Pregnancy Weight Gain Calculator

 
Weight gain is different for each woman and for each pregnancy. This calculator provides only a general guide to a woman's expected weight gain during her pregnancy.
It takes into account her normal height and weight prior to the pregnancy and suggests a range pregnancy weight gain.

Focus should not be so much on how much weight you gaining but how well you are eating!

How much weight should I gain?
The right answer is 'It varies.'
You should be gaining weight during your pregnancy, since you are carrying a little one inside you, and it is important for your health and the health of your baby. The exact amount of weight gain will somewhat depend on how much you weighed prior to conception. The pregnancy weight gain calculator will provide you with an estimate on weight gain, however, the chart below is useful as well.

On a Trimester Basis:
  • First trimester: 1 pound per month (4lb) in the first 12 weeks.
  • Second trimester: 1 pound per week for the next three months (12 - 14lb) in total.
  • Third trimester: around 1 pound per week (10lb) over the last 12 weeks.

But remember, these are average figures for large numbers of women so just because your weight gain pattern is different, it doesn't mean anything is wrong.
