We created this bra size calculator to help women determine correct bra size on m&s, victoria secret, adidas, debenhams, aerie, bravissimo.
For example, a common conversion might look like this:
- Measure the band size: 32 inches
- Measure the bust size: 36 inches
- Calculate the difference: 36 – 32 = 4 inches
- Convert the difference to a cup size: 4 inches = D cup
In this case, the resulting bra size would be 32D.
The calculator typically uses two primary measurements: the band size (the circumference around the ribcage just under the breasts) and the cup size (the difference between the band size and the fullest part of the bust).
Bra Size Calculator
| Underbust (cm) | Overbust (cm) | Calculation | European Size | US/UK Size |
|---|---|---|---|---|
| 70 | 85 | 85 – 70 = 15 cm (E cup) | 70E | 32DD |
| 75 | 90 | 90 – 75 = 15 cm (E cup) | 75E | 34DD |
| 80 | 93 | 93 – 80 = 13 cm (D cup) | 80D | 36D |
| 85 | 100 | 100 – 85 = 15 cm (E cup) | 85E | 38DD |
| 90 | 108 | 108 – 90 = 18 cm (F cup) | 90F | 40DDD/F |
Conversion Equation: US/UK Band Size = European Band Size / 2.54 – 26 (rounded to nearest even number) Cup Size: Every 2 cm difference = 1 cup size (A, B, C, D, etc.)
Bra Size Conversion Formula
The advanced formula for bra size conversion involves several steps:
- Underbust measurement: Measure around the ribcage, just under the breasts.
- Overbust measurement: Measure around the fullest part of the bust.
- Calculate band size: Round the underbust measurement to the nearest even number.
- Determine cup size: Subtract the band size from the overbust measurement.
- Convert difference to cup size: Use a standardized chart to convert the difference to a letter.
For example:
- Underbust: 31 inches
- Overbust: 37 inches
- Band size: 32 inches (rounded up from 31)
- Difference: 37 – 32 = 5 inches
- Cup size: 5 inches = DD (or E in some systems)
The calculated bra size would be 32DD or 32E.
How do I calculate my bra size?
To calculate your bra size:
- Measure your band size:
- Wrap a measuring tape snugly around your ribcage, just under your breasts.
- Round to the nearest whole number.
- If it’s odd, add 1 inch to get an even number.
- Measure your bust size:
- Wrap the tape around the fullest part of your bust.
- Keep the tape level and snug, but not tight.
- Calculate the cup size:
- Subtract your band size from your bust measurement.
- Each inch of difference represents a cup size (1″ = A, 2″ = B, 3″ = C, etc.).
- Combine the results:
- Your band size + your cup size = your bra size (e.g., 34C).
Remember that this is a starting point, and trying on bras is crucial for finding the perfect fit.

How to measure bra size in Europe?
In Europe, bra sizing follows a slightly different system:
- Band size: Measure your underbust in centimeters. Round to the nearest 5 cm (e.g., 73 cm becomes 75 cm).
- Cup size: Measure your overbust in centimeters. Subtract the band size from this measurement.
- Determine cup: Each 2 cm difference represents a cup size (0-2 cm = A, 2-4 cm = B, etc.).
For example:
- Underbust: 73 cm (rounded to 75 cm)
- Overbust: 89 cm
- Difference: 89 – 75 = 14 cm
- Cup size: 14 cm = G cup (in most European systems)
The resulting European bra size would be 75G.
Is a 36B bra size big or small?
A 36B bra size is generally considered to be average in terms of cup size. The “36” refers to the band size, which is also in the medium range for many women.
It’s important to note that perceptions of “big” or “small” can vary greatly depending on individual body proportions and personal preferences.
Is 32E bra size big?
A 32E bra size is often considered to be on the larger side in terms of cup size, especially in proportion to the band size.
The “32” indicates a relatively small band size, while the “E” cup suggests a significant difference between the underbust and overbust measurements.
80 cm bra size means
An 80 cm bra size typically refers to the band size in the European sizing system. This measurement corresponds roughly to a 36 band size in the US/UK system.
To determine the full bra size, you would need to know the cup size as well. For example, an 80B in European sizing would be approximately equivalent to a 36B in US/UK sizing.
