20 week scan baby measurements

[Miss_BB]

I had mine at 20 weeks:

HC: 180mm
AC: 154mm
FL: 34.2mm

I was measuring above average, but within the normal ranges.

Wow, my baby is measuring a little smaller than all of yours! My notes don’t mention that the measurements are abnormal in any way, but I just did a little comparison check with all of your measurements.

I am small myself and my other half is only a foot taller than me so maybe it’s all proportionate!!

Here are my measurements at 20w + 2d:

Biparietal diameter (BPD): 47.0mm
Head Circumference (HC): 170mm
Abdominal Circumference (AC): 138.4mm
Femur Length (FL): 30.3mm
Est Fetal Weight: 289g (10 ounces)

Am I carrying the smallest baby?

This is quite a cool site, where you can see what the average measurements 'should be' at different stages...

You can also input your measurements and it estimates how many weeks you are, based on the measurements.

Bear in mind that the information provided cannot substitute the advice of a medical professional, so it's just for fun!

Mine were taken at 19+6 & are as follows:

Head Circumference (HC): 175mm
Abdominal Circumference (AC): 147.8mm
Femur Length (FL): 30.3mm

I'm not sure if the FL is 100% accurate, as baby was really awkwardly positioned, but the other two were measured clearly.
