Baby size at 20 weeks like a banana
Posted 21 Oct 2026
Around 20 weeks many mums enjoy the classic fruit comparison for bump chats. It is a gentle bit of pregnancy folklore, not a precise measure.

At roughly 20 weeks of pregnancy, the little one is often likened to a banana in those friendly fruit-size charts you see on fridge magnets and baby apps. It is a light-hearted way to picture how much they have grown since the early pea and grape stages.
These comparisons are pure entertainment. Every pregnancy unfolds at its own pace, and scans give a clearer picture than any fruit bowl ever could. Still, the banana image helps many parents share the milestone with family over a cup of tea.

You might notice the bump becoming more obvious around now, and feeling those first definite flutters can make the fruit analogy feel suddenly real. Keep enjoying the wonder without treating the chart as medical fact.
Old wives’ tales and lunar charts sit happily beside these size guides. Whether you are team banana or simply counting the weeks, the focus stays on looking after yourself and looking forward to meeting your baby.
If you have a mid-pregnancy scan coming up, that is the moment for proper measurements. Until then, smile at the banana comparison and carry on with your day.
