Read a badminton shoe size chart before choosing a pair
Keep the size system, chart category and width label with the exact model so that comparisons stay clear.
Keep the whole size label
Write down the shoe's model, item code and fit version. Keep the full size marking beside them, including letters such as US, UK or EU and any men's, women's or unisex designation.
A number copied on its own leaves an important question unanswered: which scale does it belong to? If a seller's menu shows only a number, ask which system and category it uses before selecting it. Keep the answer with the product reference.
Read the chart that matches the product
Open the manufacturer's guide linked to the exact product and check its scope. For example, the ASICS Singapore guide separates men's/unisex and women's shoe charts, with US, EU, CM and UK labels.
Use the category specified for the product. Follow one row or column through that chart, keeping its headings attached. Do not combine a value from one chart with a heading from another. When comparing another brand or version, open its own guide and start a separate note.
Check width codes in their own guide
Width needs its own entry in your notes. In the ASICS guide, men's 2E means wide; the Yonex badminton FAQ describes its 2E as slim. The same code therefore cannot serve as a shared width scale for these examples.
Write the maker's description beside the code. Yonex also explains that models carrying the same size can feel different because their shape and construction differ. Keep the exact fit version when arranging a fitting.
Resolve an unclear measurement before using it
If a guide gives a length, record the unit and read what the measurement represents. Ask whether it describes the foot, an insole, the shoe or a size reference when the explanation is unclear. Leave that meaning unresolved in your notes until it is confirmed.
Follow the measuring instructions supplied for the product. Do not add an allowance taken from an unrelated guide or invent a missing conversion. If the product label and the seller's chart disagree, send both references to the seller and ask which applies to the pair offered.
Finish with five checks
- Have I recorded the exact model and fit version?
- Does the chart cover this product and its stated category?
- Have I kept each number with its size system or unit?
- Have I checked the width code in that maker's guide?
- Are discrepancies resolved and fitting or exchange conditions confirmed?
Use the resulting note to choose what to try, then compare it with your fitting observations. A matching table entry is a starting point; it does not establish comfort during play. Check the hall's footwear rules separately.
