What Is a 30H in Other Brands?

Bra sizes are not standardized: the same label means different things brand to brand, so your 30H is a starting point, not a fixed size. A US 30H usually needs a 30I in Victoria’s Secret, maps to a 30FF in a true-to-size UK brand like Panache, and stays a 30H in Wacoal.

Common questions

30H conversion questions

What is a 30H in Victoria's Secret?
Victoria's Secret cups run about a full cup small, so a standard US 30H usually needs a 30I there. If you already wear a 30H in Victoria's Secret, your size in a true-to-size brand is likely a cup smaller.
Which brands keep a 30H the same?
In true-to-size brands a US 30H stays a 30H: Wacoal, Panache, Glamorise, b.tempt'd, Maidenform, Fantasie, Gossard, Pour Moi, PrimaDonna, Marie Jo, Anita, Goddess. Fit can still vary by style, so treat the label as the starting point.
Do UK brands size a 30H differently from US brands?
UK brands label cups in a different sequence above D (D, DD, E, F, FF, G), so the same letters can mean different volumes. In a true-to-size UK brand like Panache, a US 30H is a 30FF; the band number stays the same.
What size replaces a 30H in brands that don't use cup sizes?
SHEFIT, Kindred Bravely, ENELL, Under Armour, Nike size by their own charts (XS-XL or numeric) instead of band/cup, so a 30H doesn't carry over directly. Start from each brand's chart with your underbust and bust measurements.
