Differences Between MDF Vs. HDF

Whether to use MDF vs HDF is a question that many building professionals and DIYers have. These engineered wood products stand out as effective building materials because of their versatility, durability, and cost-effectiveness. But medium-density fiberboard (MDF) and high-density fiberboard (HDF), despite their similarities, have distinct characteristics that set each one apart. Exploring both the similarities and the differences between the materials will allow you to make a more informed decision about which material best suits the specific needs of your project.

Similarities and Differences Between MDF Vs. HDF

MDF vs HDF: Similarities and Differences

Consider the qualities that MDF and HDF share and the ones that make them distinct to choose the best fiberboard for your project.


MDF and HDF share many of the same qualities due to the similarities in their manufacturing process and their base materials. Some key similarities include:

  • Engineered wood products – Both MDF and HDF are manufactured using wood fibers gained from hardwood or softwood residuals. Manufacturers combine these wood fibers with resin binders and compress them into boards under high pressure and heat.
  • Composite materials – MDF and HDF are composite materials. They are composed of both natural and synthetic materials. This composition gives MDF and HDF consistent properties and characteristics.
  • Versatility – Both MDF and HDF are highly versatile and fit a range of needs for woodworking and interior design. You can cut, shape, and machine them to fit specific applications.
  • Dimensional stability – MDF and HDF have high dimensional stability, meaning that they are less prone to shrinkage and warping than natural wood. This quality makes them ideal for projects like cabinets where dimensional stability is a necessity.
  • Smooth surface – The smooth surface of MDF and HDF makes them ideal for projects where you want a flawless finish. You can customize this smooth surface in a variety of ways including painting, laminates, or installing veneer with decorative finishes.
  • Eco-friendly components – MDF and HDF have certain environmental benefits including that they are composed of waste materials. They take the place of solid wood in many applications and reduce the need for new timber products.
  • Cost-effective choice – The cost for MDF and HDF are both less compared to solid wood and plywood products.
  • Pest resistance – Wood fibers are integral to the construction of both MDF and HDF, so they are both susceptible to the infestation of wood pests like termites. It is vital to protect both materials with proper sealing techniques.
  • VOC emissions – Standard MDF and HDF contain synthetic glues which emit VOC gasses over time, though the risk to your health is low, especially once the fiberboard has been sealed with paint or something else. You can find natural resin options for both MDF and HDF which do not contain VOCs.
  • Fire resistance – MDF and HDF are combustible materials because of their high wood content. Neither are considered fire-resistant materials.


There are notable differences between MDF and HDF. Here are some of the key distinctions between the materials:

  • Density – The most significant difference between MDF and HDF is in their densities. HDF has a higher density in comparison to MDF because it is manufactured with higher pressure and with much finer wood fibers. HDF has a density of 50 to 65 lbs/ftΒ³ (800 to 1,040 kg/mΒ³) compared to the density of MDF, which is 30 to 50 lbs/ftΒ³ (480 to 800 kg/mΒ³).
  • Strength and durability – Due to its density, HDF has more strength and durability than MDF. It is much less prone to denting and scratching, so it is better for furniture, flooring, and other applications that receive heavy wear. HDF also has a higher tensile strength, meaning that it holds screws better without splitting or breaking.
  • Weight – HDF is about 20%-30% heavier than MDF due to its high density. This extra weight can be advantageous for some projects where structural stability is vital. But the heavy weight of HDF can cause challenges in handling and installation.
  • Moisture resistance – HDF offers better moisture resistance than MDF. While neither material is waterproof, HDF can withstand more humidity and moisture.
  • Cost – Both MDF and HDF are cost-effective choices compared to solid wood, but HDF is more expensive than MDF because of its density and enhanced characteristics.
  • Machinability – MDF and HDF machine well, but HDF may require more powerful machinery because of its higher density.
  • Carbon footprint – HDF has a longer lifespan than MDF and produces less waste during manufacturing. This reduces the overall carbon footprint of HDF which is lower than the carbon footprint of MDF.

When Should I Use MDF vs HDF?

The choice between MDF and HDF depends on the specific needs of your project. Here are some guidelines to help you choose between them.


  • General-purpose projects – Use MDF for general-purpose projects where your materials don’t need to be extra strong, durable, or moisture-resistant. MDF is ideal for most DIY and small interior design projects.
  • Intricate or curved designs – The lower density of MDF means that it is easier to machine and cut than HDF. Therefore, for certain projects like cabinets, interior molding, or craft projects, using MDF is advantageous.
  • Cost – MDF is less expensive in comparison to HDF, so if cost is a factor in your project, use MDF if it fulfills your project’s requirements.

Best Use Projects for MDF: Furniture, cabinets, wall panels, doors, shelves, interior molding


  • Heavy wear projects – Use HDF if your project will be subjected to heavy wear and use. Some of these projects include flooring and heavy-use furniture.
  • Moisture resistance – Use HDF products in areas like bathrooms and basements that require higher levels of moisture resistance.
  • Weight is not a factor – HDF is heavier, so handling and transporting it can be more difficult. Use HDF if weight is not a concern.
  • High structural integrity – If your project requires it to resist heavy loads, use HDF because of its greater strength and ability to resist tension forces.

Best Use Projects for HDF: Flooring, core material for doors, heavy-use furniture, wall panels for areas of high impact, structural components, heavy-duty shelving, workbenches
