How much weight should you gain during pregnancy?

During pregnancy, you'll put on weight - not just the weight of the baby and placenta but also as your body's way of preparing for your baby and breastfeeding. The average amount of weight gain expected during a pregnancy will depend on whether you are currently over or underweight, and whether you are having a single or multiple birth.

This calculator will show you a personalised healthy expected weight gain range, and if you're pregnant and enter your current weight and how long you've been pregnant for, we'll also show you how you compare to a typical healthy pregnancy.
