King Size and Modular thin bricks both deliver the timeless look of masonry, but their dimensions impact efficiency. Modular size (7 5/8" x 2 1/4") is the U.S. standard, versatile and traditional. King Size (9 1/2" x 2 3/4") covers 25% more area per pallet, with fewer bricks and joints, making installation faster and more cost-effective. Both options bring beauty and durability — the choice depends on your project needs.
