The Bra Size 75B

Band size 75 sits snugly under the bust to anchor the bra and provide core support.

Cup size B indicates relative breast volume to the band, ensuring proper coverage and shape.

Sister Sizes

The sister sizes appropriate for 75B bras are 70C or 80A, depending on whether you prefer a snugger or looser band.

What Are Sister Sizes?

Sister sizes are alternative bra sizes that have the same cup volume but different band measurements. By adjusting one band size up and one cup size down (or vice versa), you can find a fit that offers the same support and shape if your usual size feels too tight or too loose.

Frequently Asked Questions

To measure your bra size at home, use a soft measuring tape. First, measure your band size by wrapping the tape around your ribcage, just under your bust, keeping it snug.

For the cup size, measure around the fullest part of your bust. Subtract the band size from the bust size; each inch difference represents a cup size (e.g., 1 inch = A, 2 inches = B, and so on).

To find your correct bra size, you need two measurements:
  • Band Size: Measure around your ribcage, just under your bust. Make sure the tape is snug but not too tight.
  • Bust Size: Measure around the fullest part of your bust, making sure the tape is parallel to the floor and not too loose.
Once you input these measurements into the calculator, it will generate your bra size.

After measuring your bust and band size, subtract the band size from your bust measurement. The difference determines your cup size:

1 inch = A cup, 2 inches = B cup, 3 inches = C cup, and so on.

For example, if your bust is 36 inches and your band is 34 inches, the difference is 2 inches, meaning a B cup.

Yes! Our calculator allows you to switch between inches and centimeters.

You can input your measurements in either unit, and the calculator will automatically convert them.

Our calculator is designed to be as accurate as possible by using standard sizing charts from various popular brands.

However, your comfort and preference may vary depending on the style and fit of each brand. Use the results as a starting point and try different sizes if needed.

Our bra size calculator supports a wide range of sizes, including smaller and plus sizes.

We include band sizes from 27 in to 56 in or 60 cm to 120 cm and cup sizes from A to Z, covering most standard bra sizing systems.

If your size is in between, we recommend trying both sizes and choosing the one that feels more comfortable.

You can also look for bras labeled as "sister sizes" for a more tailored fit.

Our calculator works for most bra types, including t-shirt bras, sports bras, balconette bras, and more.

However, specialized bras like maternity or post-surgical bras may require additional considerations.

To ensure accurate results, the bust size dropdown adjusts based on your selected band size.

This is because bust size is relative to band size, and this dynamic dropdown helps you pick the most appropriate range for your bust.

Currently, bra size calculator does not store personal data for privacy reasons.

However, you can take a screenshot of your results or write them down for future reference.

The biggest bra size varies by manufacturer, but some brands offer cup sizes up to an O or P. Band sizes can go up to 58 or larger. Specialized lingerie stores and custom bra makers may accommodate larger sizes.

Bra sizes may vary between brands due to differences in their sizing systems. Our calculator provides brand-specific recommendations, helping you find the closest match for each brand.

Bra sizing can vary slightly between brands due to different sizing systems and fit models. While most brands use similar band and cup measurements, some may run smaller or larger. It's recommended to try on bras from different brands or refer to size charts specific to each brand.

A good-fitting bra should:
  • Be snug around the band without digging into your skin.
  • Have cups that fully contain your breasts without gaps or spillage.
  • Have straps that sit comfortably on your shoulders without slipping off or digging in.
If you notice discomfort, you may need to try a different size.

Signs include the band riding up your back, straps digging into your shoulders, gaping or spillage from the cups, and discomfort or pain during wear. These indicate that you might need a different size.

Wearing the wrong bra size can lead to discomfort, back and shoulder pain, skin irritation, and poor posture. Ill-fitting bras, especially too tight or too loose, can also affect breast shape and support.

It’s normal for your bra size to change due to factors such as weight changes, pregnancy, or aging. We recommend measuring your bra size every six months to ensure a proper fit.

To support sagging breasts, look for bras with firm underwire, full coverage cups, and wide straps. Minimizer bras, full-cup bras, and bras with side panels can provide lift and structure, giving a firmer appearance.

A minimizer bra is designed to reduce the appearance of the bust by distributing breast tissue more evenly. It’s ideal for women with larger breasts who want a smoother look under clothing or wish to reduce projection.

A push-up bra enhances cleavage by lifting the breasts with padding, typically pushing them together. A balconette bra, on the other hand, offers a more natural lift and wide-set shape, revealing the upper part of the bust and providing a rounded look without significant padding.

A water bra contains liquid or gel inserts in the cups to enhance cleavage and provide a fuller appearance. It’s often used by those looking for extra volume or a more rounded shape.

A T-shirt bra is seamless and designed to be invisible under tight clothing. It provides smooth, full coverage. A plunge bra, however, has a deep V-shaped neckline, making it ideal for low-cut tops while enhancing cleavage.

You should replace your bra every 6-12 months, depending on wear and care. Signs it’s time for a replacement include stretched-out bands, misshapen cups, or loss of support. Wearing a rotation of bras helps them last longer.

Hand washing in cool water with mild detergent is best to maintain a bra’s shape. If using a washing machine, place bras in a mesh bag and use a gentle cycle. Always air dry bras to prevent elastic damage.

You can get professionally fitted for a bra at lingerie stores, department stores with lingerie sections, or specialty bra shops. Some well-known stores, like Marks & SPencers, Victoria’s Secret, etc. offer free bra fitting services.

A sports bra is designed for high-impact activities and offers more compression and support to minimize breast movement. It usually has wider straps, a racerback design, and moisture-wicking fabric. A regular bra focuses more on shaping and comfort for everyday wear.

No, there is no scientific evidence that links not wearing a bra to sagging breasts. Sagging is influenced by factors such as genetics, age, and weight fluctuations rather than bra-wearing habits.

Bra sizing systems differ by country due to variations in measurement standards and conventions. For example, US, UK, and European sizes use different scales, which can result in different labels for the same bra measurements.
