Bra Size Conversion Chart: US and UK Sizing Explained for Pakistan

If you have ever tried to order a bra from an international brand, or simply come across a US size label and wondered how it compares to what you normally wear, you are not alone. Bra sizing looks similar across countries at first glance, but there are a few key differences worth understanding before you order.

Band Sizes: The Easy Part

The good news first: US and UK band sizes are numerically identical. A 32 band is a 32 band in both systems, a 34 is a 34, and so on. Pakistani retailers, including most local brands, generally follow this same band numbering, so if you already know your band size, it carries over directly without any conversion needed. If you are unsure which band is yours, our guide on choosing between a 32, 34, and 36 band helps you narrow it down.

Cup Sizes: Where It Gets Confusing

Cup letters A through D are the same across US and UK sizing; a US 34C and a UK 34C are the same size. The confusion starts above a D cup. US brands typically continue as DD, then DDD (sometimes labeled E), then F, G, and so on. UK brands instead typically use single letters after D: E, F, FF, G, GG, H, continuing in that pattern. This means a US DDD is often closer to a UK F, not a UK DDD, even though the letters look similar. If you are ordering a larger cup size from an international brand, always check that specific brand's own size chart rather than assuming the letter carries over directly, since this is the single biggest source of ordering mistakes.

A Simple Reference Table

For cups A through D, both systems match exactly: A = A, B = B, C = C, D = D, and band numbers (32, 34, 36, 38, 40, 42) are shared across both. Above D, treat any conversion as an approximation and check the individual brand's chart, since labeling is not fully standardized industry-wide even within the same country.

How Pakistani Sizing Usually Works

Most Pakistani lingerie brands size using the same band numbers as the US and UK (32 through 42 being the most common range), and cup labeling for A through D generally follows the same convention. One thing worth knowing: many Pakistani and South Asian brands sell bras by band size alone, without separate cup grading, especially in everyday and budget-friendly ranges. In these cases, the bra is designed with a standard cup shape intended to fit a typical range within that band size, rather than offering a precise cup letter choice. If you have a fuller or fuller-than-average cup for your band, it is worth checking a product's specific fit notes or reviews, or opting for styles that do offer distinct cup sizing, such as underwire or push-up styles, which are more likely to specify cup letters.

Practical Tips When Ordering

If you know your measurements rather than just a size label, use those to double check fit rather than relying purely on a size conversion, since measurements are more reliable than any label. If you have not measured recently, our step-by-step bra size guide for Pakistani women shows you how, and the bra size calculator gives you an instant result. When in doubt between two band sizes, choosing the smaller band with a slightly larger cup, or vice versa, using the sister sizing method, can help you land closer to a comfortable fit.
