20 week scan head circumference

[sarahleanne]

Just looking for comparisons ...
my sonographer said babies head was measuring big, then she measured it again and said it was "ok".
babies head is measuring at 165.9mm.
I do tend to have bigger babies and I know its hard to tell if its classed as big if I havnt given all the other measurments but just curious that's all.
Thankyou ladies

Was that the head circumference? If so, it doesn't seem big according to this link.

There should be a chart in your notes where they plot the centiles from scan measurements too.

If you scroll down on the following link, these are the same centile charts as in my notes.
