Mesh deforms on final render The object size changes when rendering. The whole object shrinks vertically. I haven't used  Subsurf Modifier. But I did realize that in Render Preview the object size is normal. As soon as I render the image, it is shrinked. 





Blender File: .blend

I hope you can help me with this.
In your render settings you have your aspect ratio set to something other than 1 and 1 for the X and Y values. This will scale the image while rendering and give you the result you are seeing.
