The Quick Answer: What is Size 80 in Baby Clothes?
Let’s get straight to the point. European baby clothes sizing, including size 80, is based on your baby’s height in centimeters.
Size 80 fits babies who are up to 80 centimeters (about 31.5 inches) tall. This is the key fact to remember.
Age can help as a rough guide, but it’s not very exact. For a quick reference, size 80 usually matches a US size 12-18 months or a UK size 9-12 months. Your baby’s actual height is what really matters though.
Here’s the simple breakdown:
- European Size: 80
- Corresponds to Baby’s Height: Up to 80 cm (31.5 inches)
- Typical Age Range: 9 to 12 months
- Common US Equivalent: 12-18 Months
- Common UK Equivalent: 9-12 Months

A Note on Weight
Height drives European sizing. A baby’s weight also affects how clothes fit.
Size 80 usually works for babies weighing about 19-24 pounds (around 8.5-11 kilograms). If your baby is heavier for their height, you might need to size up for comfort, especially in tight-fitting clothes like bodysuits.
The “Why” Behind the Number: Understanding the Logic of European Sizing

European sizing makes more sense than the confusing age-based systems used in the US and UK. The number on the tag shows the maximum height in centimeters that the clothes will fit.
When you see “size 80 in baby clothes,” it simply means the item fits a baby up to 80 cm tall. This way of sizing takes out the guesswork of buying for a “12-month-old” who might be bigger or smaller than average.

Is Your Baby Long & Lean or Short & Chunky?
This question matters a lot when checking the size chart. A baby’s body type changes how size 80 will fit.
For example, a tall, lean baby who is exactly 80 cm might fit perfectly in size 80 clothes. But a shorter, chunky baby who is only 77 cm tall might need size 86 to fit comfortably around the middle.
The length might be too long, but the overall fit will be better.
The Fabric Factor: Stretch vs. Woven
The material makes a big difference in how clothes fit. Not all fabrics work the same way.
Always check what the clothes are made of:
- For Stretchy Fabrics (like jersey onesies, leggings): These materials stretch and give, so the size on the tag is usually accurate.
- For Woven Fabrics (like denim, dress shirts, corduroy): These don’t stretch much. We suggest sizing up in these items, especially if your baby is near the top of the size range.
A size 80 denim jacket will fit much tighter than a size 80 jersey sweatshirt.
Don’t Forget the Diaper!
This small detail matters a lot. The type of diaper affects how pants, rompers, and bodysuits fit.
Disposable diapers are slim. Cloth diapers are bulkier.
If you use cloth diapers, you’ll probably need to size up in pants to make sure there’s room around the hips and crotch.
How to Measure Your Baby for a Perfect Size 80 Fit

To use European sizing well, you need to measure your baby correctly. It’s easy and quick.
Step-by-Step Measurement Guide
- Lay Them Flat: Measure your baby while they’re lying down on a firm, flat surface.
- Measure Height/Length: Use a soft tape measure. Straighten their leg gently and measure from the top of their head to their heel.
- Pro-Tip: For wiggly babies, lay them on paper. Mark the paper at their head and heel, then measure between the marks after they move.
- Measure Chest & Waist (if you want): For jackets or dresses, measure around the fullest part of their chest and tummy. This helps with babies who are rounder.
You can check the World Health Organization (WHO) growth charts to see how your baby compares to average growth. This can help you predict when they’ll need to move up to size 86.
Brand Variations: Why a Size 80 Isn’t Always the Same
The European system is good, but brands still fit differently. One brand’s size 80 might not fit the same as another’s.
European Brands vs. American Brands
There’s a pattern in how brands fit. Many European brands (like H&M, Lindex, or Polarn O. Pyret) cut their clothes longer and slimmer. This works well for tall, lean babies.
American brands often make wider, roomier clothes for the same age. This is a general rule that helps when shopping from different countries.
Even within Europe, a Swedish brand might fit differently than a German or French one.
Our Rule of Thumb
After years of dressing babies, we have one simple rule that always works. When you’re not sure, pick the bigger size.
“When in doubt, size up.”
Babies grow very fast. Clothes that are a bit too big will fit soon and last longer. Clothes that are too small are useless right away.
Sizing up gives you extra time and better value for your money.
Conclusion: Shop with Confidence
Baby clothes sizing can seem hard, but European sizing makes sense once you understand it. The confusion about “what size is 80 in baby clothes” goes away when you know it’s about height.
With this knowledge, you can shop confidently anywhere.
