Why does my USDZ 3D model wrong scale in online tools?

USDZ 3D models often have wrong scale in online tools due to mismatched unit settings between your original modeling software and the online viewer. This happens because tools like Blender (default: centimeters) and most online viewers (expected: meters) interpret USDZ’s embedded scale data differently—making the model too large or small. To fix it, ensure your modeling software’s export units match the online tool’s requirements (check its documentation) or manually adjust the scale in the viewer if available.
