How to measure clothes laid flat: a clearer fit guide for buyers and sellers

A size label is useful information, but it does not tell the whole fit story. A practical starting point is to compare the item with a similar garment you already enjoy wearing. Use the same measuring points on both pieces.

For context, eBay's clothing fit guide notes that sizing varies between manufacturers and countries. Its inside-leg example measures along the seam of trousers laid flat. Our checklist below helps make an individual listing easier to interpret.

Record the method as well as the number

1. Lay the garment on a clean, flat surface and smooth it gently without stretching it.
2. For a top, describe where you measure across the chest and where the length begins and ends.
3. For trousers, state the flat waistband width, the inside-leg seam length and, when useful, the rise.
4. For a dress or skirt, explain the waist measurement and the point used for the overall length.
5. Write the unit beside every measurement. Say whether the figure is a flat width or a full circumference.

For example: "Waistband approximately 38 cm across when laid flat, measured unstretched; inside leg approximately 72 cm along the seam." This is clearer than "waist 38". Do not silently double a flat number and present it as a person's body measurement.

Keep the original labelled size in the listing too. Note an elasticated waist, stretch fabric, an asymmetric hem or alterations that affect the comparison. If a label is missing, say so rather than inventing a size. A photograph of the measuring points can resolve ambiguity.

Measurements still cannot promise comfort, drape or an exact fit. Buyers can ask for one missing measurement before deciding.
