The calculator will provide you with both the band size and cup size, which you can use to find your perfect bra.

Taking Your Measurements

Accurate measurements are essential for finding the right bra size. Here's how to take them properly:

Band Size Measurement

Wrap a measuring tape around your ribcage, just under your bust, where a bra would sit
Make sure the tape is snug but not tight enough to dig into your skin
Record the measurement in inches

Bust Measurement

Wrap the measuring tape around the fullest part of your bust
Keep the tape level with your chest and parallel to the floor
Record the measurement in inches

For the most accurate results, take measurements when you're not wearing a bra or other clothing that could affect the fit.

Underbust Measurement

This measurement is optional but can help refine your cup size. Measure around the narrowest part of your bust, just below the band size measurement.

The Bra Sizing Formula

The calculator uses a standard bra sizing formula to determine your size:

Band Size: Round your band measurement to the nearest even whole number

Cup Size: Subtract the band size from the bust measurement, then round to the nearest whole number

For example, if your band size is 34" and your bust is 38", your cup size would be 4 (38 - 34 = 4).

The cup sizes correspond to letters as follows:

1 = A
2 = B
3 = C
4 = D
5 = DD
6 = E
7 = DD/E
8 = F
9 = DD/F
10 = G
11 = DD/G
12 = H
13 = DD/H
14 = I
15 = DD/I
16 = J
17 = DD/J
18 = K
19 = DD/K
20 = L
21 = DD/L
22 = M
23 = DD/M
24 = N
25 = DD/N
26 = O
27 = DD/O
28 = P
29 = DD/P
30 = Q
31 = DD/Q
32 = R
33 = DD/R
34 = S
35 = DD/S
36 = T
37 = DD/T
38 = U
39 = DD/U
40 = V
41 = DD/V
42 = W
43 = DD/W
44 = X
45 = DD/X
46 = Y
47 = DD/Y
48 = Z
49 = DD/Z
50 = AA

This formula provides a general guideline. Some brands may have slightly different sizing, so it's always a good idea to check the specific brand's size chart.

Worked Examples

Let's look at a couple of examples to see how the calculator works in practice.

Example 1: Small Bust

Measurements:

Band: 32"
Bust: 34"

Calculation:

Band size: 32" (rounds to 32)
Cup size: 34 - 32 = 2 (B cup)

Recommended size: 32B

Example 2: Large Bust

Measurements:

Band: 36"
Bust: 42"

Calculation:

Band size: 36" (rounds to 36)
Cup size: 42 - 36 = 6 (E cup)

Recommended size: 36E

Remember that these are general guidelines. Your actual fit may vary slightly depending on your body shape and the specific bra design.

Frequently Asked Questions

How accurate is this calculator?

This calculator provides a good estimate based on standard bra sizing formulas. However, since everyone's body shape is unique, you may need to adjust the size slightly for the best fit. Always try on different sizes to find what works best for you.

Why do my measurements give me a different size than what I usually wear?

Several factors can affect bra sizing, including the type of bra you wear (strapless, balconette, etc.), your body shape, and the specific brand's sizing. Some brands may have different cup sizes or band measurements than others.

How often should I measure myself for bras?

It's a good idea to measure yourself when you notice your bust has changed significantly, such as after gaining or losing weight, or when you're shopping for a new bra. As a general guideline, you might want to measure yourself every 6 months.

What if I can't find my exact size in stores?

If you can't find your exact size, try sizes one up or one down to see what works best. Some stores may offer custom sizing or have extended sizes available. Online retailers often have more size options available.
