18mm Particleboard Sheet Weight

4 × 8-foot sheets: 1–20 weight table

Totals multiply the unrounded sheet estimate. Values below are rounded to one decimal for readability and exclude packaging, pallets, coatings, and other cargo. Density ranges are model inputs, not guaranteed shipping-weight bounds.

How this estimate is calculated

The dimensions are 1.2192 m × 2.4384 m × 0.018000 m. Multiply them to obtain 0.053512151 m³. Multiplying by 640 kg/m³ gives 34.247777 kg per sheet, then divide by 0.45359237 for pounds. The area is 32 ft²; the representative weight per square foot is 2.4 lb/ft².

The selected density model is 640 kg/m³ with 600–680 kg/m³ reference variation, from Wood Panel Industries Federation: PanelGuide, Annex 2A. Representative density is the midpoint of the PanelGuide range; excludes laminate and melamine coatings. Check your supplier's exact panel weight when that information is available.

Compare another sheet size

At the same thickness and density, a 4 × 10-foot sheet is 94.4 lb (42.8 kg), 25% more than a 4 × 8. An exact 5 × 5-foot sheet is 59.0 lb (26.8 kg), with 25 rather than 32 square feet of area. Actual metric stock sizes can be slightly different. Use custom dimensions for the manufacturer's measurements.

Thickness and density scale weight linearly in this model. A nominal inch label is not automatically converted to a nearby metric product: 18 mm means 18 mm here. The example is a volume calculation, not a promise that this exact material, thickness, and sheet size are sold together.

Pickup payload reference

Illustrative reference values only — not your truck's rated capacity. Compare the representative sheet total with 1,000 / 1,500 / 2,000 lb. Passengers, tools, accessories, packaging, and other cargo also use payload. Check your vehicle's actual available payload and the high weight estimate.

Sheet total versus reference values
Reference	Used by sheets	Difference
1,000.0 lb	151.0%	Over by 510.1 lb
1,500.0 lb	100.7%	Over by 10.1 lb
2,000.0 lb	75.5%	489.9 lb before other loads

This reference comparison uses 20 sheets. The table above gives each smaller quantity. Check the high-density total, passengers, equipment, and your own vehicle documentation before loading.

Frequently asked questions

Does this include water or a surface finish?

No added moisture or coating allowance is applied. The source density is the reference model; rain-soaked panels, laminate, or a different wood core need product-specific information.

Why can my store list a different weight?

Nominal thickness, actual dimensions, core construction, and moisture can differ. Use the exact supplier's documented sheet mass when available instead of assuming this reference model matches that product.
