First decide what the numbers describe

Body measurement

A measurement of the intended wearer, often used as a fit recommendation.

Product measurement

A flat or three-dimensional measurement of the item itself.

Size conversion

A mapping between label systems; it needs the source's own method.

Tolerance

The allowed production variation around a stated measurement.

How to read a Yupoo size chart

A Yupoo size chart should stay attached to the exact album item, model and version it describes. Yupoo measurements are useful only when the unit and measurement points are visible. If a chart is copied into a spreadsheet without its diagram or source, treat the fit as unresolved.

A diagram prevents silent differences

Two sellers may both list “chest 56 cm” while one measures half-chest flat and another lists full circumference. Ask for measurement points and whether stretch, padding or curved structure changes the method.

Keep centimeters and inches labeled. Avoid converting and rounding repeatedly; preserve the original unit beside any working conversion.

Clothing charts need fit context

Record the garment style, fabric stretch, intended fit and the key product measurements. For tops this may include chest, length, shoulder and sleeve. For trousers it may include waist method, rise, thigh and inseam. A model's height and weight can be a reference, but it is not a substitute for measurements.

Footwear needs an internal-length method

EU, US, UK and other labels can vary by model and supplier. Ask which foot-length or internal-length method supports the chart and whether the last differs across men's, women's or children's sizing. Keep the exact model with the conversion.

Bags and accessories use functional dimensions

For bags, record width, height and depth plus whether handles or straps are included. For hats, belts, rings or bracelets, record the adjustment range and measurement point. “One size” should still have dimensions.

Keep the chart version with the quote

  1. Identify the itemAttach code, model and variant to the chart.
  2. Record the sourceSave the page or authorized message that supplied it.
  3. Add the dateA new production version may use different measurements.
  4. Confirm the orderRestate the selected sizes and distribution before relying on the quote.

When two charts conflict

Do not merge them into one table. Check whether they describe different models, production versions, body measurements or product measurements. Keep both sources and ask which chart controls the quoted item. If that cannot be answered, treat sizing as unresolved even when the labels appear familiar.

When a size recommendation is not enough

Words such as true to size, size up or fits most depend on an unstated reference. Use them only as secondary context. If the chart and product measurements are missing or contradict the sample, keep sizing unresolved.
