Warner’s Bra Size Chart & Sizing
One of the oldest names in the category, now a comfort and wireless mainstream brand.
Warner's in numbers
Warner's has been making corsetry and bras since the nineteenth century; today it is best known for wireless and 'no side effects' comfort styles in mainstream sizes.
Your measured size in Warner's
How this is computed: your US size read straight onto the US label, then adjusted for how Warner's typically grades: true bands, true cups.
Where Warner's sits on the size grid
Cups B–DDD. Not every band–cup combination exists; the largest cups usually appear on mid-range bands only.
Best for:
- Wireless comfort
- Value contour bras
- Smoothing at the sides

Warner's labels in United States notation. Rows are bands (US number, US equivalent in brackets); columns are cup letters as Warner's writes them. Each cell links to that size's guide.
| Band | B | C | D | DD | DDD |
|---|---|---|---|---|---|
| 34 (US 34) | 34B | 34C | 34D | 34DD | 34DDD |
| 36 (US 36) | 36B | 36C | 36D | 36DD | 36DDD |
| 38 (US 38) | 38B | 38C | 38D | 38DD | 38DDD |
| 40 (US 40) | 40B | 40C | 40D | 40DD | 40DDD |
| 42 (US 42) | 42B | 42C | 42D | 42DD | 42DDD |
Coverage is approximate to the brand's core collections; the largest cups typically exist on mid-range bands only. US DDD is written DDD here.
Does Warner's run small or big?
Warner's bands run true to size across US bands 34–42: start with your measured band on the loosest hook, and expect it to feel snug for the first week if you are coming from an add-inches size.
Warner's cups grade true to the measured difference from B to DDD: a gap or overflow in the measured letter is a shape signal, so change the cut before the size.
Warner's wires are average width for the US system. Straps: Standard.
