How to use the size guide properly
Short answer: Compare centimetres with a garment you already own, not with your own body. It is the fastest and most precise method, because you compare two numbers rather than a number and a guess.
Why the garment beats the body
If you measure yourself, you then have to guess how much ease the garment needs on top. If you measure a garment that fits, you already have the answer. You compare two numbers instead of a number and a guess. A garment also does not move or change from hour to hour.
Find a garment that fits
Find a garment whose fit you like and that resembles what you want to buy. Compare a T-shirt with a T-shirt and a pair of briefs with a pair of briefs. The fabric and cut affect how the numbers should be read, so stick to the same type. See bamboo t-shirts for men to compare.
How to lay the garment out
Lay the garment flat on a table or on the floor without stretching it. Smooth it out with your hand so there are no folds, but do not pull the fabric. If the fabric is pulled, the measurement gives a false number. A calm, consistent measurement matters more than doing it quickly.
Measure the chest width
Measure the chest width from armpit to armpit and multiply by two. That gives the garment's full circumference, which is the number you can compare with the size guide. Measuring flat gives half of the width, which is why you multiply. Write the number down so you have it next time.
Measure the length
Measure the length from the shoulder seam to the hem. That is the second number, and it tells you how the garment sits on the body. Compare it with the guide's length measurement, and note it down next to the chest width, so you have both measurements together in one place.
Body measurements instead of a garment
Some guides give body measurements instead of the garment's measurements. In that case, add two to four centimetres for room to move before you compare. That is a rule of thumb. To be sure, always check whether the guide talks about the body or the garment. See bamboo clothing for women.
Between two sizes
If you sit between two sizes, choose by the most important dimension. It is not always the same for every garment, so think about where the fit matters most. The larger size gives a roomier fit, and the smaller gives a closer one. There is no right answer, only what suits you.
Tops and trousers
In tops, the most important dimension is the chest width. In trousers, it is the waist. That is why you always start by comparing the chest width on tops and the waist on trousers, and only then look at the length. It keeps the choice simple. See bamboo underwear for men.
Keep your measurements
Write your measurements down when you have found a garment that fits. Keep them in a note on your phone with the name of the garment, so you have a reference next time. Then you can compare new guides with your own numbers in seconds and avoid measuring again. Every brand has its own guide.
Frequently asked questions
Should you measure on the outside?
Yes, lay the garment flat and measure across the fabric without pulling. That gives the garment's true measurements, which you can compare with the numbers in the size guide.
What if the guide gives body measurements?
Then add two to four centimetres for room to move. That stops the garment feeling tight when you move, sit down or lift your arms. Read the guide's explanation to be sure.
Is the guide the same for all brands?
No. Every brand has its own guide, so always check the one that belongs to the brand you are buying. A medium can fit differently from brand to brand.
