True-Scale
AI models render jewellery far larger than real life. True-Scale lets you anchor one known dimension in an image, then measure any feature in true millimetres, annotate it, and export a spec sheet. It runs entirely in your browser and nothing is uploaded.
How it works
Anchor a known size
Set one reference dimension in the image, such as a ring's band width or a stone's diameter.
Measure any feature
Draw a line or box over any other feature and read its true size in millimetres, calculated from your anchor.
Export a spec sheet
Save an annotated spec sheet with every measurement, ready for a maker, a caster, or a quality check.
Built for jewellers who are tired of AI renders that lie about size.
