If you’re buying earrings for babies or children, you may have seen the term 20G or 0.8mm and wondered what it means. Choosing the right gauge is actually very important because it affects comfort, safety, and how well the earrings fit.
Let’s explain it in simple terms.
What Does Earring Gauge Mean?
The gauge refers to the thickness of the earring post — the part that goes through the ear. The higher the gauge number, the thinner the post. For example:
- 22G = 0.6mm (very thin)
- 20G = 0.8mm (standard size)
- 18G = 1.0mm (slightly thicker)
For most standard ear piercings, earrings are usually between 20G and 18G, with 20G being the most common size for regular stud earrings.
Why 20G (0.8mm) Is Best for Children
There’s a reason why most children’s earrings are made in 20G — it offers the best balance between comfort and durability.
20G earrings are:
- Thin enough to be comfortable for small ears
- Thick enough to be strong and not bend easily
- Suitable for newly pierced ears
- The most widely used size in standard earrings
This size is considered ideal because thicker earrings can cause discomfort, while thinner earrings may bend or break more easily.
What Happens If the Gauge Is Too Thick or Too Thin?
Choosing the wrong gauge can cause problems:
- Too thick: Can cause pain, stretching, or irritation
- Too thin: Can bend, break, or irritate the piercing
- Wrong size: May not fit properly in the piercing hole
This is why most jewellers and children’s jewellery brands use 20G (0.8mm) as the standard size for kids’ earrings.
20G vs 18G – What’s the Difference?
Both sizes are common, but they are used for different reasons:
| Gauge | Thickness | Best For |
|---|---|---|
| 22G | 0.6mm | Very delicate earrings |
| 20G | 0.8mm | Children & standard earrings |
| 18G | 1.0mm | Heavier earrings |
| 16G | 1.2mm | Cartilage piercings |
Most children’s stud earrings are made in 20G because they are lightweight, comfortable, and fit most standard ear piercings.
Final Thoughts
When buying earrings for babies or children, the safest and most comfortable choice is 20G (0.8mm). It’s the industry standard for a reason — it’s comfortable for small ears, strong enough for everyday wear, and fits most standard piercings.
If you’re ever unsure what size to choose, 20G is the safest choice for children’s earrings.
