Determining your bra size

Band Cup

Two components make up your bra size
band size (i.e. 32, 34, 36) and cup size (i.e. A, B, C).

Step 1: To determine your band size, wrap a measuring tape tightly around your rib cage. Then, add 5 inches to this measurement to get your band size. (ie: 27" rib cage + 5" = 32" band size).

Step 2: To find your cup size, measure loosely around the fullest part of your bust. Subtract your band size from this measurement. The difference determines your cup size (i.e. 0" difference = AA cup, 1" = A cup, and so on).


Difference 0 1 2 3"
Cup Size is AA A B C
Difference 4 5 6" -
Cup Size is D DD F(DDD) -
Difference 7 8 9" -
Cup Size is G H I -

Body types and fit


  • Trim figure with little or no additional flesh at cleavage or underarms.
  • Wear almost any type of bra from light and stretchy to fully constructed.

Small bust

  • Petite cleavage with no extra flesh at underarms or at bustline.
  • Shaping is important.
  • Look for lightly lined bras with contouring to help define your silhouette.
  • Underwire is also helpful

Firm full

  • You have a well-toned bustline.
  • You require more support than the average woman.
  • Look for bras with medium to firm support, underwire or natural cups.

Full Figure

  • You're less toned and have some flesh at cleavage and underarms.
  • Look for bras with wider, more rigid straps, side boning, a firm fabric construction in cups and underband.

Bra support levels

A combination of fabric and construction determines a bra's support. The amount of support you need depends on your age and toning.

light-support bras

  • Have the least amount of cup coverage made of stretchy fabrics.
  • Shoulder straps and back closures are narrow and delicate.

medium-support bras

  • Have a larger cup coverage.
  • Heavy stretch and non-stretch fabrics are often used.
  • Shoulder straps and back closures are slightly wider than on light-support bras.

firm-support bras

  • Provide the coverage needed to hold a full bust firmly in place.
  • Minimum or no-stretch fabrics are used.
  • Straps and back closure are quite wide.
  • Look for padded straps to help relieve pressure.


Bra fit dilemmas

Bra Fit Tip

For a proper fit, adjust straps so they give a firm but comfortable lift. The clasp should be on the first hook. Your bra should stay in place when you lift your arms, reach or twist. The tips below may help solve some of the problems you may be experiencing and help you get a better fit.

Below, we have listed common bra fit problems.
