Have you ever bought a curling iron, only to find your curls look nothing like the tutorials? Don’t blame your technique just yet—the barrel size could be the culprit! In this guide, we’ll break down the differences between four popular sizes—1.0", 1.25", 1.5", and 1.7".  Even better, we’ll match each size to TYMO’s most-loved tools—TYMO ROVY, TYMO ROVY COMPACT, TYMO STYLUX, and TYMO STYLUX PRO—and show how their smart designs help you create your dream hairstyle effortlessly.

Why Barrel Size Matters

Think of your curling iron’s barrel size as the blueprint for your hair.

Smaller barrels (like 1.0") create tighter, bouncier curls with defined texture.
Larger barrels (like 1.7") produce soft, relaxed waves with effortless volume.

Even the same styling technique can look completely different depending on the barrel you choose. Let’s break it down by series and size.

ROVY Series – Beach Waves Made Effortless

1.0" ROVY COMPACT – Tight, Playful S-Waves

Perfect for short to shoulder-length hair, the 1.0" ROVY COMPACT delivers tight, springy S-shaped waves with a playful bounce. Its single-clamp design makes styling simple—clamp, release, and watch the waves form. With T-GLOSS technology, 9 heat settings, and a smart timer beeper, you’ll enjoy frizz-free, shiny curls that last. Lightweight and travel-friendly at just 325g, it’s perfect for creating defined, voluminous curls anywhere.

1.25" ROVY – Effortless Beach Waves

If you crave that “just-back-from-vacation” look, the 1.25" ROVY barrel creates soft, loose waves with natural movement. Often called the golden size, it’s versatile for almost all hair types. With S-shaped dent-free waves, negative ions, and T-GLOSS, your hair stays hydrated, frizz-free, and shiny for days. Quick heat-up and intuitive design make styling easy even for beginners, giving you effortless beach waves in minutes.

ROVY summary: smaller barrel = tighter S-waves, bigger barrel = soft, tousled beach waves. Perfect for natural, effortless texture.

STYLUX Series – Salon-Style Blow-Out at Home

1.5" STYLUX PRO – Full, Polished Blow-Out Curls

For medium to long hair, especially thick or frizz-prone textures, the 1.5" STYLUX PRO delivers salon-quality blow-out curls with volume and shine. Its heating comb + round plate allows you to curl, smooth, and flip hair in one step. The extended barrel and 800 million negative ions help tame frizz, seal cuticles, and give you glossy, polished results that last. Multiple heat settings and fast heat-up let you style bangs, ends, or full lengths effortlessly.

1.7" STYLUX – Relaxed, Natural Blow-Out Waves

If you love loose, effortless waves with a relaxed, “off-duty model” vibe, the 1.7" STYLUX barrel is your go-to. Recommended for long hair, its anti-tangling comb, dual-voltage travel-friendly design, and three heat settings make styling smooth and safe. The result is natural, flowing S-waves with volume and movement, giving you that coveted salon-blow-out look at home.

STYLUX summary: smaller barrel = structured blow-out curls, larger barrel = soft, voluminous waves. Perfect for polished, salon-style hair.
