Essential Royce Bra Size Guide | UK & International Conversions

This Royce bra size guide covers UK band sizes 28–48 and cup labels from AA to L across selected Royce collections. While Royce is best known for wire-free bras in the A–L range, some styles (such as first bras and teen ranges) are also produced in AA cup sizes. Royce uses the UK sizing system (including double cups), so once you know your starting size, the charts below show how Royce’s band and cup availability compares across the range. To confirm your current size, start with our Bra Size Calculator then compare Royce with other brands sold in the UK using the Bra Size Converter.

After checking your measurements, use this guide to review Royce’s UK band and cup availability, plus international conversions. For help with measuring and confirming fit, visit our Bra Fitting Advice before choosing your Royce size.
