What size do you usually choose for indoor marble flooring

The size of marble tiles for indoor flooring can vary depending on personal preference and the specific design of the space. However, common sizes for marble tiles used for indoor flooring are typically 12 x 12 inches (30 x 30 cm), 18 x 18 inches (45 x 45 cm), and 24 x 24 inches (60 x 60 cm). Additionally, there are also larger format tiles available for more expansive spaces, such as 36 x 36 inches (90 x 90 cm) and 48 x 48 inches (120 x 120 cm). Ultimately, the size of the marble tiles chosen should be based on the specific needs and design goals of the project.
