It is NOT 3 inches wide! It is only 2 38 inches wide. The description on Wayfair is obviously quite wrong.

I loved it so much that I ordered 40 pieces for my project! I was happy to find a longer length (12") and width (3") for a trim tile. Plus I had color choices, and it shipped quickly! Can't go wrong with this one.

This was great, packaged well and beautiful color. I had to return it because the tile that it matched was out of stock. I will purchase again when I get the matching tile with it.

The color is exactly as I had hoped and I can’t wait to have it installed. The quality looks very good, the tile is made in Spain. I could not find this light blue color anywhere else.

I love the finish of the porcelain chair rail. It isn't too bright, and not too yellow.
