The “magical” clothing sizes for babies & children – why 86 and 104 are especially interesting
New parents – or anyone wanting to gift clothing for kids – know the struggle: you find something beautiful, but after just a few weeks it’s too small or fits perfectly, but in the wrong season. A classic gifting fail.
But there are sizes many parents describe as “magical”, because they last much longer than others: size 86 and later size 104. Why this happens – and why these sizes are especially worth it for higher-quality or special gifts – you’ll discover here.
Why size 86 is so special
-
Slower growth: In the first year, babies grow about 25 cm on average. From the second year, growth slows to just 10–12 cm per year (see WHO Child Growth Standards, 2006). That’s why many children stay in one size much longer – often in size 86.
-
Transitional size: 86 marks the step from baby to toddler clothing. These garments are often cut more flexibly, with elastic waistbands or adjustable straps, and therefore last longer.
-
Longer usage: Many parents report that their children wear size 86 from around 12 months up to 2 years – much longer than earlier sizes.
Why size 104 is also interesting
After size 98 comes 104 – and this size often lasts longer, too. Why? Between the ages of 3 and 4, children’s growth slows down again. Studies such as the German Health Interview and Examination Survey for Children and Adolescents (KiGGS, RKI 2014) show that the growth curve flattens during this stage. Many kids therefore wear size 104 across several seasons.
For parents and gift-givers, this means: investing in high-quality pieces for this size really pays off.
What gift-givers should consider
If you want to give clothing to new parents or young children:
-
Choose the “magical sizes”: 86 (around 1 year) and 104 (around 3 years) are safe and long-lasting investments.
-
Think about the season: A cute summer dress in size 86 given in October will probably never be worn. Better choices: transitional pieces, basics, or vouchers.
-
Quality over quantity: In these longer-lasting sizes, high-quality, durable materials are worth it.
-
Go for adjustable clothing: Elastic waistbands, straps, or grow-with-me cuts extend usability even further.
Sustainability in mind
Long-lasting sizes mean less frequent shopping – and therefore less consumption, less waste, and less stress for parents. Especially for expensive or special pieces, it’s wise to invest in these “magical phases.”
Conclusion
When it comes to baby clothing, it pays to think beyond the “classic” gifts. Size 86 is a real gamechanger – lasting much longer than earlier baby sizes. Later, size 104 takes over this role and often lasts across several seasons.
👉 For new parents: plan consciously, invest in basics, and take advantage of these longer phases.
👉 For gift-givers: choose long-lasting sizes – so your gift will truly be used and remembered.
