What Size 80 Really Means for Your Little One?
Ever wondered what size 80 actually means in baby clothes? You’re not alone. This guide breaks down baby clothing sizes by age, brand and region, so you’ll never buy the wrong fit again. Plus, discover how Little-ish makes sizing stress-free with curated, designer babywear that blends comfort, style and sustainability.
Because your little one deserves clothes that fit just right; not too snug, not too roomy, but perfectly “them.”
If you’ve ever stood in a baby store aisle, squinting at tags that say “70, 80, 90” instead of months, you’re not alone. Every parent has had that “wait, what does 80 mean?” moment while trying to find something cozy for their little one.
Between European sizing, US age ranges and those adorable but mysterious brand labels, baby clothes shopping can feel like decoding a secret language. And let’s be honest, nobody wants to buy that perfectly soft romper only to realize it’s two sizes too small by the time it arrives.
This guide breaks it all down, from what size 80 actually means, to how Little-ish’s artistic, European baby clothing brands fit differently, plus real-life tips on comfort, fabrics and getting the right size the first time. Whether you’re a new parent, a seasoned shopper, or just someone tired of confusing charts, this guide will help you shop with confidence and a smile.
What Size Is 80 in Baby Clothes?
Size 80 in baby clothes typically fits babies 9 to 12 months old, or those around 30-32 inches tall (76-82 cm) and weighing 20-24 pounds.
In the US, it’s close to 12-month size.
In the UK, it often corresponds to 9-12 months.
But remember, not all brands are built the same!
Some European brands (like Mini Rodini or Bobo Choses, both found on Little-ish) use height in centimeters to define their sizes. So, “80” literally means the clothing is made for a child up to 80 cm tall.
Quick size comparison:
| Size (cm) | Approx. Age | US Size | UK Size | Height (inches) |
|---|---|---|---|---|
| 60 | 0-3 months | 0-3M | 0-3M | 24 in |
| 70 | 6-9 months | 6-9M | 6-9M | 28 in |
| 80 | 9-12 months | 12M | 9-12M | 31 in |
| 90 | 18 months | 18M | 12-18M | 35 in |
| 100 | 24 months | 2T | 18-24M | 39 in |
Parent Tip:
Babies grow faster than you expect. If your child is nearing the upper end of a size range, it’s usually safer (and more comfortable) to size up, especially for cozy seasonal items like sweaters, rompers or snowsuits.
US vs UK Baby Clothes Sizing Explained
Here’s the tricky part: while US brands label clothes by age (“6M,” “12M,” etc.), European brands often use height in centimeters (“70,” “80,” “90”).
What this means for parents in the US:
If you’re shopping brands carried by Little-ish, which curates boutique European labels, you’ll often see cm-based sizes. Don’t panic! Just match your baby’s height, not age.
Example:
If your baby is around 31 inches tall, you’ll want to choose size 80.
Quick difference snapshot:
- US brands: Focus on age (months).
- UK brands: Mix of height and age.
- European brands (Little-ish): Purely height-based, for better accuracy.
Think of it this way: US sizing is like a friendly estimate. European sizing is more like tailor-made precision and that’s why many parents fall in love with it once they understand it.
Complete Baby Clothes Size Chart by Month
Finding the perfect fit starts with understanding how each growth stage aligns with clothing sizes.
| Baby’s Age | Size (cm) | US Equivalent | Height (inches) | Weight (lbs) |
|---|---|---|---|---|
| Newborn | 50-56 | NB | 20-22 | Up to 9 |
| 0-3 months | 60 | 0-3M | 24 | 9-12 |
| 3-6 months | 67-68 | 6M | 26 | 13-16 |
| 6-9 months | 70-74 | 9M | 28 | 17-19 |
| 9-12 months | 80 | 12M | 31 | 20-24 |
| 12-18 months | 86-90 | 18M | 34 | 25-27 |
| 18-24 months | 92-98 | 24M | 38 | 28-30 |
Parent Tip:
If your baby is between sizes (e.g., 78 cm tall), always size up, babies grow quickly and a slightly roomy fit gives you more wear time.
Fabric & Comfort - Why It Matters More Than Size
Sizing is only half the story. The fabric you choose impacts comfort, stretch and longevity, especially when babies have sensitive skin.
Organic vs Regular Cotton
Organic cotton is softer, more breathable and chemical-free, perfect for delicate skin.
Brands like Marmar Copenhagen and Konges Slojd specialize in organic cotton blends that feel luxurious but practical for everyday wear.
How to Choose Baby Clothes for Each Season
- Winter: Layer fleece and wool blends. Look for baby snowsuits or toddler jackets.
- Summer: Go for breathable cotton or rompers.
- Fall/Spring: Soft sweaters, organic cotton leggings, or cord jackets work perfectly.
Parent Tip:
If your baby tends to sweat easily, skip polyester-heavy fabrics, they trap heat. Choose natural fibers that breathe and flex.
Brand-to-Brand Size Guide: How Little-ish Labels Fit Differently
Shopping from Little-ish means discovering brands that care about artistry, sustainability, and individuality. But each brand interprets “size 80” slightly differently. Here’s what you need to know before adding to cart:

Expert Tip for Parents:
Always check the brand’s fit notes on Little-ish, it’s curated by experts who list real sizing advice from parents, not just manufacturer charts.
Tips for Buying Baby Clothes Online
Shopping for baby clothes online? Here’s how to avoid the “wrong size” headache:
- Measure before you buy. Use a soft tape to measure your baby’s height, chest and weight.
- Read size notes. European sizes are more height-based than age-based.
- Always check the fabric blend. Bamboo and cotton stretch differently.
- Plan ahead. Buy one size up for seasonal wear (especially winter).
- Look for adjustable features. Buttons, elastic waists and stretch cuffs extend wear time.
Pro Tip: Keep a note on your phone with your baby’s measurements, update it every month or two!

How to Care for Baby Clothes
Even the best materials can shrink or fade if not cared for properly.

- Use gentle, fragrance-free detergent.
- Wash in cold water to prevent shrinking.
