Size converter

Footwear sizing on these marketplaces is usually published as a foot length in centimetres. Measure once, convert to the row nearest your measurement, and treat the listing’s own guidance as the final word.

Measure heel to longest toe, standing, at the end of the day.

  • Manufacturers differ. The same nominal size can vary by half a centimetre between brands, and listings sometimes print a size that does not match the last it was built on.
  • This table is a general conversion range, not a measurement of any particular listing.

Measuring a foot so the number is usable

Measure at the end of the day, standing, with the weight on the foot being measured. Feet spread under load, and a measurement taken sitting down can be half a centimetre short — which is exactly the margin that decides between two rows in this table.

Measure both feet and use the longer one. Most people have a difference of a few millimetres, and ordering to the smaller foot is the mistake that produces a shoe that fits on one side. Put the heel against a wall, mark the longest toe, and measure the paper rather than the foot.

Why the nearest row, not an exact match

The tool reports the closest row in the table and tells you how far away it is. When your measurement falls between two rows, that distance is the useful part of the output: it tells you whether you are solidly inside a size or standing on the boundary.

On a boundary, the deciding information is not in this table. It is in the listing: whether the seller describes the fit as narrow or wide, whether the last is described as running large, and what reviewers with a similar measurement said. A conversion table tells you where you sit in a general scheme; it does not tell you how one factory cut one shoe.

Where sizing drifts

Marketplace sizing is not one system. Listings commonly print a European size, a centimetre measurement, or both, and the two do not always agree. A listing labelled 42 that also states 26 cm is describing a different shape from one labelled 42 that states 27 cm, and the centimetre figure is the one to trust.

Shoe shape matters as much as length. A pointed last needs more length than a round one to be comfortable, and a chunky sole changes how the shoe sits on the foot even at the same internal length. The row is a starting point for the decision, not the decision.

What this tool does not cover

It covers feet, not garments. For tops and bottoms the useful comparison is chest, waist and length, which is what the apparel size chart provides. Clothing labels are read against body measurements; footwear is read against foot length, and mixing the two methods produces numbers that do not mean anything.

It also does not carry a size across from one brand to another. Two brands using the same nominal size can differ enough that a conversion between them would be a guess. If you are replacing a pair you already own, measure the old pair’s insole and use that number instead.
