My ultrasound picture says baby is 16.7cm long. Does anyone know what the averages are for 16 weeks? I thought that seems really, really big for 16 weeks when I actually visualized it on a ruler. I thought it would be so much smaller than that.


I assume thats crown to rump, that is what she was talking about in the ultrasound?

This site http://www.baby2see.com/development/week16.html says 11-12cm.

sorry im not too sure what the average size is but if you go onto pampers website or bounty or huggies etc they have weekly updates and length is on there,,,

tell you what ill have mooch for you now

this is what the pampers website says...

Your little one is still very small - about 11- 12 cm (about 4.5 - 5 inches long and about 80 grams (about 2.8 ounces) - and the cushion of amniotic fluid can make it difficult to feel movement at this time.

In What To Expect When You're Expecting :


16 Weeks: With a whopping weight of anywhere from 3-5 ounces and a length (crown-to-rump) of 4 to 5 inches, your baby is growing up fast.

20 Weeks: You've got a baby the size of a small cantaloupe in your melon-size belly this week, about 10 ounces and 6 1/2 inches long


16.7cm = 6.5 inches.


I am going to hurt someone if they told me the wrong dates again.

PeanutBean

It does seem quite a big difference but then baby growth can be variable - I just don't know variable! But surely having measured it that would be what they used to date you right?

That is probably total length, not crown to rump length. My baby is ten inches at 21 weeks total length, so 6.5 inches total length at 16 weeks sounds about right.

Hmmm I'm not sure. I asked two girls around here that are pregnant now and getting theirs at the same hospital I had mine...one said hers was 11.7cm and one was 12cm...so either way, its still a lot bigger, total length or not

Im looking at my notes to find out what mine was at 18+5....

Which one is it??

BPD, HC, AC, FL, or HL??

They are all in mm!!

PS::: On my 13 week scan CRL??? is that crown to rump??

It says 66mm!!

Hold on....*flicks out my handy metric convertor* That would beee....2.6 inches. So, that was 3 weeks before what I'm supposed to be? Mine just says straight up 16.7cm Length...but she only ever mentioned crown-rump in the ultrasound, never total length. I didn't think they even started doing total length until much later than 16 weeks.
