Does Size Really Matter?
Of course, it does matter!
Otherwise, think, why would you see flat irons of different sizes in the market. There has to be some reason, right?
Some flat irons have longer plates, while others have shorter ones. Some have wider plates, while others have narrower plates. Also, the weight of every flat iron is different.
And to identify the correct hair straightener size for your hair, you’ll need to determine your hair texture, hair length, and your purpose of buying the flat iron (do you want to use it for curling and straightening or only for straightening?).
Once you find the answers to this question, you can quickly figure out which one is right for you.
For example, if you’ve got short, chemically treated, or fragile hair, a short flat iron would be ideal for you. Alternatively, if you want to straighten long, thick curly hair, you should go for a flat iron with wider plates and comfortable gripping but less weight.
That said, have a look at the table below for a deeper understanding of which hair straightener will suit your hair.

Now that you know the size of straight irons available in the market let’s see how to pick the right one for your hair. Below is a detailed description of straightening irons of each size and their purpose.
Small Flat Irons
Small straightening irons are those with a plate width between 0.5 to 0.75 inches. They are tiny and best for precision. Small flat irons are recommended for short hair, men’s hair, or tight curls. Plus, you can bring them closer to your scalp without the fear of getting burnt.
Again, they are light and compact. Hence, you can carry these straighteners in your bag while traveling.
However, as the plates are narrow, you need to work on small sections.
Standard Flat Irons
Standard flat irons are the most commonly chosen flat irons. They come in 1-inch wide plate sizes and suit almost every hair type and hair length. Plus, they are ideal for creating medium curls, waves, and even twists.
Besides, most brands manufacture 1-inch hair straighteners. That means you get tons of options to choose from.
Larger Flat Irons
Hair straighteners of plate size 1.25 inches or above are large flat irons. These straighteners can get your hair straight quicker.
Especially if you have long, thick, curly hair, you should get such straighteners. That’s because the broader plates let you work on a wide section of hair at a time. So, your hand doesn’t have to suffer for long.
However, larger straighteners have a large body and are heavier. Therefore, go for one which has a comfortable grip.
