Bra Size Calculator

By using a bra size calculator, you will be able to get the best fitting bra possible. Unless the bra fits properly, discomfort will be felt. A tight fitting bra will also leave reddish marks. These calculators (which are free on the Web) will help you find the right size.

How to Use the Calculator

Look for one using a search engine. When you get to the site, you will see the following fields: below, bust and above. Enter your figures. Click “calculate”.

The correct size will appear. Usually the answer will be given in a variety of sizes (American, UK, European, Japanese, French etc). The measurements of bra size calculators can be whole numbers or in decimals.

How to Measure Bra Size

You should wear an ordinary underwired bra. Do not wear padded or push up bras. Stand up, with the back and shoulders straight. Do not hold your breath or expand the chest. Stay relaxed.

Step 1: Measure the Band Size

Get a soft tape measure. Place it snugly all around the rib cage. It should be just under your breasts. Be sure the tape is set all the way around. Measure it in centimeters or inches. You can enter this into the bra size calculator.

Step 2: Measure the Bust Size

Place the tape at the fullest section of the bust. This will be just above the nipples. Ensure the tape is straight around your body. The measurement can also be in inches or centimeters.

Step 3: Measure the Above Bust Size

Take your measurement at the rib cage above the breasts and under the arms. Be certain the tape measure is level. Note: this measurement is considered optional, but for the sake of accuracy it is better to make this measurement too.

Tips

The bra size is correct if there is no digging or poking sensations. Walk around. It should feel comfortable. The bra is too big if the cup is baggy or getting wrinkled. If there is puddling or falling out, the cup is not large enough. You need to get a bigger cup size. Also, the straps should not be hard.

Using a bra size calculator will help you get the right size. Women who wear the wrong size often experience discomfort, but by utilizing the tool, you can steer clear of this problem.
