‘But what plate size is right for me?’

Well, experimenting with different-sized tools can be fun! 😜 But seriously, if you’re unsure whether to reach for a wide or thin hair straightener, assessing your hair type and needs is key.

A narrow flat iron is a great choice for polishing fine or mostly straight hair that just needs a quick run-through.

And if you have the travel bug, a thin hair straightener packs conveniently without wasting precious luggage space. More room for all your killer outfits!

A wide plate hair straightener offers fiery power. If you have coarse, thick, or curly hair, then wider plates move through your mane more easily.

However, wider plates tend to reach a higher temperature. So, if you already have damaged locks from colouring or generally dry hair, you need to be careful handling the heat.

Unsure of what wide or thin hair straightener to pick? We’ve done the hard work for you with our guide on hair straightener sizes.


A wide-plate, thick-hair hero

For coarse or thick hair, wide plate hair straighteners are a must. It's simple physics: larger plates apply more heat to your hair.

No need to feel overwhelmed by your mane of hair: the Silver Bullet Keratin 230 Ceramic Wide Plate Straightener has you covered with 38 mm ceramic plates to get through coarse or unruly hair. And for those who have ever walked out of the house and freaked, thinking you left your straightener on, this wide plate hair straightener goes into a safety sleep mode after 30 minutes of idling. Disaster averted!

A wide plate hair straightener makes styling larger sections of hair easier, which is great news for those with a bounty of thick locks.

Because thick and curly hair tends to be drier by nature, do use a heat protectant to support your locks and prevent straw strands during styling.


The narrow flat iron: an all-rounder

When you’re comparing wide or thin hair straighteners, you’ll see that 1-inch straightener plates are the most common option, as they work for most hair types.

So, what’s the difference between all those same-size appliances? It’s those extra details that’ll elevate your straightening sesh from hot-iron hell to waves of glory.

The Hot Tools Black Gold Evolve Flat iron is a narrow flat iron that offers a rotating temperature dial to cater to all hair types. Another plus is its durable Titanium plates and a Micro Shine finish. I know we’re getting into the nitty-gritty details now, but the result is the smooth, sleek look I’m sure you’re totally here for. 

*PRO TIP* To reduce heat damage, use a narrow flat iron on one small section at a time. This way, you only need to glide that straightener through once to get it right. Once you’re looking flawless, finish your style with hairspray and serum to keep your tresses straight all day long.


The future of hair straighteners

Remember when we used to stand in line for the latest iPhone release? Those days are over—for now. 😒 But here's another space-age gadget you can play with in the meantime: the Dyson Corrale Hair Straightener.

This straightener has first-of-their-kind flexible plates (whoa!) that touch every strand, letting you style with fewer passes and less heat. (But really, how long do we have to wait for a phone/straightener combo?)

Great for all hair textures and types, this narrow flat iron offers 3 precise heat settings—165°C, 185°C, and 210°C—to suit your needs. The Corrale’s innovative Manganese and Copper Alloy plates are engineered to the width of a human hair to style faster and more effectively.

The cool thing about these narrow hair straighteners is the integrated sensor system, which checks and adjusts the temperature of the plates 100 times a second. More often than you check your phone? Sounds intense, I know! But this means you can be confident that the temperature showing on the dial is the temperature on your hair. And it’s perfect for you hairstylists with control issues. 😉


Because we love a good aesthetic

You know you want to show this rose gold hair straightener on your IG stories ASAP! Along with clever touchscreen temperature controls, the Silver Bullet Titanium 230 Supernova Rose Gold features 25 mm Titanium plates for smooth styling.

Designed with variable temperatures from 110°C to 230°C, this narrow hair straightener can be used on all hair textures. Plus, it actually remembers your last used temperature setting—genius! Remember to show your hair some love by spritzing on or massaging in a thermal protectant first. This’ll create a barrier between your locks and the heat. To give you some peace of mind, this straightener also comes with a 2-year manufacturer’s warranty.

When you’re considering a wide or thin hair straightener, an important factor is being able to maneuver when styling. A wide plate hair straightener can feel clunky. So, if you need the freedom to create that perfect selfie-worthy look, then a narrow flat iron is for you.


It’s cute but it packs a punch

Measuring only 6 inches in length (only?), the CLOUD NINE The Micro Iron is perfect for short hair, fringes, and to-the-root styling. Infused with Sericite and Tourmaline, the plates on this beauty help seal the hair’s cuticle and lock in moisture. In other words: goodbye frizz, hello shiny, on-point hair.

The Micro Iron also makes an ideal travel companion. When you’re on holidays, the last thing you need is to be pent up in a hotel room all day doing your hair and then waiting for everything to cool down again. I mean, if you’re going to be pent up in your room all day, I can think of better ways to spend your time!

This narrow flat iron is hot within 20 seconds, ready for touch-ups or short hair styles. Caveat for babes with thick or long locks: this straightener will have a hard time taming your beautiful tresses, so you should opt for a bigger wide or thin hair straightener.

As soon as you're finished using your Micro Iron hair straightener, you can clasp the plates back together, slip on the protective heat guard, and throw it into your luggage. 



We think you’re 100% ready to take on the world of straighteners now! Remember, when choosing a hair straightener, do your recon to find out what’ll work best on YOUR hair. We totally get that it can be tempting to reach for the cheapest option. But this approach could lead to undue damage or breakage.

No matter what wide or thin hair straightener you choose, always prep your hair beforehand with a thermal protector of your choice—no excuses! And treat yourself to a luxe hair mask once a week for some mane hydration.
