Read the measurements before you buy

Short answer: Measurements in centimetres are the only thing that can be compared across brands. The letter on the label means something different from brand to brand. Find the figures in centimetres before you choose a size.

Centimetres and letters

An M at one brand is not the same as an M at another. The letter is a label each brand defines for itself, and there is no shared standard you can rely on. Centimetres, on the other hand, are the same everywhere. That is why the numbers are the only safe way to compare sizes.

Read the heading first

Some tables give body measurements, meaning how large the body is that the garment should fit. Others give garment measurements, meaning how large the clothing itself is. The difference can be six centimetres in chest width, and that is enough to get it wrong. Read the heading above the table first.

Body and garment measurements

Body measurements are easy to find, since you can measure yourself with a tape around the chest. Garment measurements tell you how large the clothing is, and they require you to compare with something you already own. If you do not know which kind the table shows, ask the shop before ordering a size.

Compare with something you own

Lay a garment you like flat on the table and measure chest width, length and sleeve length. Compare those numbers with the table and you will quickly see which size lies closest to what you are happy with. It is the easiest way to avoid a wrong size. See bamboo clothing for men.

How to measure chest width

Measure chest width flat from armhole to armhole, just under the armpit. The table often gives either the flat width or the full circumference, so check which one applies before comparing. Use a tape that lies flat and do not pull it tight. Write the numbers down so you have them ready at the table.

How big a difference is fine

Two centimetres is barely noticed. Four is noticed. Six is another size. That is a good rule of thumb when you compare your own clothes with the table, and it makes the choice easier when two sizes lie close together. See bamboo clothing for women and bamboo loungewear for men and compare the numbers.

If only letters are given

Then write to the shop and ask for the measurements in centimetres. A good answer contains numbers and not just a recommended size. If you have a garment that fits well, send its measurements along, so the shop can compare for you and tell you which size lies closest.

Length and sleeves

Chest width is not the only thing that counts. Length decides whether a top covers the way you want, and sleeve length decides whether it suits your arms. If you are tall or short, these two measures often matter more than the letter itself. Measure them on your own clothes the same way as chest width.

When you are between two sizes

Choose by the measure that matters most to you, often chest width. If you are unsure, think about whether you prefer clothes to fit close or loose. It is your decision, and it is far easier when you have numbers in front of you rather than a single letter on a label.

Frequently asked questions

What if only letters are given?

Then write to the shop and ask for the measurements in centimetres. Only numbers can be compared, and a letter alone does not say how the garment fits your body.

Do you measure over or under the arms?

Chest width is measured flat from armhole to armhole. The number gives the width of the garment, so you can lay a piece flat and compare it directly with the table.
