How this classifier works

To start, upload your image. Our AI tool will then predict what paper size a document is.

This pretrained image model uses a Nyckel-created dataset and has 39 labels, including A0, A1, A2, A3, A4, A5, A6, A7, A8 and A9.

We'll also show a confidence score (the higher the number, the more confident the AI model is around what paper size a document is).

Whether you're just curious or building the paper size of a document detection into your application, we hope our classifier proves helpful.
