Apoio Sizing Guide: How to Measure Bra and Panty Size for Kids & Teenagers at Home

If you are a parent looking for the right teen bra size guide for your teenager, we understand it can feel daunting. Teenagers are growing and developing, so age alone can’t be the only factor in determining their size or what will suit them best. Innerwear should be made of breathable, soft material. While wearing the innerwear, the teenager must feel comfortable, and it should provide appropriate support and freedom of movement without the constant need to adjust it. 

At Apoio, comfort and adequate support for teenagers are our main focus. That is why Apoio’s sizing chart is beyond age and focuses on body build and measurements.


When parents decide to buy a first bra for their daughter, their first step is to look out for the average bra size for 10-year-old girls. A single bra size can’t fit every 10-year-old; every teenage body build, measurements, and development vary. Apoio’s sizing guide for the bra, along with age, gives emphasis on chest and waistband measurement so that the teenager gets the correct fit. 

How to Measure Bra Size at Home 

Step 1: Measure the Chest 

Take the measuring tape and wrap it around her chest, keeping in mind that the tape is comfortable and not tight. Ask her to stand correctly and straight without bending or changing her posture. While making sure the tape doesn’t twist, note down the measurement in centimetres or inches, whatever you prefer. 

Step 2: Waistband Measurement 

Once you have taken the chest measurement, check where the waistband will fit and keep in mind that the tape around the body is comfortable. You can check out Apoio’s size guide, whose range is from 22- 24 inches for 7–8 years, 24–26 inches for 9–10 years, 26–28 inches for 11–12 years and 28+ inches for 13+ years. This is not a standard sizing guide; this is Apoio’s product sizing guide. 

How to Measure Panty Size


Panty or bottomwear size depends mainly on the waist rather than the chest size. 

Take the measurements around the natural waistline or at the place where the waistline of the chosen style sits. Ensure that the tape is snug but comfortable and not loose. 

In case of Apoio’s bottomwear, currently the size chart is based on the waist measurements: 21-23 inches for 7-8 years, 23-25 inches for 9-10 years, 25-27 inches for 11-12 years and 27-29 inches for 13+ years. 

If the measurements lie between two sizes, consult the size chart for the particular product and opt for the size that provides comfortable movement without any restriction. 

Bra and Panty Combo Selection 

bra and panty combo is a great way to choose when you are looking for daily innerwear. But, bras and panties can’t always come in the same size. For instance, a teenager, based on chest measurement, may require one size in a bra, while based on waist measurement, she might require a different size in panty. 

Hence, Apoio’s sizing guide helps parents know the size for top and bottom wear. Apoio’s Size Finder helps in finding the right size for both top and bottom by focusing on factors like body build, growth stage, measurement and age. 

Teen Bra Size Guide for Parents 

If you are looking for a good bra for your teenager, focus on breathable material, coverage & a fit that is comfortable to wear daily. Teenagers who are into sports or physically active need good coverage, support & mobility. Apoio's active beginner bra, for instance, has adjustable straps, is made of cotton & soft material, and provides freedom of movement for everyday activity. While selecting the bra for her, ask your daughter if she is feeling comfortable or not and also if the bra fitting is loose or tight. 

The Apoio Approach to Growing Up 

Selection of innerwear is not only about matching the measurements from the size chart. It is also about if the teenager is feeling comfortable and confident or not. While choosing innerwear, along with age, keep measurements in mind & always go through the size chart while buying any product.
