Find Your Perfect Fit With Our US to UK Bra Size Conversion Chart
We all have moments when we struggle with bra sizing while online shopping. Bra sizing can be at times both confusing and stressful, especially when we’re trying to figure out sister sizing and converting our bra sizes. Recently, we spoke about bra sister sizing and included an easy to use bra sister size conversion chart. Our chart uses UK sizing to help you determine your sister size in another UK sized brand.
While UK bra sizing is utilized by most full figured lingerie brands (like Parfait, Panache, Goddess, Fantasie), brands with products that use US bra sizing (like Wacoal, Natori, Felina, Blush) also cater to larger cup and band bra sizes. No matter where you’re buying your bras (whether it’s online or at a specialty store), it’s important to know how to convert your bra cup size from US to UK sizing.
What is one of the most important differences between UK and US sizing?
Many of us might not know that there are differences between US and UK sizing. For example, did you know that a US 36DDDD/G bra is equivalent to a UK 36F? When UK bra sizes get bigger, the cup sizing starts to look different.
A typical UK bra size chart looks something like this:
UK bra sizing can include cup sizes AA, A, B, C, D, DD, E, F, FF, G, GG, H, HH, J, JJ, K…
A typical US bra size chart looks something like this:
US bra sizing can include cup sizes AA, B, C, D, DD/E, DDD/F, DDDD/G, H, I, J, K, L, M, N, O…

Converting Your Bra Size From US to UK Sizing
Size conversions are challenging when you’re shopping for DD+ bras. While most brands that use UK sizing produce bra sizes up to a K cup, the majority of lingerie brands in US sizing typically start at an A cup and stop at a DDDD/G cup. Some brands, like Wacoal, go up to a DDDDD/H cup. Converting these sizes into the US size equivalent can be a nightmare if done incorrectly.
Wondering why many lingerie brands that use UK sizing go to up to a K cup and most lingerie brands that use US sizing only go up to a G or H cup (the equivalent of a UK F or FF cup)? It’s not because of a lack of demand. Many UK brands start their sizing in a 26 or 28 band and go up to a 42 or 44 band. Since each new size adds an additional cost for the brand (cost of the pattern, cost to produce the bra, etc), most brands stop at a G or H cup and either slowly add additional sizes (always worth it to come back to a brand you like to see if they’ve increased their size range) or stick with the sizes they have if it’s too expensive for them to expand.
Brands that sell bras in UK sizing typically offer FF, GG, HH, and JJ cup size options. Don’t let the letters fool you – though they use a different lettering system, the cup size equivalent is essentially the same (example: UK K cup and US O cup have the same cup volume).
No matter which brand you’re shopping, bra size conversions can be difficult and confusing. To make conversions easier, we’ve created a simple bra size conversion chart for converting US bra sizes into UK bra sizes or UK bra sizes into US bra sizes.
