How to Determine Bra Size
Determining the right bra size is essential for comfort, support, and overall well-being. Wearing a bra that fits correctly can make a significant difference in how you feel throughout the day. This guide will walk you through the steps to determine your bra size, including measuring techniques, understanding size charts, and tips for finding the perfect fit.
Understanding Bra Sizes
Bra sizes are typically expressed in a combination of a number and a letter, such as 34B or 36DD. The number represents the band size, which is the measurement around your ribcage just under your bust, while the letter represents the cup size, which indicates the volume of your breasts.
Components of Bra Size
- Band Size: The number in your bra size. It corresponds to the measurement around your ribcage.
- Cup Size: The letter in your bra size. It indicates the volume of your breasts relative to your band size.
- Ribcage Measurement: 30 inches
- Band Size: 30 + 4 = 34
- Band Size: 30 + 5 = 35 (round up to 36)
- Bust Measurement: 37 inches
- Underwire vs. Wireless: Underwire bras provide more support but can be uncomfortable for some. Wireless bras are generally more comfortable but may not offer the same level of support.
- Different Cup Shapes: Full coverage, demi-cup, and balconette bras can fit differently depending on your breast shape and size.
- The band should be snug but not tight. You should be able to fit two fingers underneath it.
- If the band rides up your back, it’s too loose.
- The cups should fully encase your breasts without any overflow (spillage) or gaping.
- If you see any spillage, try a larger cup size; if there’s gaping, try a smaller cup size.
- Straps should be adjusted to sit comfortably on your shoulders without digging in or slipping off.
- A common adjustment is to ensure that the straps can hold the weight of the breasts without the band doing all the work.
- Raise your arms, bend over, and do a little dance to see how the bra moves with you. A good bra should stay in place and provide support during movement.
- European Sizes: Often labeled with a number and a letter (e.g., 75B).
- UK Sizes: May differ from US sizes (e.g., a 34B in the US may be a 34C in the UK).
How to Measure Your Bra Size
To find your correct bra size, you’ll need to perform a few simple measurements. It’s best to do this while wearing a non-padded bra to ensure accuracy.
Step 1: Measure Your Band Size
1. Wear a Fitted Bra: Start with a well-fitting, non-padded bra.
2. Find Your Ribcage Measurement: Use a soft measuring tape to measure around your ribcage just under your bust. Make sure the tape is parallel to the ground and snug but not tight.
3. Round Up: If the measurement is an even number, add 4 inches. If it’s an odd number, add 5 inches. This will give you your band size.
Example:
Step 2: Measure Your Bust Size
1. Measure at the Fullest Part: Wrap the measuring tape around the fullest part of your bust. Ensure the tape is straight across your back and not too tight.
2. Record the Measurement: Take note of this measurement.
Example:
Step 3: Calculate Your Cup Size
To find your cup size, subtract your band size from your bust measurement.
1. Bust Measurement: 37 inches
2. Band Size: 34 inches
3. Difference: 37 – 34 = 3 inches
Cup Size Chart
| Difference (inches) | Cup Size |
|---|---|
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | DD/E |
| 6 | DDD/F |
| 7 | G |
| 8 | H |
In our example, a 3-inch difference indicates a cup size of C. Therefore, the bra size would be 34C.
Tips for Finding the Perfect Fit
Finding the perfect bra is about more than just numbers. Here are some tips to consider when trying on bras:
1. Try Different Styles
2. Check the Band Fit
3. Examine the Cup Fit
4. Adjust the Straps
5. Move Around
Understanding Bra Size Variations
Sister Sizes
Sister sizes are alternative sizes that have the same cup volume but different band sizes. For example, if you wear a 34C, your sister sizes would be 32D and 36B. If you find that your band is too tight or loose, you can try a sister size while adjusting the cup size accordingly.
Size Conversion Across Brands
Different brands may have slight variations in sizing. It’s essential to try on bras from various brands to see which fits you best. Here are some general tips:
Common Bra Size Issues
1. Bra Digging into Skin
If your bra digs into your skin, it may be too tight. Try going up a band size or adjusting the straps.
2. Constant Adjustments
If you find yourself constantly adjusting your bra throughout the day, it might be too loose. Consider a smaller band size.
3. Spillage
If your breasts spill over the top of the cups, the cup size is too small. Try going up a cup size.
4. Gaping Cups
If there is extra fabric in the cups, the cup size is too large. Try a smaller cup size.
FAQ
