The Complete Size & Fit Guide for Baby Bodysuits
We know how important it is to find the perfect personalised baby bodysuit for your little treasure. In this guide, we'll share everything you need to choose the right size and fit for a baby bodysuit, so your little one stays comfy and looks lovely.

Understanding baby bodysuit sizes
Baby bodysuits come in a range of sizes, usually shown as an age in months. But it's worth remembering that every baby is unique and grows at their own pace. At Babanono, we recommend going by your baby's height and weight rather than their age. A '0–3 months' bodysuit, for example, is generally designed for babies weighing between 4 and 6 kg.
Always check the size chart on our website for an accurate fit.
| Bodysuit size | Approximate age | Weight | Length |
| Prem | Premature | Up to 2.5 kg | Up to 45 cm |
| 0–1 month | 0–1 month | 2.5 – 3.5 kg | 45 – 50 cm |
| 0–3 months | 0–3 months | 4 – 6 kg | 50 – 60 cm |
| 3–6 months | 3–6 months | 6 – 8 kg | 60 – 67 cm |
| 6–9 months | 6–9 months | 8 – 9.5 kg | 67 – 72 cm |
| 9–12 months | 9–12 months | 9.5 – 11 kg | 72 – 78 cm |
| 12–18 months | 12–18 months | 11 – 12.5 kg | 78 – 83 cm |
| 18–24 months | 18–24 months | 12.5 – 13.5 kg | 83 – 90 cm |
This chart is a great starting point for choosing the right size. Even so, it's always best to measure your baby and compare their measurements with the chart to be sure of a perfect fit — especially when ordering personalised bodysuits. It's also worth remembering that babies grow at different rates, so a size that suits one baby may not suit another of the same age.
Choosing the right fit
The fit of a bodysuit matters just as much as the size. As with any personalised baby clothing, bodysuits come in a variety of styles — long- or short-sleeved, and with or without feet. For the colder months, long-sleeved bodysuits with feet keep your baby snug from head to toe. In summer, opt for short sleeves or sleeveless styles for better airflow. At Babanono, we offer a range of styles to suit every need.
The importance of material
The fabric of a bodysuit is key to your baby's comfort. Materials like pure cotton, bamboo and breathable cotton blends are ideal for babies' sensitive skin. They wick away moisture, keeping your baby dry and comfortable. Our personalised Babanono bodysuits are made with high-quality fabrics to keep your little one comfy all day long.
Personalisation tips
Personalisation is what makes our Babanono bodysuits so special — you'll find our different bodysuits in our baby gift sets. When personalising, keep the colour and design of the bodysuit in mind. Text or a design that's too large can be uncomfortable for baby. Go for simple, gentle designs that add a personal touch without compromising on comfort.
At Babanono, we're dedicated to creating high-quality bodysuits that are comfortable, stylish and perfectly suited to your baby. Giving a personalised baby gift to friends is always a lovely idea. Follow this guide to choose the best size, fit and fabric, and create an unforgettable keepsake with our personalisation options.
