The Knix Size Chart, Interactive
Knix sizes its wireless bras in its own 1-to-8 system: each number a bundle of neighboring band-and-cup sizes. This chart unpacks the bundles into the measured grid underneath, so you can enter Knix's system from a real measurement instead of a guess.
Every Knix size: tap for conversions
Knix's wireless lines have sold in numbered sizes (1–8+): a labeling Knix has since moved away from in favor of alpha sizes, though numbered charts still circulate at some stockists; this grid is the measured equivalent either way.
Your size at Knix
Same published math as the calculator (snug measure, no +4) then translated into Knix’s native notation and checked against the real chart above, which lights up your cell.
How Knix sizing reads
Knix’s chart reads band-then-cup in inches and US letters: the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation.
The alpha wrinkle: Knix has cycled through labeling systems: the numbered sizes (1–8+) are its earlier convention, still visible in stockist-hosted charts, while current lines sell in alpha sizes; either way each label bundles a band-and-cup zone, and this chart shows the equivalent measured grid the bundles cover. Between Knix sizes, choose by band: wireless support lives there.

Where this chart ends
For underwire structure beyond DD, the specialist brands take over. And if a symptom (riding band, gaping cup, poking wire) sent you size-hunting, the fix guides decode it before you spend anything.
Knix sizing: answered
Does Knix run true to size?
Band: Bands run true to size: start with your measured band on the loosest hook. Cup: Cups grade true to the measured difference. In one line: grading runs true to measurement: start exactly at your measured size.
What sizing system does Knix use?
Native US sizing (it reads band-then-cup in inches and US letters) the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation. The interactive chart above shows every size with its US, UK, EU and FR equivalents.
What sizes does Knix carry?
30–44 bands with A–DD cups in US notation. 40 sizes in the core chart. Knix's wireless lines have used numbered sizes (1–8+), an earlier labeling now giving way to alpha sizes; this grid is the measured equivalent of both.
What if Knix doesn't make my size?
For underwire structure beyond DD, the specialist brands take over. Sister sizes (same volume, different band) sometimes bridge a one-band gap: the calculator above tries them automatically before giving up.
