What is harder oak or ash?

Oak is generally harder than ash. The Janka hardness test, which measures the resistance of wood to wear and denting, shows that red oak has a rating of about 1,290 lbf, while white ash has a rating of around 1,200 lbf. This means that oak is more durable and resistant to damage compared to ash, making it a preferred choice for furniture and flooring in high-traffic areas.
