How do I make a size chart image for a listing?

Upload a front-on photo of the product, give it your real measurements and what each one measures, and the chart comes back with the dimension lines drawn on the product on pure white.

Does it measure my product for me?

No, and deliberately not. You supply the numbers. Estimating a dimension from a photograph would produce a confident wrong answer, which is worse for returns than having no chart.

What measurements should a clothing size chart show?

Shoulder, chest, length and sleeve, taken flat, are the four that answer most questions. Sizing varies so much between brands that the letter on the label tells a buyer nothing on its own.

Is this compliant with Amazon image rules?

It is built for the secondary infographic slot: pure white ground, the product filling the frame, labels level and legible, generous margins. Amazon main images must carry no added text, so use this in a secondary slot.

How much does one size chart cost?

One credit is one image and Starter is $12 for 100 credits, so about twelve cents. The free plan includes 10 image credits a month.

Can it show a scale reference instead of measurements?

Yes. A hand, a phone or a familiar object beside the product answers "how big is it really" faster than a number can, and it works for products where a measurement means little on its own.
