves. For a tousled finish, spritz dry hair with Advanced Hairstyle TXT IT Tousle Waves Spray before curling.
1 ¼" Curling iron - tumbling waves

Whether you want a beachy hairstyle or loose, cascading waves, a 1 ¼" curling iron will get the job done. To get waves that won't fall flat, clip your curls up to cool, then finish with plenty of Advanced Hairstyle LOCK IT Bold Control Hairspray to set.
1" Curling iron - big curls

For slightly tighter curls than a 1 ¼" iron can provide, use a 1" iron. It will create big curls that are ideal for Hollywood waves and vintage side sweeps. You can also scrunch in some Advanced Hairstyle TXT IT Deconstructing Gum to texturize the ends for a messier, more modern look.
¾" curling iron - vintage curls and updos

For bouncy curls that look great with updos and vintage hairstyles, you need a ¾" curling iron. It sets the hair into a bouncy curl that can be worn as it is or brushed out for a softer, more voluminous look.
⅝" Curling iron - perfecting natural curls

With naturally curly hair, you may want to loosen a few pieces to soften the look, or style some more stubborn sections into shape and remove frizz. A ⅝" curling iron is perfect for that as it creates a tight curl that will fit alongside the rest. It can also be used to create natural-looking, springy curls all over if you have straight hair to begin with. Just don't forget the heat protectant!
