How to Calculate Your Bra Size: A Clear Guide for Women
When it comes to finding the perfect bra, the first step is to determine your correct bra size. A properly fitted bra not only provides comfort but also enhances your appearance. However, many women struggle with getting the right size. The good news is that it's not as complicated as it may seem. In this article, we'll explore how to calculate your bra size accurately.
There are several methods to calculate your bra size, but the most common one involves measuring your band and bust sizes. It's important to note that your bra size can change over time, especially if you experience weight fluctuations, pregnancy, or nursing. Therefore, it's recommended to measure yourself regularly to ensure the perfect fit. In the following paragraphs, we'll discuss the steps to measure your band and bust sizes and how to use them to determine your bra size accurately.
Understanding Bra Sizes
When it comes to bras, finding the right size is crucial for both comfort and support. Bra sizes consist of two components: the band size and the cup size. The band size is the measurement of the area around the ribcage directly beneath the breasts. The cup size is the measurement of the bust.
Components of Bra Size
The band size is usually represented by a number, while the cup size is represented by a letter. For example, a 34C bra has a band size of 34 and a cup size of C. It is important to note that the cup size is relative to the band size. This means that a 34C bra has the same cup volume as a 32D or a 36B bra.
The band size is determined by measuring the circumference of the ribcage directly beneath the breasts. The measurement should be taken while wearing a non-padded bra, with the tape measure snug against the skin but not too tight. If the measurement is an odd number, round up to the nearest even number. This is because bra bands only come in even sizes.
The cup size is determined by subtracting the band size from the bust measurement. The difference between the two measurements corresponds to a letter in the alphabet. For example, a difference of 1 inch corresponds to an A cup, while a difference of 2 inches corresponds to a B cup, and so on.
Sister Sizes Explained
Sister sizes are alternate sizes that have the same cup volume but a different band size. For example, a 34C bra has the same cup volume as a 32D and a 36B bra. This means that if a person finds that their band size is not available in their preferred style, they can try a sister size instead.
It is important to note that while sister sizes have the same cup volume, the fit may not be exactly the same. This is because the band size affects the fit of the cups as well as the overall support of the bra. Therefore, it is recommended to try on both the sister size and the preferred size to determine the best fit.
By understanding the components of bra size and sister sizes, individuals can find a bra that fits comfortably and provides the necessary support.
Measuring Your Band Size
Proper Measuring Technique
To measure your band size accurately, you will need a soft tape measure and a mirror. Start by wearing a non-padded bra that fits you well. Stand in front of the mirror and wrap the tape measure around your ribcage, just beneath your bust. Make sure the tape measure is parallel to the ground and snug but not too tight. Take note of the measurement in inches.
Finding the Right Measurement
If the measurement you get is an even number, add four to it. If it's an odd number, add five to it. This will give you your band size. For example, if your measurement is 32 inches, add four to get 36. If your measurement is 33 inches, add five to get 38. Your band size is 36 or 38, respectively.
It's important to note that band sizes can vary between brands, so it's always a good idea to try on a few different sizes to find the one that fits you the best. A properly fitting bra should feel snug around your ribcage but not so tight that it's uncomfortable. It should also sit level across your back and not ride up.
By following these simple steps, you can determine your band size accurately and ensure that your bras fit you well.
Determining Your Cup Size
Measuring Bust Size
To determine your cup size, you first need to measure your bust size. To do this, wrap a measuring tape around the fullest part of your bust, making sure the tape is parallel to the ground and not too tight or too loose. Record this measurement in inches.
Calculating Cup Volume
Once you have your bust measurement, you can calculate your cup size by subtracting your band size from your bust measurement. Your band size is the measurement around your ribcage, just under your breasts. Use the measurement you got from the previous step, and round it up to the nearest whole number if it's not already a whole number.
To get your cup size, subtract your band size from your bust measurement. For example, if your bust measurement is 36 inches and your band size is 32 inches, your cup size is D. Use the table below to determine your cup size based on the difference between your bust and band measurements.
| Difference (in inches) | Cup Size |
|---|---|
| 0-1 | AA |
| 1-2 | A |
| 2-3 | B |
| 3-4 | C |
| 4-5 | D |
| 5-6 | DD |
| 6-7 | DDD/E |
| 7-8 | F |
| 8-9 | FF |
| 9-10 | G |
| 10-11 | GG |
| 11-12 | H |
| 12-13 | HH |
| 13-14 | I |
| 14-15 | II |
| 15-16 | J |
| 16-17 | JJ |
| 17-18 | K |
| 18-19 | KK |
| 19-20 | L |
| 20-21 | LL |
| 21-22 | M |
It's important to keep in mind that bra sizing can vary between brands and styles, so it's always a good idea to try on different sizes and styles to find the best fit for you.
Calculating Your Bra Size
When it comes to calculating your bra size, there are two main methods: using a bra size calculator or manually calculating your size.
Using a Bra Size Calculator
One of the easiest ways to calculate your bra size is by using a bra size calculator. There are several online calculators available that can help you determine your size based on your measurements. All you need to do is input your bust and underbust measurements, and the calculator will provide you with your recommended size.
Some popular bra size calculators include Calculator.net, Good Housekeeping, and Omni Calculator.
Manual Calculation Method
If you prefer to calculate your bra size manually, you can follow these steps:
Measure your underbust: using a soft measuring tape, measure around your ribcage just below your bust. Make sure the tape is snug but not too tight. Round up to the nearest whole number if needed.
Determine your band size: if your underbust measurement is an odd number, add 5 inches. If it's an even number, add 4 inches. This will give you your band size.
Measure your bust: measure around the fullest part of your bust, making sure the tape is parallel to the ground.
Determine your cup size: subtract your band size from your bust measurement. The difference will determine your cup size. For example, if the difference is 1 inch, your cup size is A; if it's 2 inches, your cup size is B; and so on.
It's important to note that bra sizing can vary between brands and styles, so it's always a good idea to try on different sizes and styles to find the best fit for you.
Trying on Bras
When trying on bras, it's important to assess both fit and comfort. Here are some tips to help you find the right bra:
Assessing Fit and Comfort
Band: The band should fit snugly around your ribcage, without feeling too tight or too loose. You should be able to fit two fingers between the band and your skin. If the band rides up, it's too loose. If it digs into your skin, it's too tight.
Cups: The cups should fully encapsulate your breasts without any spillage or gaping. If the cups are too small, your breasts may spill out. If the cups are too large, there may be gaping or wrinkles in the fabric.
Straps: The straps should be adjusted so that they're snug but not too tight. You should be able to fit two fingers between the strap and your shoulder. If the straps are digging into your skin, they're too tight. If they're slipping off your shoulders, they're too loose.
Underwire: The underwire should sit flat against your ribcage, without digging into your skin or poking out. If the underwire is digging into your skin, the cups may be too small. If the underwire is poking out, the bra may be too old or the wrong size.
Overall Comfort: You should feel comfortable and supported in your bra. If the bra is uncomfortable, itchy, or scratchy, it's probably not the right fit for you.
Adjusting for Shape Variations
Every woman's body is different, and there are a few shape variations that may affect bra fit. Here are some tips to help you adjust for these variations:
Asymmetry: If you have asymmetrical breasts, you may need to adjust the straps on one side to make the cups fit properly.
Fullness: If you have full breasts, you may need a bra with a higher center gore to prevent spillage.
Shallow Breasts: If you have shallow breasts, you may need a bra with a shallower cup to prevent gaping.
Wide-Set Breasts: If you have wide-set breasts, you may need a bra with wider-set cups to prevent the underwire from digging into your skin.
By following these tips, you can find a bra that fits well and feels comfortable. Remember to try on different styles and sizes to find the perfect fit for you.
Common Fitting Issues
Recognizing Poor Fit
It is essential to recognize the signs of a poorly fitting bra to avoid discomfort and other issues. Some common signs of a poor fit include:
- The bra band rides up on the back.
- The straps dig into the shoulders.
- The cups are too small or too big.
- The underwire digs into the skin.
- The bra feels uncomfortable or restrictive.
Solutions for Fitting Problems
If you are experiencing any of the above fitting issues, there are some solutions you can try:
- Bra band riding up: If the bra band is riding up on the back, it is a sign that the band size is too large. You may need to go down a band size to get a better fit.
- Straps digging in: If the straps are digging into your shoulders, it could be a sign that the band is too loose, and your bra is not providing enough support. Adjusting the straps can help, but you may also need to try a bra with a smaller band size.
- Cups too small or too big: If the cups are too small or too big, it can cause discomfort and affect the overall fit of the bra. Make sure to measure your bra size correctly and choose a bra with the right cup size.
- Underwire digging in: If the underwire is digging into your skin, it could be a sign that the cups are too small, and you need to try a larger size. Alternatively, you can try a bra without underwire for more comfort.
- Bra feels uncomfortable or restrictive: If the bra feels uncomfortable or restrictive, it could be a sign that the band size is too small. Try going up a band size to get a more comfortable fit.
By recognizing the signs of a poorly fitting bra and trying out some of the solutions above, you can find a bra that fits well and provides the necessary support and comfort.
Maintaining Bra Size Accuracy
Regular Measurement
To ensure that your bra size remains accurate, it is recommended to measure yourself every six months. This is because the body undergoes changes due to weight fluctuations, hormonal changes, and aging. Measuring yourself regularly will help you identify any changes in your bra size and ensure that you are wearing the correct size.
When measuring yourself, make sure to wear a non-padded bra or a fitted t-shirt. Use a measuring tape to measure around your back where your band sits and around the fullest part of your bust. Subtract the band measurement from the bust measurement to find your cup size. Use a bra size calculator for precision measurements.
Impact of Life Changes
Life changes such as pregnancy, breastfeeding, and menopause can also impact your bra size. During pregnancy, the breast tissue expands, and the rib cage widens to accommodate the growing fetus. This can result in an increase in bra size. After giving birth, the breast tissue may shrink, and the rib cage may return to its pre-pregnancy size.
Breastfeeding can also impact your bra size. The milk production process can cause the breast tissue to expand, resulting in an increase in bra size. After weaning, the breast tissue may shrink, and the bra size may decrease.
Menopause can also impact your bra size. As the body ages, the breast tissue may shrink, resulting in a decrease in bra size. Hormonal changes during menopause can also cause the breast tissue to become less dense, resulting in a change in bra size.
By measuring yourself regularly and taking into account any life changes, you can ensure that you are wearing the correct bra size and maintain your bra size accuracy.
