What is stronger pine or spruce?

Pine and spruce are both commonly used softwoods, but their strength can vary depending on the specific species. Generally, pine tends to have a higher strength-to-weight ratio, making it stronger than many spruce species. However, some types of spruce, like Sitka spruce, are known for their exceptional strength and are often used in applications requiring high structural integrity, such as aircraft construction. Ultimately, the strength of each wood type can depend on factors like growth conditions and moisture content.
