US to UK Bra Size Converter

Our US to UK Bra Size Converter simplifies navigating international lingerie standards. Because bra sizing varies significantly by country—a common challenge when shopping globally—this tool provides an accurate, side-by-side conversion.

Simply select your known size (either US or UK) from the respective dropdown menus. The system instantly cross-references established industry standards to give you the corresponding international fit. For example, if you know you wear a 36DD in the US system, the tool will immediately show its equivalent range within the UK sizing structure.

The conversion isn't just a single letter change; it accounts for both band size (e.g., 32 vs 34 inches) and cup volume, ensuring you receive the most accurate estimate possible before ordering online.

To maximize the accuracy of your conversion and ensure a perfect fit, preparation is key. We recommend following these steps before using the tool:

• Measure at the Right Time: Measure your bra size when you are fully supported and comfortable—not right after a workout, which can temporarily change measurements.
• Understand Your Body Shape: Remember that the ideal fit often requires considering both your ribcage measurement and your bust measurement separately.
• Know Your Goal: Are you looking for everyday comfort or maximum lift? Some brands specialize in different areas, and knowing this helps narrow down potential sizes provided by the converter.

If possible, consult a professional fitter at a local store first to establish your baseline measurements before relying on online conversions.
