What George says about its sizing

In a 2023 trade-press feature, George described a lingerie range of 37 sizes, with bras starting from about £5. It said that because most of the shoppers it surveyed had never had a professional fitting, its in-house team built an online buying tool to help people find their size, and that customers should then be the same size across the George range.

That makes George a convenient place for everyday, inexpensive bras, provided you start from a size that suits you.

Find your starting size at home

  1. Measure your underbust snugly, directly under your bust, tape level. Round to the nearest even number. That is your band. Add nothing to it.
  2. Measure your bust around the fullest part, tape resting lightly.
  3. Subtract the band from the bust. Each inch is one cup: 1 is A, 2 is B, 3 is C, 4 is D, 5 is DD, 6 is E.

The UK bra size calculator does the sum in inches or centimetres. The full method is in how to measure your bra size.

If George's tool gives a different size

Size tools use different rules. If a tool's band is two or more inches bigger than your underbust measurement, it is probably adding inches, which tends to give a band that is too loose and a cup that is too small. Try both sizes and let the fit decide. The reasons are in why the +4 method is wrong.

Frequently asked questions

Does Asda have a bra size calculator?

George at Asda has published an online buying tool to help customers find their bra size. It is Asda's own tool and is linked to its own range. You can use it, use our calculator, or both, and compare the results.

What sizes do George at Asda bras come in?

George has described its lingerie range as covering 37 sizes. The exact bands and cups differ from style to style, so check the size list on the product page or the size guide on the George website.

Are George bras the same size across the range?

George has said customers should be the same size across its range once they find their size. In practice, moulded, padded and non-wired styles fit differently on most bodies, so it is worth checking each new style on.

Can I get a bra fitting at Asda?

We have not found information on an in-store fitting service. Measure at home and use the fit checks on this page, or book a free fitting elsewhere if you want one in person.
