Bra Size Calculator: Find Your Correct Bra Size

The band should feel firm and secure without digging painfully into your skin. It should sit reasonably level around your body and should not ride up when you move.

The center fastening should sit comfortably against your breastbone. It should not gape open, pull excessively, or press painfully into the skin.

The cups should contain your breast tissue without spilling over the top, sides, or center. At the same time, there should not be large empty spaces between the breast and cup.

The straps should stay in place without constantly falling from your shoulders or digging into them.

If the front closure repeatedly pulls apart during normal movement, check the band and cup size. If the center closure digs in or the cups feel compressed, the size or shape may not be suitable.

Front Fastening Bra Size Guide

Front fastening bras generally use the same UK band-and-cup sizing system as other bras. However, sizing can vary between brands and individual styles, so measurements should be treated as a starting point rather than an absolute rule.

A simple traditional starting point is to compare your bust measurement with your band measurement:

This table is only a general guide. Modern bra sizing can differ because of brand patterns, stretch fabrics, cup shape, and the way measurements are taken.

If you are unsure where to start, you can use our Bra Size Calculator to estimate your band and cup size before shopping for a front fastening style.

After getting a starting size, always check the individual manufacturer's size chart. A 36D in one style may not feel exactly the same as a 36D in another.
