The easiest way to determine an honest weight of a 4' x 8' sheet of plywood? 20-25 pounds per 1/4" of thickness. 3 pounds per square foot per inch of thickness according to APA Plywood Design Specification.

4x8
A half-inch 4'x8' sheet of plywood typically weighs between 30 to 40 pounds, depending on the type of plywood and its moisture content. Standard plywood, such as fir or pine, tends to be on the lighter end, while heavier types, like oak, may weigh more. Always check the manufacturer's specifications for the most accurate weight.
It depends on how big a sheet of plywood you are talking about.
The thickest plywood sheet available for purchase is typically 1 1/8 inches thick.
3,600 square inches.
20-25 pounds per sheet, per 1/4" of thickness. In other words, about 25 pounds for a sheet of 1/4, about 50 pounds for a sheet of 1/2.
A 3x6 plywood sheet typically weighs around 25-30 pounds, depending on the thickness and type of plywood.
The weight of .75 inch plywood varies based on the type of wood used. On average, a sheet of .75 inch softwood plywood weighs about 61 pounds, while a sheet of .75 inch hardwood plywood weighs around 75 pounds.
The amount of weight a half-inch sheet of plywood can hold will depend on the grade and type of plywood, as well as the size of the sheet and how the weight is distributed. As a general guideline, a half-inch sheet of plywood can typically hold between 40-60 pounds per square foot when evenly distributed.
A 4x8 foot sheet of 18mm MDO Plywood typically weighs around 80-85 pounds.
About 50 pounds
when asking this question you first need to take into account that plywood comes in different thicknesses therefore weight per particualr thickness of sheet plywood will vary-- in my opinion/ without fact and research / a sheet of 1/2 inch plywood may way about 16 lbs. while a 3/4 inch plywood sheet may way 70 lbs.
The weight of lauan plywood can vary depending on its thickness and size. On average, a 4'x8' sheet of 1/4" lauan plywood weighs around 22-26 pounds, while a 4'x8' sheet of 3/4" lauan plywood can weigh approximately 60-70 pounds.
1/3 square foot.
The weight of luan plywood can vary depending on the thickness and quality of the wood. On average, 1/4-inch luan plywood weighs around 22-24 pounds per sheet, while 1/8-inch luan plywood weighs around 11-13 pounds per sheet.
