HI Joseph

Thank you for writing and thank you for your interest in The Tile Mural Store.

It can come in any square dimension that is evenly divisible by a tile size. On Houzz.com it is only available as a 12.75" x 12.75" or an 18" x 18" but you can find other sizes on our regular website here and if you need it to be larger than the largest size shown we can complete your order over the phone.

Thank you again for your interest in The Tile Mural Store.

Have a great day!

Toni
