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

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.

    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.

    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.

    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.

    Feels great!

    This bra is so comfortable, and I am not rushing to take it off at the end of the day. My only concern is that the straps don't feel very secure, and I don't feel like I have much space to tighten them.

FAQs

When is it best to wear a T-shirt bra?

A T-shirt bra is a great choice for almost any outfit or occasion, offering great shape and comfortable support.

Does the T-shirt bra also push up breasts?

The T-shirt bra does not have bump pads to add a push-up effect. However, the 24/7® Classic T-Shirt Bra still delivers great lift and shape without extra padding.

What are the benefits of ThirdLove's T-shirt bra?

The only T-shirt bra made in half cup sizes, ThirdLove’s 24/7® T-Shirt Bra offers a superior fit. It also has memory foam cups that mold to your shape and no-slip straps.

How much padding is in the 24/7® T-Shirt Bra?

The ultra-thin memory foam cups in the 24/7® T-Shirt Bra deliver great shape and a touch of modesty without adding bulk.

What breast shape is best for T-shirt bras?

ThirdLove bras will work for most, if not all, breast shapes. Athletic, bell, east-west, relaxed, and round breast shapes may work especially well with a T-shirt bra.

How do I find the right T-shirt bra size?

Our Fitting Room Quiz can tell you in less than 2 minutes, but if you already know your size in a different ThirdLove bra, that is also your T-shirt bra size.
