What is 4x8 Sheet?

A 4x8 sheet is the most common panel size in North American woodworking and construction. The dimensions are 4 feet wide by 8 feet long (48 x 96 inches, or 1220 x 2440 mm), covering 32 square feet per sheet.

Why 4x8 is the standard. The 4-foot width fits between wall studs on 16-inch centers (three stud bays). The 8-foot length matches standard wall height. These dimensions make the 4x8 sheet the most efficient panel for sheathing, subflooring, and wall paneling.

Available materials in 4x8: - Plywood: CDX, sanded pine, birch, Baltic birch (note: Baltic birch also comes in 5x5 ft) - MDF: standard and moisture-resistant grades - OSB: oriented strand board for sheathing - Melamine: pre-finished particleboard for cabinets - Hardboard: smooth-faced panels for cabinet backs

Other standard sizes. Not all sheet goods come in 4x8. 5 x 5 ft (1525 x 1525 mm) is standard for Baltic birch. 4 x 10 ft and 4 x 12 ft are available for tall walls. European panels use 2500 x 1250 mm (slightly larger than 4x8). Half sheets at 4 x 4 ft and project panels at 2 x 4 ft are sold at home centers.

Weight. A 3/4-inch 4x8 sheet of plywood weighs about 60 lbs (27 kg). MDF is heavier at 96 lbs (44 kg) for the same size. Plan your transport and handling accordingly.

In the cut list workflow, the 4x8 sheet is the default stock size for sheet optimization. SmartCutList lets you set custom stock dimensions, so you can also optimize for 5x5 Baltic birch or European-size panels.
