Quick answer
Confirm that a size chart belongs to the exact product and variant before using it. Preserve the source unit and measurement method, then compare the product measurements with an item that fits—not only with a familiar letter size.
Record each color, size, material, configuration, or included-item combination as a separate row. A variant name is useful only when it stays attached to the matching photos, measurements, price, quantity rule, and weight.
Confirm the chart scope
- Save the product URL, visible code, and date.
- Record where the chart appears and which variant is selected.
- Check whether the chart measures the product, the body, the foot, or the package.
- Preserve the units and labels exactly as shown.
- Look for a stated tolerance, measurement diagram, or model reference.
If the page contains more than one chart, do not choose the one that looks familiar. Record both and identify which product, batch, fit, or region each chart claims to describe.
Use a measurement handshake
Compare like with like: garment chest with garment chest, insole length with insole length, bag width at the same points, and watch case diameter without silently including the crown. Write the measurement method beside the number.
For clothing, compare with a garment that fits in a similar cut. For shoes, note whether the value is foot length, insole length, or outsole length. Body measurements and product measurements are not interchangeable.
Choose category-specific fields
Clothing
Chest width or circumference, shoulder, sleeve, back length, waist, rise, inseam, hem, stretch, and measurement tolerance.
Shoes
Foot-length basis, insole length, width when available, labeled size system, toe shape, and whether socks or insoles affect the recommendation.
Bags
Width, height, depth, opening, handle drop, strap range, interior layout, and a scale reference for curved or tapered shapes.
Electronics and watches
Device dimensions, connector or model compatibility, case size, strap range, region or voltage limits, and included components.
Write variants as rows
Use one row for every combination you might actually choose. Include product code, color as written, size or configuration, material claim, chart reference, measured values, shown price basis, quantity rule, weight basis, and page date.
Keep source color names even when they seem vague. Add your neutral observation in a separate field. Screens, lighting, editing, and surrounding colors can change perception, so a photo is supporting context rather than a color standard.
Convert units once
Preserve the original value and add a converted value in another column. Record the conversion rule and round only at the display stage. Do not repeatedly convert a number between centimeters and inches because each step can introduce unnecessary rounding.
A decimal does not make a measurement exact. Keep any stated tolerance, and mark your own reading from an image as approximate rather than presenting it as the page's measurement.
Choose a decision state
- Comparable: exact product, chart scope, method, units, and required variant fields are clear.
- One answer needed: the product is stable, but one field such as insole basis or garment tolerance remains open.
- Not comparable: the chart scope, product identity, or variant mapping cannot be established.
When one answer is enough, use the inquiry guide. Carry the final variant rows into the MOQ guide and QC comparison.
Questions readers often ask
How should you read a Yupoo size chart?
Confirm the chart belongs to the exact product and variant, identify whether it measures the body or product, and preserve the original units and method.
