Sizing doubts are one of the most common reasons shoppers hesitate and one of the most common reasons they return clothes. This size chart generator turns your own measurements into a clear size guide, with how-to-measure steps, fit notes and advice for shoppers between sizes.

Measure the garment, not a standard chart

Lay each size flat and measure the same points every time: chest or bust, waist, hip, length, inseam. Your own numbers are what shoppers compare against their favourite piece at home.

Fit notes answer what numbers cannot

Is it meant to be oversized? Does the fabric stretch? What size does the model wear, and how tall are they? One or two fit notes often settle the choice faster than the chart.

FAQ

Size Guide Generator: questions sellers ask

Does the size chart generator make up measurements?

No. It builds the chart only from the measurements you give and converts between inches and centimetres exactly. If you give none, you get an empty template with the right columns to fill in.

Can I use a standard size chart instead?

Standard charts vary by brand and country, and shoppers compare against your garment, not an average. Measure your own samples, ideally several per size, and use those numbers.

Does it work for shoes and rings?

Yes. Pick the category and the measuring steps change: heel to toe for shoes, inside diameter or the string method for rings, and object dimensions for bags and furniture.

Can I edit the copy?

Yes. Copy it out and edit it anywhere, or change your input and generate again for a new version.

Which languages are supported?

English, Spanish, French, German, Italian, Portuguese, Dutch and Japanese. Pick one in the Language option.
