MDF vs Plywood: Which One Should You Choose?
Published on February 10, 2024
When it comes to furniture and construction projects, choosing between MDF (Medium Density Fiberboard) and plywood can be confusing. Both have their advantages, and the best choice depends on your specific project requirements.
What is Plywood?
Plywood is made from thin layers of wood veneer glued together, with each layer's grain rotated 90 degrees. This cross-grain construction gives plywood its strength and stability.
What is MDF?
MDF is made from wood fibers, wax, and resin that are compressed under high pressure and heat. It has a uniform, smooth surface without knots or grain patterns.
Comparison Table
| Feature | Plywood | MDF |
|---|---|---|
| Strength | Very Strong | Moderate |
| Surface | Visible grain pattern | Smooth, uniform |
| Moisture Resistance | Good (BWR grade) | Poor (unless MR MDF) |
| Price | Higher | Lower |
| Weight | Lighter | Heavier |
| Edge Finish | May show layers | Smooth, clean |
When to Choose Plywood
- Kitchen cabinets: Better moisture resistance
- Outdoor projects: Weather-resistant grades available
- Structural applications: Higher strength needed
- Projects requiring strength: Shelving, flooring
When to Choose MDF
- Painted furniture: Smooth surface takes paint beautifully
- Interior projects: Low moisture areas
- Decorative elements: Clean edges for detailed work
- Budget-conscious projects: More affordable option
- Cabinet doors: Especially when painting
Pro Tip
Many professionals use a combination: plywood for cabinet boxes (strength and moisture resistance) and MDF for doors (smooth surface for painting). This gives you the best of both worlds.
Making Your Decision
Consider these factors:
- Location: High moisture areas need plywood or MR MDF
- Finish: Painting? MDF. Natural wood look? Plywood
- Strength requirements: Heavy loads need plywood
- Budget: MDF is more cost-effective
- Aesthetics: Preference for grain pattern or smooth surface
