Main differences:
- Origin: Douglas fir comes from North America but has become widespread in Europe in recent decades, while Larch originates from Europe and Siberia
- Durability: Larch naturally resists moisture better
- Density: Larch is denser (550–600 kg/m³) than Douglas (450–500 kg/m³)
- Appearance: Douglas fir has contrasting grain, while Larch is more uniform
- Usage: Douglas fir is preferred for structural use, Larch for decorative interior applications
These differences in quality and origin influence their respective prices, with Larch generally being more expensive than Douglas fir for interior design projects.
