Hair Straightener Sizes

If you are wondering “what size hair straightener should I get to curl my hair“, this article will attempt to help with that answer. A size of a flat iron, size referring to the width of its plates, is one of the things to consider when buying a hair straightener.

Each category of size is meant for certain type of hair as regards the hair length, texture, state of health, etc. However, this is not to say once you know your hair type, flat iron size is the only thing to consider when buying a flat iron. There are other factors to look at when selecting the perfect flat iron for you.

What Size Hair Straightener Should I Get

Hair straightener sizes vary from 0.5 inches to 2.5 inches to cover different hair sizes. Any thing smaller than 0.5 inch would be hard to find. A 1/4 inch flat iron is hard to find and there are not many brands that make it hence it is not common or readily available like 0.5 inch flat iron.

Below we will look at different sizes of hair straighteners starting with a 1/2″ one and also indicate what size of hair it would suitable on.

Though small, a good brand will have the best qualities of a good hair straightener. It can be made from ceramic or titanium, with dual or universal voltage. It can heat up to high temperatures in a short time. It can also have a swivel cord for ease of use. Let us look at couple of examples to demonstrate this.

“The size is perfect for travel and it gets really hot really fast. I only give it 4 stars for two reasons – for one, the plates don’t seem to be as ‘slick’ as other flat irons; they don’t slide over my hair as smoothly as I’d like. Second, there is no temperature control which isn’t a deal breaker since I like my flat irons really hot but every now and then it’s helpful to turn the temp down. Still the best travel straightener ever!”
