The short answer
Use MDF for a smooth painted/shaker finish and stable flat panels; use plywood for strength, screw retention and moisture stability, especially long shelves and wet areas. Many kitchens mix both.
MDF vs plywood compared
| Factor | MDF | Plywood |
|---|---|---|
| Painted finish | Flawless, no grain | Grain may telegraph |
| Strength | Good | Higher |
| Screw holding | Moderate | Excellent |
| Moisture stability | Lower (use MR-MDF) | Higher |
| Weight | Heavier | Lighter |
| Relative cost | Lower | Mid–higher |
Our recommendation
Choose MDF for painted shaker doors and stable panels, plywood for carcasses, long shelves and moisture-prone areas. We build in either or a mix — tell us your priorities.
Frequently asked questions
Is plywood better than MDF for kitchens?
Plywood is stronger and more moisture-stable; MDF gives a smoother painted finish. Many kitchens use both.
Which holds screws better?
Plywood — it has excellent screw retention; MDF is moderate.
Is MDF water-resistant?
Standard MDF is not; use moisture-resistant MR-MDF in wet areas. Plywood is more stable.
Can you build in both?
Yes — we use MDF and plywood, or a mix, to suit each part of the cabinet.
