Read a Yupoo size chart only after confirming which product and variant it belongs to. Preserve the original unit and compare the same measurement points. Treat every color, size, material, model, and included-parts combination as a separate row when any field can change the decision.
A letter such as M or a number such as 42 is not a universal measurement.
Confirm the chart scope before reading the numbers
- The chart appears on the same item or a clearly identified source page.
- The product code, model, or style is stated.
- The chart identifies garment, body, foot, insole, or product measurements.
- The unit is visible and consistent.
- The selected option is present.
- The chart date or page date is recorded when available.
If the chart is generic or copied from another page, mark its relationship as unknown.
Use a measurement handshake
Yupoo product measurements become comparable only when four parts match: same object, same points, same unit, and same method. Yupoo clothing measurements taken flat are not body circumference. A Yupoo shoe size label is not insole length. Bag width at the base may not equal the widest point.
Ask for a photo of the measurement method when the point or method changes the result.
Choose fields that fit the category
| Category | Useful fields | Common confusion |
|---|---|---|
| Clothing | Chest width, length, shoulder, sleeve, waist, rise, inseam, and fabric stretch where relevant. | Body measurements mixed with flat garment measurements. |
| Shoes | Label size, foot-length guidance, insole length, width, and model-specific fit notes. | Converting a size label without checking the chart used. |
| Bags | Width, height, depth, strap drop, opening, interior layout, and included strap. | Using a styled photo as scale. |
| Watches and electronics | Case or device dimensions, connector, model, region, compatibility, and included components. | Treating a similar-looking model as compatible. |
Write variants as separate rows
Use one row per decision-relevant combination: product code, color, size, material, model, connector, quantity, and included parts. If a red option uses a different material or a larger size changes the price, it is not the same comparison row.
A parent row may group the product family, but every child row should preserve its own source and status.
Convert units once and keep the source value
Store the original number and unit first. Add one converted value in a separate field and note the rounding method. Do not repeatedly convert a copied value across spreadsheets; small rounding changes can accumulate and hide the source.
Example: keep “52 cm chest width (source)” beside the converted reference. Do not replace it with a rounded body-size assumption.
Choose a size decision state
Comparable
The chart scope, product, option, unit, and measurement points match the intended comparison.
Needs one measurement
The item is stable, but one category-critical field or method is missing.
Not comparable
The chart belongs to another item, the unit is unknown, or two variants were combined.
“Should fit” is not a measurement state and should not replace the relevant service’s current sizing or return terms.
Example: two medium shirts are not yet comparable
Page A lists medium as 52 cm chest width and 70 cm length, measured flat. Page B lists medium as 104 cm chest and does not explain whether that is garment circumference or body guidance.
The values may describe a similar width, but the methods are not confirmed. Preserve both source values and ask Page B which object and method the chart uses before treating them as equivalent.
