Bra Size Calculator & Chart

Thirdlove offers over 60 bra sizes from 32 to 44 band and bra cup sizes from AA to H cup, including our exclusive half cup sizes. Using your current bra size as a starting point, you can refer to the bra cup size chart below to refine your fit.

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.

    Support without the hurt

    This is my first ever staapless that had not hurt while wearing. I can wear it all day without if slipping or hurting. It's so comfortable that I forget I am wearing without straps. The band is very wide with helps support and lift. I love the comfort. I love the lift. I love the look this helps me achieve.

    Just the right support!

    I’ve struggled with strapless bras in the past, and this one is definitely the best yet! It stays up properly, and I get even better lift when I use the included straps. Looks great under my clothing, as I tend to be full on the bottom than the top. The band is very secure with 4 hooks so it feels a tad snug, but I think that’s just the design. Overall, it works well for my size and shape!

    Unfortunate miss

    I really like other third love bra styles but this style was an unfortunate miss. Your normal band size will not fit, i wasn’t able to clasp it at all until adding a multi inch extender. Even once I did that, the cups aren’t great. It pushes up but in an unnecessary way that leads to that weird line in your boob. I wouldn’t buy again.

    Stays up perfectly!

    This bra is super comfortable and does not slip at all. Only issue is I think I should have gone up 1/2 a cup size as it runs small.
