Frequently Asked Questions
What's a board foot?
A board foot is 1" thick x 12" wide x 12" long. Formula: (thickness" x width" x length") / 144. Use our board foot calculator for accuracy.
What wood should I use for my project?
Pine is affordable and easy to work with. Oak is strong and attractive. Maple is hard and durable. Walnut is premium and beautiful. Choose based on budget and project needs.
How do I calculate miter angles?
For a frame: miter angle = 90° / (number of sides × 2). For a 4-sided frame: 45° cuts. Use our miter calculator for complex angles.
