Granite vs marble: which is better
Two premium stones for cladding and surfaces — hardness, water absorption, care and cost compared.
Granite130 $/m²
Marble150 $/m²
Key differences
- Granite is roughly 13% cheaper (130 $/m² vs 150 $/m²).
- Marble is warmer: lower thermal conductivity (2.91 vs 3.49 W/(m·K)).
- Granite handles moisture better: 0.2% water absorption vs 0.3%.
- Granite is stronger in compression (150 MPa vs 100 MPa).
