Measuring Tips

Here are some tips to help you order the correct size. If you don't have a measuring tape, use a piece of string and hold it alongside a ruler.

Things to Remember

Choose your maternity size based on your pre-pregnancy size. The maternity sizing allows room for a standard weight gain of 25-30 pounds.

Bust

Lift your arms up your sides and measure around your body, crossing over the fullest part of your chest.

Sleeves

With your arm bent and placed at your hip, measure from the back of your neck to your shoulder, elbow, and wrist.

How to measure without a ruler or tape measure?

If you don't have a ruler or tape measure handy, you can try to measure with a standard credit card, which has a width of 3 ⅜ inch or 8.56 cm and a height of 2 ⅛ inch or 5.4 cm.

If you do a lot of online apparel shopping, accurate body measurement using a tape measure is a must. The actual tape you choose doesn’t matter that much. This retractable one is very easy to use, and the fact it uses both CM and IN is extremely helpful.
