How to calculate your actual bra size

Measure Your Bust

  1. Bring the measuring tape around your torso where your bust is the fullest.
  2. Keep it straight, and level with the floor.
  3. Do not squeeze too tight or keep it too loose. Keep the tape nice and taught.
  4. Record your measurement in inches, rounding to the nearest half inch.

Measure Your Underbust

  1. Bring the measuring tape around your torso just underneath your bust.
  2. Keep it straight, and level with the floor.
  3. Do not squeeze too tight or keep it too loose. Keep the tape nice and taught.
  4. Record your measurement in inches, rounding to the nearest half inch.

Find Your Starting Points

  1. Using your Underbust measurement, add 0 inches to 1 inch to get the closest even number. Ex: If a woman’s Underbust is 29″, an odd number, she would add 1 inch to get 30.
  2. Next, subtract that number from your Bust measurement to get your cup size calculation. Ex: A woman’s Bust measurement is 33″. 33-30 = 3
  3. Using the English alphabet, find your cup size, using each letter for a number. 1 = A, 2 = B, etc. Ex: A woman’s cup size calculation is 3, so 1(A), 2(B), 3(C).

The thing to remember is that these starting points can help you pick a few sizes to start with - but it really comes down to how the bra fits. Each bra is different, so trying it on is the best way to be sure it fit properly. Follow these basic rules and you'll always feel comfortable:

  1. The band provides 90%of the bra’s support. Your bra should fit snugly around your torso and hug your body. Straps provide only 10% support
  2. The underwire should fit completely around your breasts.
  3. Cup size is only part of the equation. Get to know the shape of your bust
