Bra Size Calculator & Chart

Bra Size Calculator & Chart

How To Use The Bra Size Chart

When using the chart to find your bra size, keep in mind:

  • The band size increases as you move from left to right. Move left or right within the row if your band doesn't fit.
  • The cup size increases as you move from top to bottom on the chart. Move up or down the columns if your cups don't fit. In between cup sizes? Go up or down a half-cup! And keep in mind if you want styles that are full coverage or not!
  • Bra sizes that share a row are sister sizes, meaning they share the same cup volume (though they have different cup letters). For example, at a glance they’re all just different bra sizes. However, the row with bra sizes 36C, 38B, and 40A have something in common: they all have the same cup volume but have different band sizes. The same goes for the row with bra sizes 38H, 40G, 42F, 44E, 46D, and 48C.
Bra Size Calculator & Chart

Measure snugly around your rib cage (underbust) and around the fullest part of your bust, in inches. Step 1 gives your band. For step 2, subtract your underbust from your bust and find the difference in your band's column. These are the sizes our Bra Size Calculator gives.

Step 1: Band size by underbust measurement (inches). Each range excludes its lower value and includes its upper value.
Underbust (in) Band size
24.9 – 28.5 30
28.5 – 30.5 32
30.5 – 32.5 34

34.5 – 36.5 38
36.5 – 38.5 40
38.5 – 40.5 42
40.5 – 42.5 44
Step 2: Bra size by band and by bust minus underbust (inches). Each range excludes its lower value and includes its upper value.

* Also the result when the difference is exactly 2.5 in: 30B, 32A, 34AA; 4 in: 36A; 5 in: 38A; 7 in: 40B; 8 in: 42B; 9 in: 44B.

The calculator only gives a size for an underbust over 24.9 in, up to 42.5 in, with a difference of up to 13 in. Blank cells and measurements outside these ranges have no size in the calculator.

    Almost Perfect

    This is the first bra that actually fits my cup size! It fits great and moves with me as I move around. But when I tried to wear it as a criss-cross racer back, it was too tight. The straps are about 1/2 an inch too short which causes the hooks on the band to buckle and bunch up. It’s too tight to wear that way. So I will enjoy this bra in the normal position.

    Soft but totally fine

    The fabric is smooth, the straps and cups still don’t fit quite right, but what can you expect from an online quiz and not actually trying it on first. I bought three recommended bra styles and returned two, the others were laughably ill fitting. This one was mid but my other bras (Natori) were falling apart so I kept it and still will go to my local in person lingerie store to get a truer fit.

    Needs improvements

    I really like third love, but firstly, it’s too expensive for a bra that doesn’t last long. The straps start to lose holding strength after a little while and their rigged pattern sometimes digs into my skin and leaves marks.
    I have a cat and his fur always ends up finding their way in between the fabric of the bra, since the material is thin.
    But really what makes me want to look for a different bra maker is that the price is not matching the quality. The offers and promotions are always in favor of the brand and not enticing at all.

    This one has some give!

    The fabric on this is so buttery and smooth and it really prevents "back fat. " Because of the give I realized I can go down in the band size, which is great because I'm inbetween band sizes currently. I want this one in every color because it is the perfect style for dresses, t-shirts, and sweaters!

    Great fit and very comfortable,

    Great fit and very comfortable, only flaw is that the cups are a bit too thin to prevent nipple show. Great bra for looser tops, not so great for tighter/thinner tops.
