Image size from Unity packagae not what's uploaded into Vuforia

Hi all,

I create in photoshop a rectangular 4.5cmx18cm Image. The 3d Object is also 4.5cmx18cm measured in Maya.

When creating the Image database in Vuforia website I upload this image and enter 0.045cm width (Vuforia uses mtrs as default). I upload the Vuforia image from the unity package created from adding the target. Image and 3d Object scale in Unity are 1.

When looking at these two in the editor, the 3d model looks tiny in comparison. The Image looking at Unity's editor shows 25cmx1meter whilst the 3d model maintains the correct size 4.5cmx18cm.

Can someone please shed some light what I'm doing wrong please?

Thank you for your help,

Sergio
