MDF or MDP? The difference that defines the quality of your custom-made furniture
Marcato Móveis · Fine Woodworking · Technical Guide
Almost every custom furniture quote mentions MDF or MDP. Few salespeople explain the difference. And most buyers only discover it makes a difference after the furniture is already installed.
What is MDF
MDF — Medium Density Fiberboard — is a board of wood fibers pressed with resin. Its uniform density makes MDF the ideal material for machining and routing: it accepts precise cuts, rounded edges, profiles, and carved details without chipping. This is why MDF is the correct material for doors and drawer fronts.
What is MDP
MDP — Medium Density Particleboard — is a board of pressed wood particles. Less dense than MDF, MDP is lighter, more dimensionally stable, and significantly more resistant to humidity and temperature variation. This is why MDP is the correct material for the furniture structure: side panels, shelves, back panels, and dividers.
The correct combination: MDF for doors, MDP for the structure
| Furniture Part | Correct Material | Why |
|---|---|---|
| Doors and drawer fronts | 20mm MDF | Smooth surface, accepts machining and perfect painting |
| Side panels | 18mm MDP (kitchen/bathroom) or 25mm (bedroom) | Dimensional stability, weight resistance |
| Shelves | 25mm MDP | Rigidity to support load without warping |
| Back panel | 15mm MDP | Lightness and sufficient stability for the function |
These material criteria are the basis of what defines fine woodworking — the set of technical decisions that separate furniture that lasts decades from furniture that fails in years.
Thicknesses matter as much as the material
Low-cost cabinetmakers cut thicknesses to reduce the price. For kitchens and bathrooms: 20mm MDF doors, 18mm MDP side panels, 25mm MDP shelves, and 15mm MDP back panels. For bedrooms and closets, the side panels go up to 25mm MDP — a premium thickness that ensures stability even in taller modules.
Marcato Móveis Standard
All custom-made Marcato furniture uses Duratex or Arauco panels, with 20mm MDF doors and MDP structures in the correct thicknesses for each environment — 18mm in the kitchen and bathroom, 25mm in the bedroom. Specified in the contract, non-negotiable.
