Square floor tiles do not show square on the 3D (Rendering question)

[octavio2]

The following question might be directed to a renderer who might have good experience with these matters:  The attached 3D of a Kitchen shows the floor tiles like they are rectangular in shape with one side longer than the other.  But the tiles are supposed to show square with each side of the same length.  The tiles are shown in the rendering about the correct size, so the issue is of how to make an adjustment somewhere so that the 45 degree tiles show to have equal sides, with both sides on each of the directions matching the shorter side seen in the rendering.

I suspect the issue might have to do with some of the setting(s) on the "Texture Editor" (I haven't figured it out yet), or it might be corrected with another setting somewhere else?.

Any ideas on how to have the tiles shown square on the 3D?

Thanks in advance.

Is this a Perspective Rendering?

It was made using the "Camera" of 3D View, and it is on the 3D Views of the Project Browser.  The Projection Mode under the Properties dialog  says "Perspective".  

If it is a Perspective, is there a way somehow to make these tiles shown "square" even if it require some twisting  somewhere?

Check your Appearence Images Scale. Is Width and Height the same?

In Sample size, I changed the width to 10" and the height to 1'-3" and it worked.  See attached updated attachment.  

Thanks in advance.
