Elomi Bra Size Chart & Size Converter (UK, US, EU, AU)

Elomi Cup Size Conversion Chart

This is the cup sequence from Elomi’s official international size guide. Read across a row to convert a cup letter on the same band:

UK and Australian sizing double letters (DD, FF, GG, HH, JJ, KK), while US sizing goes DD, DDD, then continues with single letters from G. European and French sizing use one letter per step. So an Elomi UK HH is a US L and a European L. Our global bra size converter covers every system and brand.

Elomi cup conversion: UK to US

Elomi Band Size Conversion Chart

UK and US bands share the same numbers. European and Japanese bands go up in steps of 5 for each 2-inch band size (UK 32 = EU 70), French bands are the European figure plus 15, and Australian bands follow dress sizes (UK 32 = AU 10). These are the same rules used across our methodology and the Australian bra size chart.

Find your UK band on the left and your UK cup along the top. Each cell shows the US and European equivalent from Elomi’s chart, split into two tables for easier reading on a phone.

Elomi Sizing: Worked Examples

Example 1: from a US size. You wear US 40DDD. The band stays at 40, and on Elomi’s chart US DDD sits with UK E, so you order UK 40E. Ordering a UK 40F would be one cup too big.

Example 2: from a US I cup. You wear US 38I in another full-bust brand. US I sits with UK G, so your Elomi size is UK 38G (EU 85I, FR 100I).

Example 3: from measurements. Your snug underbust is 40 inches, so your band is 40. Your full bust is 49 inches: 49 − 40 = 9, which is nine cup steps (A, B, C, D, DD, E, F, FF, G). That gives UK 40G, which is US 40I and EU 90I. If the 40 band feels too tight on the loosest hook, the sister size UK 42FF keeps the same cup volume on a looser band.

Example 4: from a European size. You wear EU 95J. EU 95 = UK 42, and EU J sits with UK GG, so your Elomi size is UK 42GG.

Example 5: from an Australian size. You wear AU 20FF. AU 20 = UK 42, and Australian cups use UK letters, so your Elomi size is UK 42FF, or US 42H.

Notice how the same physical cup gets a different letter in each system. That is why we always convert using the brand’s own row-by-row chart rather than by counting letters.

Why Full-Bust Brands Use UK Sizing

UK sizing is the most common system among full-bust specialists, and there is a practical reason. UK lettering is consistent above DD: every cup step is one inch, and the doubled letters (FF, GG, HH, JJ, KK) are simply extra steps in the sequence. US sizing is far less standardised at the top end. Some American brands go DDD, then G, as Elomi’s chart does, while others use DDDD or F after DDD. The same US letter can mean different cups from one brand to the next.

So if you wear fuller cups, the most reliable approach is to learn your UK size and use it as your reference. Convert to a US letter only when a retailer forces you to, and use the brand’s own chart when you do. Our UK bra size calculator gives your UK size directly from your measurements.

How an Elomi Bra Should Fit

With fuller busts the band matters even more, because it carries most of the weight. If straps dig in or you feel it in your shoulders, see straps digging in and band riding up on a large bust.

Elomi Sister Sizes

Sister sizes hold the same cup volume on a different band: one band down and one cup up, or one band up and one cup down. In UK letters, DD, FF, GG, HH and JJ are full steps of their own.

Use sister sizes to fix the band only. If the band fits and the cups do not, change cup on the same band. The sister size calculator works for any size.
