Signature explorer

How big is baby this week? Ask the market.

Apps compare your baby to fruit nobody here buys. This explorer speaks Mauritian: a litchi at week 10, a mangue Jose at 17, a banane at the halfway mark, an ananas Victoria at 25, and a full giraumon when you reach the due week. Slide through the weeks, with average lengths and weights alongside.

Week 20

Second trimester

About the size of

a banana (banann)

Average length
about 25.6 cm
Average weight
about 300 g

Halfway. From here, length is measured head to heel, which is why the number jumps.

Weeks 13-27: The growth trimester: energy often returns, the bump shows, movements begin, and the anomaly scan happens. Lengths are crown to rump until week 20 and head to heel after (that is why week 20 jumps). All figures are published averages; healthy babies vary widely, and your own scans are the measurements that matter.
