MDF and HDF are closely related dry-process fibreboards, usually distinguished by their specified density. Compare actual grades at the same thickness: density bands can overlap. At equal dimensions and density their calculated bare weights are equal; machining, finish and component performance still need their own checks.
For the available thicknesses, formats and cutting options, see Raw MDF, HDF and Hardboard. For a thin board with a different face/reverse construction, use the Hardboard, MDF and HDF comparison.
Compare the density at the thickness you are buying
MDF means medium-density fibreboard and HDF means high-density fibreboard. Both names describe wood-fibre panels, and their principal purchasing distinction is the specified density. Read that density together with the named product, thickness, supplied surface and intended component. The European Panel Federation's manufacturing guide explains the relationship between the MDF family and density-based product descriptions.
Our current Raw MDF and HDF catalogue schedules use the five thickness bands below. These figures apply to these two CUZI MDF products. Your quotation identifies the selected thickness, density target or range and supplied condition; a sample or batch measurement records the actual material assessed.
| Nominal thickness | CUZI MDF Raw MDF, kg/m³ | CUZI MDF HDF, kg/m³ | What the ranges show |
|---|---|---|---|
| 2–4 mm | 800–810 | 850–930 | Separate thin-board catalogue intervals |
| 5–8 mm | 780–800 | 830–890 | Separate intervals for this thickness band |
| 9–11 mm | 760–780 | 780–830 | The ranges meet at 780 kg/m³ |
| 12–18 mm | 680–750 | 730–780 | A shared interval of 730–750 kg/m³ |
| 19–35 mm | 650–680 | 680–730 | The ranges meet at 680 kg/m³ |
For an 18 mm comparison, a quoted MDF target and a quoted HDF target can sit within the shared 730–750 kg/m³ interval. Their actual density, properties, surface and component results establish the difference relevant to your order. For 3 mm material, our published HDF interval is higher than the Raw MDF interval. These are two different thickness-specific comparisons.
Use the Raw MDF product page and HDF product page for their full supply specifications. The schedule provides a numerical comparison; the colour, visible texture and product photograph describe appearance. Keep required performance alongside the density value so purchasing and production assess the same board.
Calculate sheet weight using equal dimensions
For a bare rectangular board, nominal mass in kilograms equals length in metres × width in metres × thickness in metres × density in kg/m³. Use matching dimensions for both products. The results below are calculated from our catalogue density ranges and a nominal 1220 × 2440 mm sheet; they are planning values for bare boards.
| Nominal thickness | Nominal bare volume, m³ | Raw MDF calculated mass, kg | HDF calculated mass, kg |
|---|---|---|---|
| 3 mm | 0.0089304 | 7.14–7.23 | 7.59–8.31 |
| 6 mm | 0.0178608 | 13.93–14.29 | 14.82–15.90 |
| 9 mm | 0.0267912 | 20.36–20.90 | 20.90–22.24 |
| 18 mm | 0.0535824 | 36.44–40.19 | 39.12–41.79 |
| 25 mm | 0.0744200 | 48.37–50.61 | 50.61–54.33 |
An 18 mm sheet at an assumed density of 740 kg/m³ gives 0.0535824 × 740 = 39.65 kg, rounded to two decimals. The same dimensions and density produce the same calculated bare mass for either selected board. The product name accompanies those inputs, while the calculation uses the inputs themselves.
For a finished door, add the actual facing, reverse, adhesive, edge material and fittings, and account for material removed through machining. For shipping, distinguish product net mass, packaging mass and gross cargo mass. Our density guide develops the calculations, and the packaging guide explains the different shipment quantities.
Understand what a sample density measurement tells you
Measured average density uses the sample's mass and actual volume. Record its identity, measured length, width and thickness, condition, method and tare-corrected mass. ISO 9427 specifies a method for determining the density of wood-based panels. Use the agreed current method and sampling plan for an order or laboratory comparison.
For arithmetic only, assume two bare rectangular samples each measure 200 × 280 × 18 mm, a volume of 0.001008 m³. The hypothetical readings below illustrate the calculation; they are assumed inputs, separate from CUZI MDF sample or batch test results.
| Assumed sample | Assumed dimensions, mm | Assumed tare-corrected mass | Calculated average density |
|---|---|---|---|
| A | 200 × 280 × 18 | 720 g, or 0.720 kg | 714.29 kg/m³ |
| B | 200 × 280 × 18 | 780 g, or 0.780 kg | 773.81 kg/m³ |
Actual results depend on the measured dimensions and condition of the tested pieces. A finished laminate sample includes layers with their own mass and volume, so its composite density answers a different question from the bare core's density. Identify the construction before comparing readings.
Average density describes the overall mass-to-volume relationship; a density profile describes variation through the thickness. The European Panel Federation's property guide assesses density separately from bending, internal bond, screw holding and swelling. Request the properties your component needs alongside the sample identity and thickness.
Our main photograph shows MDF and HDF samples on scales beside a thickness check. The density table and calculations above state their own inputs. A product or batch measurement report carries the actual readings, sampling and test method for the material being assessed.
Choose MDF or HDF around the furniture component
Start with the completed part. Raw MDF is a practical starting point for dry-interior furniture panels, painted faces and further decorative finishing. HDF provides our denser catalogue option for thin supported furniture parts and other components that benefit from the selected board's properties. Each choice becomes useful when the drawing, surface and assembly are known.
| Component or task | Product starting point | Selection details | Representative check |
|---|---|---|---|
| Painted or routed cabinet fronts | Raw, paint-grade or the specified MDF grade | Profile, remaining section, face, reverse, completed thickness and hinge layout | Coated first door with the intended hardware |
| Thin cabinet or wardrobe backs | Thin MDF, HDF or Hardboard | Groove or rebate, support, visible face, final thickness and fixing | Back fitted into the actual frame |
| Drawer bottoms and furniture liners | Thin MDF, HDF or Hardboard | Supported dimensions, contents, finished face and connection | Completed drawer with the agreed assessment |
| Cabinet sides and decorative panels | Raw or the selected faced MDF/HDF construction | Connectors, edges, decor, component IDs and finished fit | Matching adjoining parts and an assembled cabinet |
| Shelves and work surfaces | Board selected around the complete design | Span, support, intended load, section and required properties | Supported component and the design's loading assessment |
| Machined profiles and small parts | Actual MDF or HDF product at the required thickness | Tool access, holes, remaining webs, finish and handling | A trial containing the demanding features |
Thin MDF Board and Hardboard are separate product choices with their own supply specifications. Hardboard's actual face and reverse construction matters for supported backs and bottoms. The Hardboard, MDF and HDF comparison covers that wider decision.
For a mass-sensitive part, also consider Lightweight MDF using its selected reduced-density solid-board specification. For visible dark cut edges, Black MDF provides a through-coloured construction. These products have their own density and performance details; the Raw MDF schedule remains specific to Raw MDF.
Make the machining comparison representative
A matched machining trial helps your workshop judge the benefit of a board change. Use the same part drawing, supplied surface and intended finish, with the settings and tooling recorded for each trial. The actual material, tool and process determine workable settings and completed results.
- Include the part's longest cut, demanding routed profile, small holes, pockets and thin remaining sections.
- Identify the machine, tool geometry and condition, cutting strategy, feeds, spindle settings and hold-down arrangement used.
- Check dimensions from the specified datum, with appearance assessed on the intended visible face and finished edge.
- Record breakout, fuzzing, burnishing, chipping, profile continuity and any sanding or sealing work needed before finishing.
- Compare cycle time, tool condition, additional finishing work and accepted part counts over an agreed trial quantity.
- Complete the sample with the actual coating or facing, hardware and assembly so the results describe the part you will supply.
If cutting improves but an edge needs more preparation, both observations belong in the comparison. If a thinner part reaches its required fit and performance with a selected HDF construction, assess its completed dimensions, mass, cost and handling together. The trial gives your team a basis for an order-specific decision.
Our CNC MDF guide helps define profile and drawing inputs. The surface finishing guide connects machining with the remaining work. Send a drawing and the operations you want our factory to complete so the quotation describes the supplied stage clearly.
Check hardware and support in the complete assembly
Furniture hardware works with the material, part geometry and connection. Identify the actual screw, connector, hinge or support, then assess it at the intended position in the completed part. A board change can affect thickness fit, hole preparation, part weight and the material remaining around a fixing.
| Assembly detail | Information to keep with the board choice | Check on the representative part |
|---|---|---|
| Door hinges | Finished door dimensions and mass, hinge model, cup geometry and fixing pattern | Opening, alignment, clearance and the hardware manufacturer's applicable limits |
| Carcass connectors | Connector identity, datum, hole sizes, depth and edge distance | Joint fit, assembly sequence and the required joint assessment |
| Shelf supports | Span, support positions, contact detail and intended contents | Complete supported shelf under the design's agreed assessment |
| Back or drawer-bottom grooves | Finished panel thickness, groove dimensions and engagement | Fit through the full supported perimeter and fixing arrangement |
| Routed or perforated features | Remaining section, fastening zones and handling requirements | Local damage, connection fit and protection through assembly |
The European Panel Federation's screw guidance explains why screw type, insertion and pilot-hole preparation matter to a comparison. Apply current hardware instructions and the actual joint design to your parts. Our MDF drilling and hardware guide helps keep hole coordinates and component identity clear.
For furniture manufacturers, retain the checked first assembly with its drawings and material specification. For distributors, record which construction the product description and supporting data cover. This makes a repeat order easier to compare with the supplied board and the customer's actual use.
Specify the finish and completed thickness
Keep core thickness and completed component thickness as separate fields. A raw 18 mm board, an 18 mm core with facing layers and a coated drilled door describe different supplied constructions. The completed dimension must fit the groove, hinge, edge and adjoining part in your design.
For painting, request the required face and edge preparation, profile detail, sealer, primer and final coating system. Check a finished sample under the agreed lighting and viewing conditions. The MDF painting guide explains how the selected board and preparation connect with the finish you want.
For decorative supply, specify both faces, decor reference, texture, gloss, pattern direction, matching edge and any balancing construction. Melamine MDF, HPL MDF, Veneered MDF, PET Faced MDF and Acrylic Faced MDF have their own surface constructions. Confirm the selected core and overall product in the quotation.
For HPL MDF, our HPL face-sheet range is 0.5–1.2 mm. State the chosen face and reverse, adhesive construction and final panel requirement with the MDF core. A nominal sum of layer thicknesses helps describe the construction; inspection uses the agreed actual finished dimensions and method.
Compare finish results on the actual boards. The appearance of the supplied surface, adhesion, edge completion, required preparation and accepted physical reference make the purchasing decision more useful than density alone. Record each included operation so your workshop knows which work remains after delivery.
Match moisture, emissions and project requirements separately
Density identifies mass per volume. Moisture behaviour, emissions, fire classification and any structural or acoustic requirement each describe another part of the product or assembly. Put the destination, end use and required documents into the same inquiry as the board choice.
| Requirement | Information for your inquiry | What the selected supply needs to match |
|---|---|---|
| Protected dry-interior furniture | Room conditions, finish, cleaning and support | Board grade and completed component for that use |
| Humidity or incidental-moisture concern | Exposure, edges, holes, joints, ventilation and applicable test requirement | Named moisture grade and the complete protected construction |
| US or EU market documents | Destination, supplied product identity and applicable requirement | Relevant reports, declarations and shipment information for that product |
| Fire-specified interior project | Required classification, end use, core, facing and installation | Applicable document covering the identified complete construction |
| Structural or acoustic project | Responsible design, assembly and required assessment | Product properties and relevant results for the stated assembly |
Use Moisture Resistant MDF or High Moisture Resistant MDF when their specific grade matches the planned protected-interior use. An HDF name describes a density-related product choice; the moisture requirement still belongs in the specification. The moisture and conditioning guide helps plan receipt and workshop preparation.
Our US MDF document checklist and EU MDF purchasing guide organise destination-specific requests. For a fire requirement, use the Fire Rated MDF page and document checklist. We confirm the proposed product and applicable files with your actual order requirements.
Compare cost per accepted finished component
A useful cost comparison keeps the same completed part, accepted quantity and delivery basis. Include the board price, usable cutting yield, machining, finishing, hardware-related work, packaging and the transport or destination charges relevant to that quotation. Agree which charges are already included in a FOB or CIF offer before adding them to your comparison.
The arithmetic example below uses assumed quantities and cost. It shows how the denominator changes when you count accepted finished parts. It is separate from CUZI MDF pricing, an actual production yield or an expected rejection rate.
| Assumed comparison input | Quantity or calculation | Result |
|---|---|---|
| Order quantity | 500 components | 500 ordered parts |
| Accepted finished quantity | 480 components | 96% of the order quantity |
| Comparable total cost | US$1,200 | Assumed cost for the stated scope |
| Cost per ordered component | 1,200 ÷ 500 | US$2.40 |
| Cost per accepted finished component | 1,200 ÷ 480 | US$2.50 |
Run the same calculation with actual matched MDF and HDF trials. A higher board cost may be justified by the component result or reduced work; an established MDF construction may already provide the required result at an attractive complete cost. Your trial records and matched quotation give those conclusions their order-specific basis.
For freight planning, use actual bundle dimensions, net goods and gross cargo mass, load arrangement and receiving equipment. Calculated bare-sheet mass is a planning input. The quotation comparison guide and container-loading guide help align the commercial and logistics figures.
Compare samples, first parts and repeat supply
Move from an identified board sample to a representative completed part, then to the first assembly or delivery check. Each stage answers a different purchasing question. A small raw sample can show the supplied face and core; your demanding component shows machining, finishing and fit.
- Label the product, nominal thickness, density specification, sample identity and supplied condition.
- Use matching sample dimensions and the agreed measurement method for numerical comparisons.
- Keep the current part drawing, units, tolerances, datum and revision with the material request.
- Record the tooling, process, finish, hardware and support used to complete each trial.
- Assess the demanding features, appearance and complete assembly against the agreed requirements.
- Agree first-order inspection, any third-party inspection and the receiving records needed by your team.
- Retain the chosen material and finished sample references with the order so future changes can be checked clearly.
Our sample approval guide explains how board samples, decorative references and first components fit into purchasing. We support third-party inspection against the agreed order and inspection plan. For repeat supply, confirm drawing and sample revisions, part quantities and any changed finish or logistics requirement together.

MDF and HDF buying questions
What is the main difference between MDF and HDF?
Their principal catalogue distinction is specified density. Compare the named board at the same thickness, dimensions and supplied condition, then assess its required component properties. Our two products use thickness-specific density bands, including overlapping ranges at 12–18 mm.
Is HDF always heavier than MDF?
At equal volume, the higher actual density gives the higher bare-board mass. Our 12–18 mm catalogue ranges overlap at 730–750 kg/m³, so use the selected products' actual density inputs. Finished facings, machining and fittings also affect completed component weight.
Is HDF better for furniture backs and drawer bottoms?
HDF is one option for thin supported parts. Select the final thickness, face, groove or frame fit, support, fixing and intended use together. Compare Thin MDF and Hardboard where appropriate, and check the actual back or drawer in its complete assembly.
Does higher density mean stronger screw fixing?
Check the required screw withdrawal or joint performance with the actual product, thickness, screw, pilot hole and insertion arrangement. Average density is one material input. The representative completed connection and relevant product tests answer the fixing question.
Does HDF have moisture-resistant or fire-rated performance?
Those requirements follow the selected grade and applicable product or assembly documents. Specify the exposure or fire classification with the complete construction. We match the proposed board and available files to that request before order confirmation.
Can I compare MDF and HDF using sample weight?
Yes, when you record actual sample dimensions, bare or faced construction, condition, tare-corrected mass and the agreed method. Calculate density as mass divided by actual volume. Keep the identified results separate from nominal catalogue calculations and photographic displays.
Can HDF replace MDF at a thinner thickness?
A proposed thinner part needs its own design and trial. Check supported span, hardware fit, grooves, routing, finished dimensions and required properties. The selected complete component establishes the suitable thickness and the benefit of any substitution.
Which board should I choose for painting or CNC work?
Choose around the profile, remaining section, supplied surface and final finish. Raw or paint-grade MDF can be a practical starting point; selected HDF is assessed with the same demanding component and process records. Compare accepted results and complete production cost.
