We will walk you through everything you need to know about the bra size chart UK, helping you find your accurate size and say goodbye to ill-fitting bras for good.
This article will show you how to measure yourself correctly, understand what the numbers and letters mean, and use a detailed chart to pinpoint your perfect size.
Why Finding the Right Bra Size Matters
Wearing the correct bra size is about more than just comfort, it’s essential for your health and confidence. A well-fitting bra provides the necessary support for your breast tissue, which can prevent back pain, neck strain, and poor posture. It also helps your clothes fit better, creating a smoother silhouette and boosting your self-esteem.
Think about it: have you ever spent the day constantly adjusting your bra? That’s a clear sign it’s not the right fit. The right bra should feel like a second skin, offering support you barely notice.
How to Measure Your Bra Size at Home
You don’t need a professional to get an accurate measurement. With a soft measuring tape, you can easily find your Bra size at home. For the best results, measure yourself while wearing a non-padded, non-wired bra.
Here’s a simple two-step process:
1. Measure Your Band Size: Wrap the measuring tape snugly around your ribcage, directly underneath your breasts. Make sure the tape is level all the way around and parallel to the floor. Round the measurement to the nearest whole number. If the number is even, add 4 inches. If it’s odd, add 5 inches. it is your band size. For example, if you measure 30 inches, your band size is 34. If you measure 31 inches, your band size is 36.
2. Measure Your Bust Size: Now, wrap the tape around the fullest part of your bust, usually over the nipple. Keep the tape level, but don’t pull it too tight, it should just skim your body around this measurement to the nearest whole number.
3. Calculating Your Cup Size: Once you have your band and bust measurements, calculating your cup size is simple.
Bust Measurement (in inches) – Band Measurement (in inches) = Your Cup Size
Use the difference to find your cup size on the chart below:
| Difference in Inches | Cup Size |
|---|---|
| 0-inch difference | AA Cup |
| 1-inch difference | A Cup |
| 2-inch difference | B Cup |
| 3-inch difference | C Cup |
| 4-inch difference | D Cup |
| 5-inch difference | DD Cup |
| 6-inch difference | E Cup |
| 7-inch difference | F Cup |
| 8-inch difference | FF Cup |
Real-life example: If your band measurement gave you a band size of 34 and your bust measurement is 37 inches, the difference is 3 inches. That means your bra size is 34C.

Understanding Sister Sizing
What if a bra in your measured size doesn’t feel quite right? This is where sister sizing comes in. Sister sizes are alternative sizes where the cup volume stays the same, even though the band and cup letter change.
The rule is simple:
- If you go down a band size, go up one cup size. (e.g., a 34C has the same cup volume as a 32D).
- If you go up a band size, go down one cup size. (e.g., a 34C has the same cup volume as a 36B).
This is incredibly useful when a specific style runs tight or loose in the band. If the band on a 34C feels too snug but the cups fit perfectly, try a 36B.
Common Signs of a Poorly Fitting Bra
Are you unsure if your current bra is the right size? Here are five common signs to look out for:
- The Band Rides Up: Your bra band should sit horizontally across your back. If it’s riding up, the band is too loose and not providing enough support.
- Spillage or Gapping: If your breasts are spilling out of the top or sides of the cups, the cup size is too small. If there are gaps between your breast and the cup, it’s too big.
- Straps Digging In: Shoulder straps should only provide about 10% of the support. If they are digging into your shoulders, your band is likely too loose and not doing its job.
- The Underwire Pokes You: The underwire should sit flat against your ribcage and completely encase your breast tissue. If it’s digging into your breasts or armpits, the fit is incorrect.
- The Center Panel Lifts Away: The part of the bra between the cups (the gore) should lie flat against your sternum. If it’s lifting away, your cup size is too small.
UK vs. EU vs. US Bra Sizing
Bra sizing can be confusing, especially when shopping from international brands. While the UK uses a DD, E, F, FF cup progression, the US often uses DD/E, DDD/F, G. European sizing (EU) is different altogether, using centimeters for band sizes. Always check a brand’s specific size conversion chart before you buy.
Tips for Trying on a New Bra
When you try on a new bra, make sure it fits perfectly on the loosest hook. it allows you to tighten it as the band naturally stretches over time. Bend over and gently scoop your breast tissue into the cups to ensure everything is sitting correctly. Finally, put on a close fitting t-shirt over the bra to check the silhouette. It should be smooth and supportive.
When Should You Re-measure?
Your body changes over time, and so does your bra size. It’s a good idea to remeasure yourself every 6-12 months. Major life events can also impact your size, so be sure to check your fit if you experience:
- Weight gain or loss
- Pregnancy or breastfeeding
- Hormonal changes or menopause
