How accurate is the bra size calculator?

Our bra size calculator provides a reliable starting point based on standard measurement methods. However, factors like breast shape, tissue density, and brand variations can affect the final fit. We recommend using the calculated size as a baseline and trying on multiple sizes around it to find your perfect fit.

How often should I remeasure my bra size?

We recommend remeasuring every 6-12 months, or whenever you experience significant weight changes (gain or loss of 5-10 pounds), pregnancy, breastfeeding, or notice your current bras aren't fitting properly. Hormonal changes during your menstrual cycle can also temporarily affect size.

What's the difference between US, UK, and EU bra sizing?

Bra sizing systems vary by region. US and UK sizes are similar for bands A-DD, but differ beyond that. EU sizes use centimeters for band measurement and different cup progression. Our calculator automatically converts between these systems, but always check the specific brand's size chart when shopping international brands.

Why does the band feel tight when I try my calculated size?

A properly fitting band should feel snug but comfortable. If it feels too tight, try the hook-and-eye test: you should be able to fasten it on the loosest hooks and fit two fingers under the band comfortably. The tightness often feels unusual if you're used to wearing a larger band size.

What if my cup size calculation falls between two sizes?

If your measurement puts you between cup sizes, we recommend trying both sizes. Start with the larger cup and assess for gaping, then try the smaller cup and check for spillage. Your breast shape and the specific bra style will determine which size fits better.

Can I use this calculator if I've had breast surgery?

While you can use the calculator as a reference, we recommend consulting with your surgeon or a professional fitter specializing in post-surgical bras. Breast implants, reductions, or reconstructions can significantly alter how standard sizing applies to your body.

Why do I get different sizes with different measuring methods?

Different methods (like the +4 method vs. direct measurement) can yield different results. Our calculator uses the current industry standard of direct underbust measurement for band size. Stick to one consistent method for reliable comparisons, and remember that the best test is always how the bra actually fits and feels.
