“What size is a 1/4 inch plywood? How Thick Is 1/4 Plywood Actually?” non è ancora disponibile in Italiano

A sheet sold as 1/4 inch is usually about 7/32 inch thick after sanding, around 0.225 inches on the caliper. Nominal labels are sales names; thicker-than-one-inch specialty panels are the ones that more often match the stamped size. Use a caliper when the fit has to be exact for underlayment or drawer bottoms.

The usual sheet is 4 ft by 8 ft (48×96 in) with that thinner actual thickness. Softwood 4×8 panels in this class often weigh about 22 to 25 pounds, though hardwood faces and denser cores run heavier. Smaller cut panels are common for craft and cabinet shops that do not need a full sheet.

It fits cabinet backing, drawer bottoms, light underlayment under vinyl or laminate, wall paneling, furniture back panels, signs, and model work. The sheet stays light and easy to cut, which is why shops use it where strength is secondary to cover and finish. It is not the right pick for structural spans or concrete forms.

Very little compared with thicker panels. A small 12×36 inch piece at this thickness is only in the range of a few pounds per square foot under uniform load, while the same footprint in 3/4 inch can carry many times more. Treat quarter-inch stock as covering and backing, not as a shelf or floor skin.

Yes for cosmetic cover-ups over damaged plaster or tired wood ceilings, when local fire and building codes allow the assembly. The thin sheet hides cracks; it does not create a fire rating by itself. Confirm the wall or ceiling already met code before you skin it, and detail trim so casings sit flush on the new thickness.

Lauan (luan) sold as 1/4 inch typically lands near 0.22 inches actual thickness, close to other sanded quarter-inch sheets. Sheet footprints are often smaller retail blanks as well as full 4×8 stock, depending on the yard. Measure before you order if the face has to match an existing reveal.
