Hot Roller Sizes: How to Choose the Right Size for Your Style
When it comes to hot rollers, size matters, but bigger doesn't necessarily mean bigger curls.
Roller diameter helps determine whether you'll get loose volume, soft curls, flipped ends, or a full-bodied blowout. And you don't have to use the same size throughout your entire set.
The Amplifying Hot Rollers include five 1.5" rollers and five 1.75" rollers, giving you two sizes to mix, match, and customize depending on the look you're going for.
So, which size should you reach for? Let's break it down.
1.5" vs. 1.75" Hot Rollers: What's the Difference?
As a general rule, larger rollers create a looser shape and more body, while smaller rollers create more noticeable bend and curl.
With the RevAir Amplifying Hot Rollers:
1.75" Rollers: Think Volume + Body
Reach for the larger 1.75" rollers when you want:
- Crown lift
- Full-bodied volume
- Loose movement
- A rounded blowout shape
- A softer bend through the lengths and ends
These are your go-to rollers when the goal is less about creating a defined curl and more about giving the hair that big, airy, fresh-blowout feel.
1.5" Rollers: Think Curl + Movement
Reach for the 1.5" rollers when you want:
- Soft curls
- More noticeable movement
- Flipped or rounded ends
- Face-framing shape
- More definition through the lengths
Because the hair wraps around a smaller diameter, the finished shape will generally have more bend than it would with a larger roller.
Want Crown Lift?
Go big.
Place the 1.75" rollers at the crown where you want additional height and body.
And you don't need to set your entire head just because your roots have fallen a little flat. A few strategically placed larger rollers can help bring volume back to the areas that need it most.
Want Soft Curls?
Reach for the 1.5" rollers.
The smaller diameter creates more bend through the hair, making them a great choice when you want your roller set to produce visible curls rather than primarily volume.
Want to Bend or Flip the Ends?
Your roller size can change how dramatic that bend becomes.
Use a 1.75" roller for a softer, rounded finish or a 1.5" roller when you want the ends to have a more noticeable bend.
Then decide which way you're going.
Roll under for a smooth, rounded finish, or roll outward when you're feeling the flip.
Want a Big, Bouncy Blowout?
Use both.
A mixed roller set lets you put volume where you want it and more movement where you need it.
Try 1.75" rollers through the crown and upper sections for body, then incorporate 1.5" rollers through the lengths or around the face for additional movement.
The result doesn't have to be perfectly uniform. In fact, using both sizes can help create the varied movement that makes a blowout feel soft, full, and effortless.
Want to Refresh Yesterday's Style?
This may be our favorite reason to keep hot rollers within reach.
You don't always need to start over.
If your blowout still looks good but the crown has fallen flat, add a few 1.75" rollers where you want the lift back.
Lost some movement around your face? Reach for a 1.5" roller.
Ends need a little help? Reset only those sections.
Add crown lift, bend the ends, refresh yesterday's style, or go full blowout.
That's the beauty of having options.
Do You Have to Use the Same Size Roller Everywhere?
Nope.
Think about hot rollers as individual styling tools rather than a set that has to be used exactly the same way every time.
You can use all one size. You can mix both sizes. You can set your whole head. Or you can use two or three rollers exactly where you want a little more volume or movement.
Your roller set should work for the style you're creating, not the other way around.
Which RevAir Hot Roller Size Should I Use?
Here's the cheat sheet:
- For crown lift: 1.75"
- For big, soft volume: 1.75"
- For a loose blowout shape: 1.75"
- For soft curls: 1.5"
- For more movement: 1.5"
- For a subtle bend at the ends: 1.75"
- For a more noticeable bend or flip: 1.5"
- For a full, bouncy blowout: Mix both
- For a quick refresh: Choose the size based on what needs a boost
Want More of Your Favorite Size?
Once you figure out which roller size you reach for most, you can build your set around the way you actually style your hair.
Additional 1.5" and 1.75" Amplifying Hot Rollers are available separately, so you can add more of either size to customize your set.
Love a big, voluminous blowout? Add more 1.75" rollers.
Prefer more curl, movement, or flipped ends? Stock up on 1.5" rollers.
Or add a few of each, so you have enough rollers to mix sizes throughout a full set.
Your original set gives you both sizes to work with. From there, you can build the roller lineup that works best for your hair, your styling routine, and the looks you create most often.
More Sizes. More Ways to Roll.
The Amplifying Hot Rollers include five 1.5" and five 1.75" velvet-flocked rollers, so you're not locked into one type of finish.
Use the larger size for body. Reach for the smaller size when you want more bend. Mix them for a full blowout. Or grab just a few when yesterday's style needs a little something.
Because some days call for a full set.
Others just need a little lift.
