About this calculator
Measure snugly under the bust (underband) and around the fullest part of the bust. The band is the underband rounded to a whole size; the cup comes from the difference between the two measurements (1 inch ≈ A, 2 ≈ B, 3 ≈ C, 4 ≈ D …). EU band sizes are in centimetres in steps of 5. Fit varies by brand.
