UK Size Guide & Fitting Tips
Next is one of the UK's most popular online and high-street retailers for affordable lingerie. This guide covers Next's bra sizing, their available range, and how it compares to M&S and other UK brands.
Does Next Use Standard UK Sizing?
Yes. Next uses standard UK bra sizing with band sizes in inches and UK cup letters. Their sizing is generally true to size — if you know your UK bra size, you can order your usual size from Next with confidence.
Next is a great choice for budget-friendly everyday bras, with competitive pricing on multipacks. Their online size range is broader than what you'll find in-store.

Sizing Math & Rounding Logic
Our calculator implements the industry-standard **modern fitting method** rather than the obsolete "plus-4" retail formula. Band sizes are derived directly from snug ribcage measurements in inches (rounded to the nearest even number). Cup sizes are calculated using the precise 1-inch difference increments between fuller bust and underbust measurements (e.g. 4" = D, 5" = DD, 6" = E).
Sourced Claims & Studies
Medical and biomechanical research shows that up to **80% of UK women wear the wrong bra size**. According to breast health clinical research from the **University of Portsmouth (Department of Sport and Exercise Science)**, properly fitted encapsulation support reduces vertical breast movement by up to 59%, significantly preventing exercise-induced breast discomfort and cooper's ligament stretching.
