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
32.5 – 34.5 36
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.

    Happy to find cotton

    A cotton bra with some padding has been so hard for me to find so I am grateful for this. I followed the fit guide and it seems the correct size. I dont exactly love the cut and shape of the bra, like I wish the cups were more triangular and less like half circles, dont fully know how to describe it. I think I just don't prefer this design. However, I was so happy to find a cotton bra that fits and feels high quality so far.

    This bra is my new

    This bra is my new favorite. It is comfortable, soft, looks nice under my clothing, fits well, and stays put. The adjustable strap does slip a lot but it is located in the front so it's easy to tighten in a flash.

    Straps will not stay put

    I've been buying from Thirdlove for years but unfortunately this most recent order has been lower quality. The design was changed and the front-facing cinches on the straps constantly loosen and do not stay put. This was never an issue with past designs.

    Pretty comfy daily bra.

    This is my daily work bra, and it's been doing the job pretty well. I might try a different size just to be sure, but this one has been good so far.
