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

28.5 – 30.5 32

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.

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.

    Thirdlove has solved a tremendous

    Thirdlove has solved a tremendous gap in bra coverage — literally and figuratively — by being the only bra company I know of to offer half sizes. My B-and-a-half bra is absolutely perfect, providing the right amount of coverage without the gaping I usually experience with bras once all that breast tissue I arranged perfectly slides back into its most comfortable position. This is life changing — and I love the ribbed straps even if their function is more performative than successful.

    Comfortable, but . . .

    I love the look, feel, and fit of this bra, but the straps are long and slip out of adjustment. I’m very petite, and while I can get the straps short enough, I cannot get them to stay there. It’s a problem I’ve had with other Third Love bras.

    Comfortable and cute

    Looks great and the color is unique but still neutral. Very comfortable. The only reason I give this a 4 star instead of a 5 is that the cups cut slightly into the breast and it's not uncomfortable but you can kind of see it through a thinner t-shirt.

    This bra is so comfy.

    This bra is so comfy. I got it in 4 different colors and each color is just beautiful.
    I have never loved my boobs but wearing this bra gives me such comfort and confidence.
    I initially ordered the wrong size and the exchange process was so easy and the customer service was phenomenal. Love this brand.

    The cup material is pretty

    The cup material is pretty thin and can expose some nipple, which I'm not a huge fan of. Otherwise this is a very comfy bra I could see myself wearing every day.

I've been wearing these for year

"These are my favorite everyday bras, hands down. I love the flexible straps and the 1/2 cup sizing. Also, they hold up for a very long time. I wash them in a mesh bag with my regular laundry and then air dry."

— Anica M. (5/5)

Repeat buyer

"The only complaint I have about this bra is underwire pokes through, but this is after over a year or more of wear. Very comfortable, great fit, smooth feel. Will continue to purchase."

— Becky C. (4/5)

Half size allows for perfect

"Half size allows for perfect fit. Neutral color choices are ideal under any clothing. Comfortable all day. Love the mocha color."

— Kathleen D. (5/5)

Nice bra, but the straps feel uncomfortable

"Nice color selection. The straps feel surprisingly itchy. Not a fan of the texture quality."

— jessica s. (2/5)

Meh - not worth the money

"I recently purchased 3 of these, but kind of wish I hadn't. They are comfortable, however, the "no-slip" straps, slip ALL the time - a problem I've never had with any other bra. The cups aren't as lined as I'd like, so nipples can still be seen and the fabric on the cups, while soft, creases a lot and looks rather messy. Overall, comfy but way too expensive to have so many flaws. Not buying again."

— Karen (2/5)
