Lululemon Sports Bra Size Chart & Sizing
Athletic-wear sizing (0–20) with cup groupings on key styles: the brand people most often ask how to convert a bra size into.
Lululemon in numbers
Lululemon sizes bras like its leggings (numeric 0–20) and, on supportive styles like the Enlite and Run Times, adds cup groupings (A/B, C/D, DD/E). Support is compression-plus-encapsulation; the numeric size fits the ribcage, and the cup grouping fits the volume.
Your measured size in Lululemon
How this is computed: your US size read straight onto the US label, then adjusted for how Lululemon typically grades: firm bands, true cups. This brand sells many styles in alpha sizes (S/M/L or numeric athletic sizes) that fit the ribcage rather than the cup: the conversion below applies to its numbered bra-sized styles; for alpha styles use the brand grid and expect support to fall off above a C or D.
Where Lululemon sits on the size grid
Cups Cup groupings on select styles. Not every band–cup combination exists; the largest cups usually appear on mid-range bands only.
Best for:
- Studio and low-impact
- Running with the Enlite/Run Times cup groupings
- Wearers who want athletic-wear sizing

Does Lululemon run small or big?
Lululemon bands run firm: if you sit between bands, take the larger band with the same cup volume (a sister size).
Lululemon cups grade true to the measured difference: a gap or overflow in the measured letter is a shape signal, so change the cut before the size.
Lululemon wires are average width for the US system. Straps: Adjustable on supportive styles.
