Pregnancy Weight Gain Calculator

Our Pregnancy Weight Gain Calculator estimates healthy weight gain based on your pre-pregnancy weight, height (BMI), and current pregnancy stage. Enter your details, and it provides a recommended range aligned with medical guidelines.

You’ll need your pre-pregnancy weight, height, current weight, and the week of your pregnancy. Optional inputs like twin pregnancy or activity level can refine the results.

It’s based on guidelines from health organizations like the CDC or IOM, but it’s an estimate. Individual factors (e.g., metabolism, medical conditions) may affect actual weight gain, so consult your doctor.

Some versions allow you to input weights at different weeks to track progress against recommended ranges. Otherwise, you can manually compare weekly results.

Yes, if you indicate a multiple pregnancy (e.g., twins), it adjusts the recommended weight gain range based on guidelines for carrying more than one baby.
