How to Tell If Lumber Is Hard or Soft: Key Differences and Tests
Learn how to identify hardwood vs. softwood lumber using the Janka hardness test, grain patterns, weight, and tree types in this quick guide.
92 views
To determine if lumber is hard or soft, refer to the Janka hardness test rating, or use a practical method: hardwoods often have visible grain patterns and are heavier, while softwoods are typically lighter and less dense. Additionally, hardwoods come from angiosperm trees (deciduous), and softwoods come from gymnosperm trees (conifers).
FAQs & Answers
- What is the Janka hardness test? The Janka hardness test measures the resistance of wood to denting and wear by pressing a steel ball into the wood surface and is commonly used to compare lumber hardness.
- How can I visually identify hardwood versus softwood? Hardwoods often have more visible and complex grain patterns and are usually heavier, whereas softwoods tend to have lighter color and less dense grain structures.
- What types of trees produce hardwood and softwood? Hardwoods come from angiosperm (deciduous) trees, which have broad leaves, while softwoods come from gymnosperm (coniferous) trees, which usually have needles and cones.
