How do You Measure Your Chest Size

If you want to buy a fitted suit or shirt, you'll need to know your chest size. To find your chest size, all you need is a measuring tape and a pencil to write the number down.

Choose a flexible measuring tape, usually a short fiberglass tape measure, not a steel measuring tape. This fiberglass tape measure is easy to wrap around your chest, and accurately measuring curves. If you don't have one tape, you can instead wrap a string around your chest, then measure that with a ruler.

The professional waist tape measure or BMI measuring tape is the perfect choice for your chest measurement. because simply pulling the measuring tape will keep the measurement locked in place, and push-button retraction features of them  ensure snug measurement,  it is easy to measure by yourself.

When taking these measurements, circle your chest, the tape is level and neither too tight nor too loose. Also measure yourself on your bare skin, not over clothes. So remove your shirt, and take off your regular bra, grab a thin tank or sports bra. Any extra fabric will add a few centimeters to your measurement.

If you just have a simple fiberglass tape, It can be hard to take an accurate chest measurement by yourself, so you may need a friend to help you.  If you have a professional waist tape measure or BMI measuring tape, everything becomes easy.

Wrap the tape measure around your chest. Position it so that the tape is horizontal to the ground, and falls just under your armpits. Bring it around your back so that the ends come together in front, across the widest part of your breasts.

If you ae using a professional waist tape measure or a BMI tape, then you can

  1. Lock the rod (also called pin) at the end of the tape forming a circular tape wrapping the body part.
  2. Press the button in the center,and let the tape retract to fit snuggly on your body.




Measure the circumference of your upper chest first, that's the area right above your breasts. Wrap the measuring tape around your back, shimmying the tape up and under your armpits so it's across your breast bone and creates a straight, even line from armpit to armpit. Take the measurement and use the same technique each time you measure for consistent readings.


Lower the measuring tape to take your lower chest measurement. This is the measurement from right across your nipples -- the one that your bra fitter uses. Exercise and weight loss can affect the size and shape of your breasts, so it's an important measurement to take. Take the measurement over the nipple and write it down as the lower chest size.
