Bra Size & Fit Guide

It is estimated that up to 80% of women are wearing the wrong size bra. Investing in a correctly fitted bra is essential for comfort, support, breast health, improved appearance, and increased confidence. It is recommended that bra size is checked at least once a year to ensure the right size and fit, as changes in weight, pregnancy, and a range of other factors can impact bra size. It is also important you choose the right bra for your body shape and activity, for more information about our bra styles and functions, please see the Lingerie Buying Guide.

Bra Size Calculator

Finding your bra size can be tricky, and what fits perfectly in one brand or style, may not in another. We recommend you get measured in-store by one of our Farmers fitting consultants, however, if you'd prefer to measure yourself, this helpful calculator will give you a good indication of your correct bra size. If you'd like to find out more about our fitting service, please view our In-Store Bra Fitting information.

How To Measure A Bra Size

Wear a non-padded bra and stand in front of a mirror with a measuring tape. Take your measurements (in cms) as shown below and enter them into our helpful calculator, or if you prefer, use the Bra Size Chart below to find your size.

Measure your band size

Measure your chest directly under your bust. Ensure the tape is level and exhale completely.

Measure your cup size

Measure your chest around the fullest part of your bust. Ensure the tape is level all around.

Sorry, we can't identify a standard bra size for you. Try remeasuring, then try decreasing your band size and increasing your cup size by a centimetre or two to allow for the typical margin of error. Otherwise, ask a friend to help or head in for a professional bra fitting at your local Farmers store.

Your measurements are only a guide – but an essential starting point. Bra sizes vary between brands and bra types – visit our instore fitting consultants to help you get the right size and style for your shape.

There is no universal system for measuring bra size, a bra that fits in one brand may not fit in another. Before you buy a bra from a brand you've never tried before, please check the brand-specific Size Guide that is included on every product page.

The Right Bra Fit

A well-fitting bra ensures comfort and support throughout the day. It should not dig into your skin, create painful pressure points, or cause discomfort. The right bra will provide the necessary support without causing any discomfort or irritation.

In-Store Fittings

What You Will Need

Simply head to the Lingerie department and ask one of our bra fitting consultants for a fitting – it is always a good idea to call ahead to ensure one is available. We recommend wearing a normal bra with no push-up features for a more accurate measuring.

Getting Measured

You'll be measured in a private changing room by a trained bra fitting consultant who will measure your chest and around the fullest part and under your bust. This gives you the most accurate starting size possible for you when trying on bras.

If you really can't or don't want to get a fitting, try our Bra Size Calculator above.

The Perfect Fit

After you get your size, your bra fitting consultant will ask you what styles you prefer and suggest a few for you to try. Sizes may differ depending on the bra style and brand so ensure you try the bra first to ensure the perfect fit.
