What is a Cup Size?
A cup size refers to the measurement that defines the volume or size of a person’s breasts in relation to their band size. Cup sizes range from A to D and beyond, with each letter representing a different volume. The size of the cup is determined by the difference between your bust measurement (around the fullest part of your breasts) and your underbust measurement (around your ribcage). The larger the difference between these measurements, the larger the cup size will be.
For example:
- A 1-inch difference typically corresponds to an A cup.
- A 2-inch difference is typically a B cup, and so on.
How Cup Sizes Are Determined in the American System
The American cup size chart consists of two main components:
- Band Size: This is the number portion of your bra size, which corresponds to the circumference around your ribcage, just under your breasts.
- Cup Size: This is the letter portion of your bra size, which indicates how far your breasts extend from your body.
How to Measure for a Bra
Before diving into the American cup size chart, it’s important to know how to measure yourself correctly to ensure the best fit. Here’s how you can measure for both your band size and cup size:
Step 1: Measure Your Band Size
- Use a soft measuring tape: Wrap the measuring tape around your ribcage just under your bust, ensuring the tape is snug and level all the way around.
- Take the measurement in inches: Round to the nearest whole number. If you measure an even number, add 4 inches. If you measure an odd number, add 5 inches to get your band size.
For example:
- If you measure 30 inches, add 4 to get a band size of 34.
- If you measure 31 inches, add 5 to get a band size of 36.
Step 2: Measure Your Bust
- Measure the fullest part of your bust: Wrap the tape measure around your back and across the fullest part of your bust. Make sure the tape is level and comfortable, not too tight.
- Take the measurement: Round to the nearest whole number.
For example:
- If your bust measurement is 36 inches and your band size is 34, you would subtract 34 from 36 to get a difference of 2 inches, which typically corresponds to a B cup.
Step 3: Determine Your Cup Size
The difference between your bust measurement and band size determines your cup size. Use the following guide:
- 1-inch difference = A cup
- 2-inch difference = B cup
- 3-inch difference = C cup
- 4-inch difference = D cup
- 5-inch difference = DD (or E) cup, and so on.
It’s important to note that cup size increases by an inch for every increase in volume. For instance, a 34B will have a different cup size than a 36B, even though both are B cups. The 34 represents the band size, while the B represents the cup volume.

Cup Size Variations Across Different Brands
While the American cup size chart is standardized, it’s important to note that sizes can vary slightly between different bra brands. Factors like design, fit, and style may impact how the bra fits even if the size is the same. For example:
- A 34B from one brand may fit slightly differently than a 34B from another.
- Some brands also offer extended sizes, including larger cup sizes like H, I, and beyond, which may be available only in select lines or specialty stores.
When shopping for bras, it’s always best to try on different brands or purchase from stores that offer easy returns to ensure the perfect fit.
Tips for Getting the Perfect Fit
Finding the right cup size is crucial for comfort and support. Here are some tips to make sure you get the perfect fit:
1. Try Multiple Styles:
Different bra styles can fit differently. For instance, a push-up bra might fit differently than a sports bra. Try out different designs to find the one that suits you best.
2. Check the Band Fit:
The band should fit snugly but comfortably around your ribcage. If it’s too loose, the straps will bear more weight, which can lead to discomfort.
3. Adjust the Straps:
The straps should provide additional support but should not dig into your shoulders. Adjust the straps as needed for the right balance of support and comfort.
4. Comfort is Key:
Your bra should feel comfortable throughout the day. If you’re constantly adjusting it or feel any discomfort, it’s likely not the right size or style for you.
Conclusion
Understanding your cup size and band size is the first step in finding the perfect bra. The American cup size chart provides a comprehensive guide to help you make informed choices based on your measurements. While the chart can give you an estimate, it’s always a good idea to try on different bras to ensure the best fit, as sizes can vary by brand and style.
With the right bra size, you can enjoy all-day comfort and support, no matter your shape or size. Whether you’re shopping for a daily bra, something special, or sportswear, knowing your correct size will enhance both your confidence and comfort.
