Virtual try-on / FIELD GUIDE
Is the size printed on a garment the same as its measurements?
A size label identifies a catalog option; it does not by itself establish the garment’s dimensions or personal fit. Build the chart from the product owner’s measurements and definitions. Do not derive a chart from a model image or invent universal conversions between labels.
Name the chart’s measurement basis
A selectable “M” is a product option, not a universal chest value. State whether each chart describes a body range or the garment itself, and give the unit and measurement method. A flat width, a circumference and a recommended wearer range are different quantities.
For a concrete source example, Patagonia Australia’s chart explicitly describes body size rather than garment dimensions. That is its stated basis, not permission to copy its numbers or label mapping onto another brand. Your chart needs the actual product owner’s evidence.
Do not turn a flat width into a fit claim
Fictional shirt worksheet, not measured stock: the owner’s sample record says size M, chest width 52 cm, laid flat under its defined method. A draft public chart incorrectly labels that value “Body chest: 52 cm.”
| Value or label | What it means in this invented case | What it does not establish |
|---|---|---|
| M | Exact selectable option for this shirt revision | Any other brand’s M |
| 52 cm | Approved flat garment width under the named method | A wearer chest range |
| 52 × 2 = 104 cm | Arithmetic doubling of that width | An approved circumference method or body-fit recommendation |
| 96–100 cm body range | A separate fictional owner-approved recommendation, if supplied | A range derived automatically by subtracting a fixed allowance |
Correct the basis before converting cm to inches or changing the layout. Doubling a flat width does not account for every garment’s construction, stretch or measurement convention. Do not invent a universal ease allowance. If a circumference is needed, obtain the authorized method and public value.
Keep missing size evidence visible to the team
Keep the sample revision, size option, measurement points, garment state and unit with each approved row. A method might specify fastening or whether fabric is stretched; use the owner’s actual protocol rather than this guide prescribing one for every garment.
One M sample does not authorize S and L rows. Hold missing dimensions until the owner supplies the measured or otherwise approved product-specific basis; do not interpolate a grading pattern from an image. Automatically generated copy still needs accuracy review. Keep manufacturing tolerances and personal fit advice separate from this chart.
Check the selector, chart and image together
In a draft listing, select each available option and compare its name and revision with the chart. Read the basis and units on a phone; do not make the shopper infer them from an unexplained “chest” heading. Resolve conflicting rows before release.
A generated model demonstrates appearance, not measured fit. Do not invent model body dimensions or a worn size for a generated scene. Use size-reference coverage and fit-evidence boundaries for the neighboring image decisions. No garment measurement or wearer fitting was performed here.

Frequently asked questions
Does M establish a fixed chest measurement?
No. Use the product-specific option mapping, measurement basis and approved values.
Can I double a flat width to recommend a body size?
Arithmetic alone does not supply an approved garment-circumference method or wearer range. Obtain the required basis separately.
Can I fill missing size rows from one sample or a model image?
Do not invent them. Obtain the owner-approved evidence for the missing options.
