Curling Tongs for Big Curls | Large-Barrel Guide

The barrel diameter is the spec that decides your curl size. Smaller barrels make tight ringlets; 32mm and up produces those soft, voluminous bends. If you have long or thick hair, that larger barrel matters even more because it wraps more length in one pass and heats hair from root to tip efficiently. A clamp-style tong holds hair in place while you work, which is why most beginners find it easier than a wand.

What Barrel Size Creates Big Curls?

For big curls, choose a barrel of 32mm (about 1.25 inches) or larger. This size is repeatedly positioned as the threshold for large styles across manufacturer guidance and expert reviews. If you want extra-large, mermaid-style waves, look for 40mm to 50mm barrels. The thicker or longer your hair, the bigger the barrel should be — long hair comes alive with 32mm and above.

Barrel sizes translate to different looks:

• 32mm: big, bouncy curls with volume
• 38mm: looser waves with soft movement
• 40mm and up: very loose, mermaid-style waves

Barrels over 2 inches exist for the loosest, most relaxed styles. Match the barrel to the look you want, not just to the “big curl” label on the box.

How to Curl Hair With a Large-Barrel Tong

Section hair into pieces about 2cm wide and deep. Open the clamp, then flat-wrap hair around the barrel for a big, bouncy look, close the clamp to secure the end, hold for 5–8 seconds, and release. For a looser wave, twist-wrap hair around the barrel instead, hold for the same 5–8 seconds, then release.

For longer hair, start closer to the roots. Clamp at the top of the section, then wind hair down the barrel so the root and upper sections heat evenly. Curl from the roots down for longer-lasting results, and apply hairspray after styling — not before, which can make hair crispy and harder to curl.

Set the temperature to match your hair type. Fine or damaged hair needs roughly 300–350°F; thick or healthy hair can handle 400–450°F. Start at the lower end and increase only if curls don’t hold.

Notable Big-Curl Tongs Worth Knowing

Several models stand out for large-barrel curling. The ghd Curve Soft Curl Tong uses a 32mm barrel with a spring-activated lever and is designed to create big curls and soft waves. Expert Reviews named it the best curling tong for big, bouncy waves. The newer ghd Chronos Curve Grand Tong also uses a 32mm barrel and sits at the top of ghd’s lineup for soft tumbling curls with root volume on medium-to-long hair.

Budget buyers can look at the Tresemme 2806CU, which Expert Reviews called the best budget curling tong for longer hair. The Remington Pro Big Curl offers a 38mm barrel, ceramic coating, and eight heat settings from 140–210°C. The Hoson 50mm model provides the largest barrel in this group with dual voltage for travel. For a useful comparison tailored to a specific length, our roundup of the best curling tongs for shoulder-length hair covers models that perform well at that length.

Common Mistakes That Ruin Big Curls

Choosing a barrel too small for the intended look tops the list — smaller barrels produce tight curls, not big waves. A short barrel makes curling long hair harder because you cannot reach from roots to ends efficiently. Using a wand when you want clamp-assisted control also creates frustration, since wands do not hold hair in place while you work.

Heat management matters too. Starting with too much heat damages hair before you figure out what works. Apply a heat-protective product before curling, per ghd’s official guidance, and keep the tong moving so no section sits too long. Check whether your model offers dual voltage if you travel — some options like the Remington and Hoson support worldwide voltage.
