Wood and vinyl have lower starting rates than aluminum siding. However, you're likely to find high-end wood and vinyl siding that's more expensive than low-quality aluminum siding. That's because price often increases when quality increases.  On average, wood siding costs $2.25 to $15.25 per square foot, vinyl siding costs $2.50 to $10.75 per square foot, and aluminum siding costs $3.00 to $7.25 per square foot.
