Rosewood is generally harder than ebony. This conclusion is based on the Janka hardness scale, which measures the resistance of wood to indentation. According to the Janka hardness scale, rosewood typically ranges from 2,200 to 2,700 pounds per square inch (psi), while ebony ranges from 2,350 to 2,780 psi. Despite the higher range for ebony, rosewood is generally considered harder due to its consistent hardness across different species. This consistency makes rosewood more suitable for high-quality furniture and musical instruments, where a uniform hardness is crucial. The Janka hardness test results are widely accepted in the woodworking industry and provide a reliable basis for comparing the hardness of different woods.
