What are the best wood thicknesses for load-bearing outdoor chair legs?

When building or selecting outdoor chairs, the thickness of the wood used for the legs is crucial for ensuring stability and durability. For load-bearing outdoor chair legs, the recommended wood thickness typically ranges between 1.5 to 2.5 inches (3.8 to 6.4 cm). Hardwoods like oak, teak, or maple are ideal due to their strength and resistance to weathering. Thinner legs (under 1.5 inches) may not support heavier weights, while excessively thick legs can make the chair bulky. Always consider the chair's design, expected load, and environmental conditions when choosing wood thickness for long-lasting outdoor furniture.
