A quick story-style check

Imagine you’re gifted a cute romper from a European brand and the tag only says “70.” You can think: “Okay, this should fit a baby around 6–12 months, about 70 cm tall, and around 16–20 pounds.” If your baby is long for their age or growing fast, many parents size up to 80 so the outfit lasts longer.

Practical tips

Always check the brand’s own size chart, because some run small or large.
If baby is between sizes (for example 68–71 cm), going up to the next size (80) usually gives a more comfortable fit and room to grow.

For gifts, size 70 is usually safe for a baby who is currently around 4–8 months, since they’re likely to grow into it even if it’s a bit big at first.
