Bra Sizes Explained: 34 75 bra size big or small？

Bra Sizes Explained:  34 75 bra size big or small？

In order to know your bra size，it can greatly enhance comfort, support, appearance — especially when shopping online (like Singapore, Malaysia and other places). In this blog, it’ll break down what bra sizes like 34, 36, 75, and 80 actually mean, how to measure yourself the right way, and how cup sizes work—so you can shop more confidence. We’ll also answer common questions like “Is a 75B the same as a 34B?” “What’s the equivalent of a 34C bra size?” and more.

Understanding the Basics of Bra Sizing

When you see a bra size like 34B, 36C, 75A or 80D, it is made up of two parts: a number (band size) and a letter (cup size).

• The number (cup size) refers to the circumference of the rib‐cage (under the bust) — the part of the bra that wraps around you.

   

• The letter (cup size) refers not directly to breast volume but to the difference between the bust measurement (fullest part of the chest) and the bra size measurement.

This means that band + cup together determine the fit and support. Furthermore, because of “sister sizes”, the same cup volume may appear in different number-letter combinations (e.g., 34B might carry the same cup volume as 32C or 36A).

How to Measure Your Bra Size at Home

Getting accurate measurements is key to picking the right size. Here’s how:

1. Measure your band (under-bust): Using a soft measuring tape, wrap it around your torso just under the bust where the bra band would sit. Make sure the tape is level and snug.

    

2. Measure your bust (fullest part): Standing upright, measure around the fullest part of your bust (typically across the nipples) with the tape level and not too tight.

    

3. Calculate your size:

• The band size is often the under-bust measurement rounded to a standard band number.

   

• The difference between the bust measurement and the band measurement gives the cup size. For example: bust 37 inch, band 34 inch → difference 3 inch → a ‘C’ cup in many sizing systems.

Once you know your band size, you can check how it fits with styles like the Veimia Everyday Lift Bra.

What Do Sizes 34, 36, 75 and 80 Mean?

It can be confusing because different regions use different systems (inches vs centimetres; US/UK vs Europe/Asia).

• Band size 34 & 36: These are commonly used in inch‐based systems (US/UK). For example, a band size of 34 means the rib cage around the underbust is approx. 34 inches. The next standard up is 36, etc.

   

• Band size 75 & 80: These often correspond to measurements in centimetres (EU/Asia sizing). For example, “75” might represent approx. 75 cm under-bust. Many charts list 75A, 75B, 80C, etc. For instance, a conversion chart shows 75A under-bust 73-77 cm etc.

   

• Conversion between inch and cm systems: To choose correctly when shopping internationally (especially in Singapore/Malaysia where Asian/EU size labels may appear), you’ll need to check conversion tables. For example, a 34 band size may roughly correspond to a 75 or 80 in a different system depending on brand.

For 34C / 75C fits, full-coverage types such as Veimia Minimizer Bra give smooth contouring under blouses.

Common Specific Sizes & Their Equivalents

Let’s address some very common questions:

• Is 75B the same as 34B?

The short answer: maybe, but not always. In many conversion tables, a 75B bra size (under-bust around 73-77 cm) corresponds roughly to a 34B bra size in inch‐based systems. For example, one chart lists 75A as corresponding to 34A in some systems. But because brand cut and “true cup” may vary, you still need to check actual fit.

• What is a 34C bra size equivalent to?

A 34C means band 34 (inch system) and cup difference of roughly +3 inches (for typical US/UK). Equivalent sizes in sister sizing could be 32D or 36B (same cup volume, different band).

• Are 34E and 34DD the same?

Depending on the system (US vs UK vs Europe), 34E bra size may equal 34DD in some contexts. Cup letters differ by region. For example UK uses DD, E, F; US uses D, DD, DDD/E etc. So 34E (UK) often equals 34DDD/E (US). One conversion chart shows E in EU ≈ DD in UK/US.

• How big is a 34-inch chest?

If your band is 34 inches (≈86 cm) around the under-bust, that is considered moderate band size (neither extremely small nor large). For many women this falls into the medium band category. The bust measurement would depend on cup size.

• Is size 36 medium or large?

A 36 band size (inch system) is one step above 34; in many sizing charts this could be considered still within the “medium” band range, though how it’s classified may depend on region/brand. The cup size also affects perceived “size”.

Why Fit Still Varies Even with the “Correct” Size

Knowing your numeric size is just the starting point. Several factors affect how a bra actually fits:

• Brand and style differences: Each lingerie brand may cut their bands tighter or looser; some styles (push-up, plunge, full-cup) will fit differently.

   

• Cup volume is relative: A D cup on a 34 band is not the same volume as a D cup on a 38 band.

   

• Sister sizes can help: If a 34C is too tight in the band but cups fit, you might try 36B (same cup volume but larger band).

   

• Body and lifestyle factors: Changes in weight, health, pregnancy, even posture can affect fit.

   

• Measurement errors: If you measured incorrectly (tape too tight/loose, wrong position), then the size might be off.

If your 36C feels loose, the adjustable side-wing design in Veimia Perfect Hold Anti-sagging Bra helps you fine-tune the fit.

Summary & Actionable Next Steps

Quick check list:

• Measure yourself (under-bust and bust) → Determine band size → Determine cup size.

   

• Use a conversion chart if you’re switching sizing systems (inch ↔ cm).

   

• Try on the bra, check fit: band should sit firm on the loosest hook; cups should fully contain the breast tissue without spillage; straps should not carry all the weight.

   

• If fit seems off: try sister size (band up + cup down or band down + cup up).

   

• Re-measure periodically (season change, weight change, after pregnancy or breastfeeding) and before buying a new brand/style.

Wearing the correct size is more than comfort — it supports good posture, confidence, and ensures your investment in a good bra pays off. If you’re shopping online, especially for a brand specialising in larger busts or seamless bras, knowing your correct size is key.
