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
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.
Bust − underbust (in) Band 30 Band 32 Band 34 Band 36 Band 38 Band 40 Band 42 Band 44

* 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.

  1. Jennifer

    Rated 2 out of 5 stars

    Not for me

    It was an odd combination of a lot of thin, stretchy fabric that had no structure combined with the rigid underwire. I don't get why the extra fabric all the way up the front strap area. I was looking for something minimal but maybe if they had 1/2 the amount of fabric and just doubled it up for a bit of support, it would be useful.

    Superior comfort

    Fits well. Lightweight microfiber fabric feels breezy-comfortable. 3-hook & eye fastening and under arm bands that are on the broader side smooth my plump body nicely.

    My favorite bra!

    Comfortable even though it has an underwire. And seems like it just disappears on whatever shirt I'm wearing - no lines or bulges. Definitely my new favorite go-to!

    The fabric is fantastic! Comfortable, smooth and flattering. There is no padding so be prepared for a very sheer fit. This is my go to bra when I don't want a pushup or padded bra.

FAQs

What is the purpose of wearing an unlined bra?

An unlined bra is a great alternative to a contour cup bra. Folks looking for fewer layers (and more breathability,) a more natural shape, and anyone who “doesn’t need extra help” (i.e., they don’t want added size from foam) may be the biggest unlined bra fans.

What is the difference between wireless and unlined bras?

The wire and lining are separate bra parts, so you can have both! If you prefer an unlined T-shirt bra with underwire, the 24/7® Classic Second Skin Unlined is a top choice. If you prefer an unlined everyday bra without a wire, the 24/7® Classic Unlined Wireless Minimizer is a surprise favorite. 

When is it best to wear an unlined bra?

They’re not just a warm-weather friend. Unlined bras come in many forms to serve different purposes. We offer everyday unlined T-shirt bra styles, minimizers, and more.

What breast shape is best for unlined bras?

ThirdLove bras will work for most if not all breast shapes. Asymmetric, athletic, round, side-set, and slender breast shapes may work especially well with the 24/7® Classic Second Skin Unlined Bra.

How much padding is in the 24/7® Second Skin Unlined Bra?

The beauty of unlined bras is that they are padding-free. No added bulk, no extra, hot layers. There are no foam cups in the 24/7® Classic Second Skin Unlined Bra, letting your natural shape shine.

How do I find the right unlined bra size?

Our Fitting Room Quiz can tell you in less than 2 minutes, which we especially recommend if you normally wear heavily padded bras and are looking to try unlined for the first time. If you already know your size in a different ThirdLove bra, that is also your unlined bra size.
