Measuring bra size with a tape measure step by step
Short answer: You measure bra size by taking two measurements, one around the ribcage just under the bust and one around the fullest part, and then comparing them with the brand's size chart. Do it relaxed in front of a mirror and write the measurements down before you decide.
Before you begin
Find a soft tape measure that does not stretch and stand in front of a mirror. Wear a thin, smooth bra or none, so the fabric does not change the measurement. Stand relaxed with your arms down and do not pull your stomach in. Have paper and pencil ready so you can write the measurements down at once.
Step 1, measure the band
Place the tape measure around the ribcage just under the bust, so it lies level all the way round. It should sit firm but not squeeze, and you should be able to breathe freely. Check in the mirror whether the tape hangs crooked at the back. Write the measurement down. See the range under bamboo bra without underwire, where you can compare sizes.
Step 2, measure the bust
Now place the tape around the fullest part of the bust, level all the way round and without pressing the bust together. Stand upright and lay the tape lightly. Write this measurement down too. The difference between the two measurements is used to find the cup, but the exact translation is in the brand's size chart.
Step 3, compare with the chart
Take your two measurements and find them in the size chart for the model you want to buy. The chart translates the measurements into band and cup. Do not simply take the size you usually wear, because brands can fit differently. If you are between two sizes, think about whether you want the most calm or the most room.
Step 4, try and adjust
Wear the bra for a whole day and check the signs: the band lies level and firm, the cups hold the bust without cutting in, and the straps do not dig. If something is wrong, go a size up or down in either band or cup. Repeat the measurement if needed and try one pair at a time.
Typical mistakes when measuring
Many measure too loosely so the band comes out too large, or pull too tight. Others forget that the tape must be level and straight all the way round. If you measure the fullest part too high or too low, the cup will be wrong. Measure twice and use a mirror so mistakes are easy to see.
Fabric and washing
Bamboo in clothing is viscose from bamboo, which lies soft and smooth against the skin. Follow the care label, usually a gentle programme without a hot tumble dryer. Use a wash bag, skip fabric softener, which can leave a film on the fibres, and hang the bra to dry so it keeps its shape and size for longer.
Measure again at regular intervals
Your body changes over time, so measure again when you need a new bra or if your current one does not fit as before. It takes a few minutes and gives you a solid basis for the next purchase. See also bamboo sleepwear for women and women's long-sleeved bamboo T-shirt, and measure yourself for them in the same way.
Frequently asked questions
Should I measure with a bra on
Use a thin, smooth bra or none, so the fabric does not change the measurement. Stand relaxed and hold the tape level all the way round.
What do I do if I am between two sizes
Think about whether you want the most calm or the most room, and try one pair first. Brands fit differently, so always check the chart for the model you want to buy.
Is the measurement the same for all brands
No, size charts vary from brand to brand. Use your own measurements and compare them with the chart for the specific model.
