In wholesale stone distribution, full slabs are inventoried and sold as complete units tied to specific slab numbers. When curating stone, beyond falling in love with a slab's color palette and veining, understanding required project dimensions is key to calculating slab counts.
A standard stone slab measures approximately 300 cm × 180 cm (~58 to 60 sq ft), though dimensions vary depending on raw block extraction. For instance, if a living room feature wall measures 350 cm × 250 cm, two full slabs are required to ensure seamless coverage. Remaining material offcuts can be repurposed for coffee tables, vanity countertops, or threshold saddles.
In scenarios where a wall slightly exceeds a single slab's dimensions—where purchasing an additional full slab feels inefficient—we often advise integrating complementary materials such as decorative fluted panels, titanium-coated stainless steel trims, or bronze mirrors. This approach creates an exquisite, layered architectural border.

Natural stone is calculated using the traditional Taiwanese unit of area, the cai (30 cm × 30 cm, equivalent to ~0.09 sq m or 0.97 sq ft). Material prices range from NT$200 to over NT$4,000 per cai. Because a standard 300 cm × 180 cm slab yields roughly 60 cai, single-slab material costs range between NT$12,000 and NT$240,000+.

Three primary factors govern this price variance:

1. Quarry Yield & Rarity: Supply and demand dictate market value. When rare quarries produce exceptional slabs with intact crystal clarity, origin prices reflect that scarcity. Conversely, abundant commodity quarries supply budget-friendly options, typically priced around NT$200–300 per cai.

2. Geological Grading: Slabs extracted from a single quarry undergo grading similar to diamonds. Quarry owners categorize blocks into Grade A, B, and C based on crystal density and visual perfection—explaining why the same stone species commands different price points across the market.

3. Processing & Finishing Standards: Standard domestic supply chains often import raw blocks (gangsaws) to process locally. To guarantee uncompromised quality, CHENHOW MARBLE imports over 80% of its curated inventory as finished, factory-processed slabs from Europe and South America. While international finishing increases logistics costs, it ensures superior surface calibration and mirror polish quality.
