Worried about baby measurements (24weeks)

[Stardust3484]

Hi all.
I had a 4D scan last week and since then, the measurement of length that was given to me has me worried. She said he is 16cm. I'm confused as I thought after so many weeks it wash measured crl head to heel, not crl. I have a growth scan booked soon but I'm constantly worrying.
Anyone who has had this or having this, I'd appreciate any input.

Thankyou

Growth scans don’t measure head to heal, it would be virtually impossible to get those measurements as often the baby is curled up and moving. Most trusts input the head circumference, abdominal circumference and femur length into the computer and the software will generate an estimated weight of the baby and plot each measurement onto a centile chart. I’m sure she would have told you if this measurement was not equal to your dates so I wouldn’t worry.

Thankyou for your response. The scan was privately booked so my partner could come to a scan due to covid restrictions. It was only a wellbeing scan. I'm just thinking the worst as that measurement seems small. I maybe worrying for nothing but I'm sure you can imagine it's difficult not to worry xx

And he was bent right over so his feet were near his face. That's why I think it's a possibility of crl measurement xx
