Dear ladies, let's gather up and measure the average breast size. All you need to do is enter your measurements into the above form.

I really hope that you'll be happy with the average result! ;)

Approximately 70% of all women don't know their right breast and bra sizes. By not knowing true measurements, you can get into trouble while buying your clothes. Wearing the bra that is not the right size can also cause various health problems, so it's very important to get serious about this.

Also your breast size vary over time, mostly during and after pregnancy, but also if you experience some weight loss or gain, therefore you should check your breast/bra size a few times annually.

What you need to do:

• Get someone else to take your measurements - you will be more relaxed and the sizes will be accurate
• Stand up straight while breathing normal
• Don't measure over the clothes
• Use a tailor's measuring tape if possible

Measuring the breast size
(bust circumference size)
1. Measure around the chest just under the breast at a constant height with the tailor's measuring tape. Add 5 inches to that size. This dimension is your bra/band size (If the bra size works out to an ODD number go up one inch to the next EVEN number.) This should equal the circumference around the chest, directly above the breasts/under the arms.
2. Measure around the chest at the height of the fullest part of the breast. The measuring tape should be held horizontally on your back, and your arms should be down. Make a note of that measurement (only used for comparison) and compare it to the Bra Size from step 1.
