Trick question! A single sheet of OSB weighs about 1.5 lbs per sf or 47 lbs, assuing you are asking about 7/16 thick, not 716.One sheet of plywood weighs a bit more.he weight of treated plywood will depend on the size of the  plywood. A 4 x 8 1/2 inch piece of treated plywood will weigh an  estimated 50 pounds.
EXACT dimensions of 4x8 sheet? Brian in Sandusky, OH. >If I'm not mistaken, a 4x8 sheet of MDF, plywood, etc is actually 97 x 49, right? (long story, but my shop space has been VERY small for about a year now. It's been a while since I bought a full size sheet of plywood, I'm embarrassed to say...) The reason that I ask is that I'm finally breaking ground on a new shop soon, and I just sold my truck (gas prices, insurance, etc.) and I'm buying a trailer to put behind my car. One trailer that I'm looking is has EXACTLY 96 of internal length. No more. A 97 sheet will not fit.
