The tile is a hand cut subway tile. If you zoom in on the picture, you can see some irregularity of the tiles. Subway tile is basically brick shaped. The proportions from manufacturer to manufacturer vary quite a bit and are widely available. Good luck on your project... Scott

Thanks! I meant are they 3x 6, etc

I'm afraid I don't know the exact size and I no longer have access to this project. It was provided by the homeowner.
