To begin, enter your height, pre-pregnancy weight and current week. The tool will then provide a general estimate of weight-gain ranges based on the information you enter.
Although pre-pregnancy body mass index is commonly used when discussing pregnancy weight gain, individual needs can vary. Therefore, calculator results should be treated as general guidance rather than a personal medical recommendation.
Understanding Pregnancy Weight Gain
During pregnancy, weight can change at different rates. Factors such as starting weight, pregnancy stage, nutrition, activity, fluid changes and individual health needs can all affect the amount gained over time.
Because every pregnancy is different, your healthcare professional may recommend a range that differs from a general calculator estimate based on your medical history and pregnancy.
