Bra Sizing

Taking Measurements

To determine your bra size you have to take two measurements. When taking measurements, stand straight wearing your best-fitting bra (avoid padded or molded cup bras). Use a soft measuring tape.

Important: To get the most accurate size, we use the metrical system (millimeters/centimeters). If your measurements are in inches, please convert them to centimeters.

Measurements

  1. Underbust – with the soft measuring tape measure the girth of your chest just below the bust
  2. BCD – called the Bottom Cup Depth, measure the distance from the point of bust (the nipple) down to where the breast tissue meets the chest; take this measurement from both of your breasts

Size Calculator

The size from the calculator is for our bra pattern only. Do not use the calculator for patterns from other companies because they might use different sizing.
If you do not see the result after clicking the Calculate button, please see the FAQS page.

Please input inch values as 3.5 format

Do NOT input values in fractional format like: 3 3/8

About Sizing

Starting with year 2020, the way we determine the bra size has changed. We now use the Underbust and BCD (Bottom Cup Depth). Apart from this, nothing else has changed! The Maya bra has the same sizes. The download page is the same. Only the measurements and the calculation has changed.

To help you even more, instead of going through charts and loosing yourself among values of several tables we have implemented the Bra Size Calculator. The calculator does ALL the math and logic for you and outputs your bra size!

Afi Atelier uses external wire charts. When printing the charts, set the printer settings to “scale 100%” or “actual size“.  Every page in the file has a square with segment values. Check with your ruler that they match on your printed page. If they are not right, you’ll have to reprint and adjust printers scale settings.
