How to Measure Bra Size
Step 1. Find Your Band size
Wear non-padded or unlined bra only.
Run the measuring tape all the way around your ribcage snugly, right under your bust and keep the tape level.
Refer to the below chart for your band size:
| Your Band Measurement (cm) | 64-68 | 69-73 | 74-78 | 79-83 | 84-88 | 89-93 | 94-98 | 99-103 | 104-108 | 109-113 |
| Your band size will be | 65 | 70 | 75 | 80 | 85 | 90 | 95 | 100 | 105 | 110 |
Refer to the below chart for your band size:
| Your Band Measurement (inches) | 25-26.6 | 27-28.6 | 29-30.6 | 31-32.6 | 33-34.6 | 36-36.6 | 37-38.6 | 39-40.6 | 41-42.6 | 43-44.6 |
| Your band size will be | 26 | 28 | 30 | 32 | 34 | 36 | 38 | 40 | 42 | 44 |
Step 2. Find Your Bust size
Run a loose measurement over the fullest part of your bust, under your shoulder blades and keep the tap level around your body.
Take a couple deep breaths and make sure the tape isn’t too tight.
Step 3. Determine Your Cup size
Subtract your band size from your bust measurement to find your cup size
Bust size – Band size = Cup size
| Centimetres | 10 = A | 12.5 = B | 15 = C | 17.5 = D | 20 = E | 22.5 = F | 25 = G | 27.5 = H | 30 = I | 32.5 = J |
Example:
Your bust measurement is 88cm, and your band size is 76 cm: 88 – 76 = 12. Using the chart above, you are a B cup , and you will want to shop for size 75B bras.
| Inches | 5.1 = A | 5.9 = B | 6.7 = C | 7.5 = D | 8.3= DD | 9.0 = F | 9.8= G | 10.6 = H | 11.4 = I | 12.2 = J |
