Bra size chart

Calculator on a separate page: bra size calculator.

On this page, you will find a bra size chart in EU, UK, FR, and US notations, a size calculator, a sister size chart, and a panty size chart. All you need are two measurements and a tape measure.

Bra Size Calculator

The calculator provides an approximate result. Brands' sizing varies, so the manufacturer's chart accompanying the product takes precedence.

How to Measure Yourself

  1. Underbust circumference: Measure horizontally, snugly, directly under your bust. This result determines the band size (e.g., 75).
  2. Bust circumference: Measure loosely, at the fullest part of your bust, ideally in a non-padded bra. For a large or soft bust, also measure while leaning forward and use the larger result.
  3. Subtract the underbust circumference from the bust circumference. The difference determines the cup size.

Underbust Circumference

63–67 65
68–72 70
73–77 75
78–82 80
83–87 85
88–92 90
93–97 95
98–102 100
103–107 105

Example: EU 75C = FR 90C = UK 34C = US 34C. EU 80F = FR 95F = UK 36E = US 36DDD. US sizes vary among manufacturers, so treat them as a guide.

Sister Sizes

Sister sizes have a similar cup volume with a different band size: down one band size and up one cup size (or vice versa).

Symptoms of a Poorly Fitted Size

  • Band rides up at the back: band is too loose, choose a smaller size (e.g., 80B → 75C).
  • Band digs in: band is too tight, choose a larger size (e.g., 70D → 75C).
  • Breast spills out at the top or sides, gore lifts: cup is too small.
  • Cup wrinkles or gaps: cup is too big or the style doesn't suit your breast shape.
  • Shoulder straps hurt: usually due to a loose band, which transfers weight to the shoulders.

A well-fitted bra is supported by the band, not the straps; the underwires do not dig into the breast. Details in the guide how to choose a bra size.

Manufacturers indicate tights sizes based on height and weight or hip circumference – check the product's size chart. We discuss tights denier in the guide tights denier.

Most Frequently Asked Questions About Bra Size

My measurement falls between two sizes. Which one should I choose?

For the band, generally go for the smaller size, as bras tend to stretch over time. For the cup, generally go for the larger size. It's best to try on both sizes.

Is the size the same across all brands?

No. Selene, Marilyn, Mat, Kris Line, and other brands have their own sizing. If a manufacturer's chart is provided with the product, it takes precedence.

How do I convert UK size to Polish size?

Band: UK 32 = EU 70, UK 34 = EU 75, UK 36 = EU 80. Cups up to D are the same, beyond that UK DD = EU E, UK E = EU F, UK F = EU G.

What if the size doesn't fit after purchase?

You have 14 days to withdraw from the contract. If you need a different size, return the product and place a new order. Details in frequently asked questions.
