Can you direct me to the written spec for the definition of large-format tile? I can not find this in my TCNA Handbook and was hoping to show a written spec as opposed to my spoken word. I appreciate any info you may have for me.

ANSWER:
This is a great question. With the introduction of ANSI A108, A118, A136 specifications in January 2024, the new Section A108.T, American National Standard Terminology of Tile Assemblies – 2023, lists the definition as follows: Large Format Tile: A tile manufactured in conformance with ANSI A137.1 having a facial dimension greater than 23 in. (584 mm).
