Reading the size chart for knickers correctly and avoiding wrong purchases

Short answer: A size guide for knickers is a table that matches your measurements to a size. Use your hip measurement as the starting point, read which measurements the chart actually lists, and check whether they are for the body or for the garment. That avoids most wrong purchases.

What a size guide for knickers actually shows

Most charts show body measurements, meaning how big you need to be to fit the size. Some show the garment itself, measured flat. Read the heading above the numbers first, because it decides how you should measure and which figure you should compare.

Find the right body measurement

Measure around your hips where they are widest and around your waist where it is narrowest. Use a soft tape measure and let it lie flat without pulling. Enter the numbers in the chart for bamboo knickers and see which size you are closest to.

Centimetres, inches and EU sizes

Some charts use centimetres, others inches, and a few show letters and numbers together. Make sure you compare the same units, otherwise you end up with the wrong size even though your measurements are right. Convert if needed and write the result down before you order.

When two measurements point to different sizes

If hips and waist fall in different sizes, go by the hips for knickers, since they decide how much fabric is needed. If you are unsure, think about the cut. A high cut forgives a little more at the waist than a low one.

Elastic and fabric quality affect the choice

A brief with soft elastic and fabric with some stretch can forgive half a size, but a stiff material cannot. So read the product description together with the chart. If it says nothing about stretch, choose the size that fits your measurements without having to stretch the fabric.

Typical wrong purchases and how to avoid them

The most common mistake is ordering by habit instead of by the chart. Another is assuming that another brand's chart applies here. Always go to the chart on the specific product page, and measure yourself every time you order something new.

Compare with your best pair

If you have a pair that fits well, lay it flat and measure the width. Compare the number with the chart if it lists garment measurements. It is a simple check that stops you guessing from a letter. The same method works for bamboo underwear for women.

If it still does not fit

If the knickers do not fit, note where: too tight at the waist, too loose at the leg or too short at the back. That observation helps you choose better next time. Also look at the sizes for bamboo T-shirts for women, but check that chart separately.

Frequently asked questions

Which measurement matters most when choosing knickers?

Usually the hip measurement, because it decides how much fabric the knickers need. The waist measurement is a supplement, especially if there is a clear difference between hips and waist.

Should I choose by letter or by number?

Choose by the measurements in the chart, not by the letter. Letters differ from brand to brand. Find your measurement in the chart on the specific product page and follow the size it points to.

What if I am between two sizes?

Pick the larger size if you want the knickers to sit loosely and the smaller if they should sit firmly. Also think about the cut and the stretch of the fabric before you decide.
