How big is that, really?

Every flower in Zohra is drawn at the baby’s clinical length estimate for its week. Here is the whole story on one stage — drag through the weeks.

Long-stemmed rose, drawn at 51.2 centimetres
Week 40Long-stemmed rose · 51.2 cm (20.2 in) · head to heel
Week 50.2 cmWeek 4051.2 cm

Drag through the weeks. Every size here is the clinical estimate, not an artist’s guess.

Proportions are honest; absolute size is not — no web page knows how large your screen is. Weeks 5–19 are measured crown to rump and weeks 20–40 head to heel, so the jump at week 20 is the ruler changing, not a growth spurt. Weeks 1–4 state no size at all: pregnancy is dated from before conception, and there is nothing yet to measure.

The full table — the published fetal-length estimates the app draws from, in centimetres and inches.
