Step-by-Step Measurement Guide

If you’re ready to get your exact measurements, grab a flexible measuring tape and follow each of these steps. Then, you’ll be able to compare the numbers to a bra size chart for better accuracy when shopping.

  1. Wrap the measuring tape snugly just under your breasts for the underbust measurement
  2. Next, measure yourself around the fullest part of your bust for bust size
  3. Round both measurements to the nearest inch

Measurement Tips

To get the most accurate measurements for the bra size guide, follow these tips:

  • Stand up straight and breathe normally
  • Remove your shirt and bra, and use the measuring tape against bare skin
  • Make sure the measuring tape is completely parallel to the floor every time

Cup Size Chart

To find your cup size, you’ll need to subtract the underbust measurement from the bust measurement and use the difference to find your cup size on this chart. Cup sizes will indicate the volume of the cup. This interior space needs to comfortably support, lift, and enclose your breast shape.

Difference in Inches Corresponding Cup Size Difference in Inches Corresponding Cup Size
0 AA 6 F
1 A 7 FF
2 B 8 G
3 C 9 GG
4 D 10 H
5 DD 11 HH

When trying on a new bra after following this bra size chart, always check that your breasts are fully enclosed in the cups. There should be enough room for each breast without any gaping or overflow. If you’re experiencing gaps, consider a smaller cup size. For those with overflow, look at sizing up your cup.

Band Size Chart

Now that you understand how to get the right cup measurement for a bra size chart, let’s talk about your band size. The band size is your underbust measurement. Since bra manufacturers don’t create bras for every single underbust measurement, you’ll need to match your underbust number to the range in the chart below to find your size:

Underbust Measurement in Inches Bra Band Size
25-28” 30
29-30” 32
31-32” 34
33-34” 36
35-36” 38
37-38” 40
39-40” 42
41-42” 44
43-44” 46

Variable Sizing Options

Since bra sizes can vary by style, brand, and country, you’ll need to reassess your bra fit regularly to match the bra size chart wherever you happen to be shopping. In addition to variation by brand or style, you should also remember that sister sizes can deliver a better fit.

Sister sizes are alternative options that offer the same cup volume with a different band size. See the bra size guide below for some examples of sister sizing that may result in a more comfortable or supportive bra:

Original Size Sister Size
32B 30C
34B 32C
36B 34C
34C 32D
36C 34D
38C 36D
34D 32DD
36D 34DD

The general idea behind the sister bra size chart is that you can decrease your band size by one while increasing your cup size by one.

Final Fit Tips for the Perfect Bra Fit

If you’re ready for a comfortable bralette and the perfect fit, make sure your bra meets all these tips, including:

  • Your bra band fits snugly while staying parallel to the floor, no riding up!
  • Adjust every part of the bra you can, including straps, band, and hooks.
  • Underwire should sit flat against your chest without digging into your sides.
  • Your breasts should sit comfortably in the cups with no overflow, gaps, or side bulges.

Loose bands and straps can cause your bra to slip and won’t provide the ideal level of support. If you can adjust your bra to fit, great! However, if you can’t find comfort in your current size, consider a sister size or a different bra silhouette instead. Here are a few different bra types to consider:

  • Sports Bras: Ideal for high activity and impact support
  • Padded & Pushup Bras: Lift breasts and enhance cleavage
  • T-Shirt Bras: Designed for invisibility underneath your clothing with smooth, molded cups
  • Underwire Bras: Provide breast shaping and extra support
