Measuring Tips

Determine your waist, hip, and thigh measurements with the help of our measuring tips. Then find your jean sizes in the charts below.

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.

Waist

Measure around the natural waist, keeping the tape measure taut.

Hips

Stand with your heels together and measure around the fullest part of your hips.

Inseam

Measure from crotch to floor- barefoot. Inseam is same length across all sizes. Choose between regular and exclusive inseams to find the right fit for you. Garment  inseams are in product descriptions.

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.
