Is 23/32" the same as 3/4" plywood?
Yes. They are the same panel under two labels. 3/4" is the nominal (named) thickness and 23/32" is the actual milled thickness after sanding and finishing. The difference is about 1/32 of an inch, so the two are interchangeable for most uses.
What is the actual thickness of 3/4" plywood?
About 23/32", which is 0.71875" or roughly 18.26 mm. The full nominal 3/4" equals 19.05 mm, so the milled panel sits about 0.8 mm under its named size.
How many mm is 3/4" plywood?
Nominal 3/4" is 19.05 mm, but the actual milled panel measures about 18.26 mm (23/32"). Most suppliers round this to ~18 mm on metric spec sheets.
Does the 1/32" difference between 23/32" and 3/4" matter?
Not for subfloor, sheathing or general framing, where the two are interchangeable. It does matter for cabinet joinery, dado and rabbet fits, and flush transitions, where you should cut to the actual measured 23/32" thickness rather than the nominal name.
Is 23/32" plywood strong enough for a subfloor?
Generally yes. 23/32" (nominal 3/4") tongue-and-groove panels are the common residential subfloor choice over joists spaced 16 inches on centre. For wider 19.2" or 24" spacing, confirm the panel's span rating or step up a thickness, and always follow local building code.
How much does a 4x8 sheet of 23/32" plywood weigh?
A 4×8 sheet of 23/32" (3/4" nominal) plywood typically weighs about 50–70 lbs (23–32 kg), depending on core species and grade. Hardwood-cored panels sit at the heavier end. Always verify the manufacturer's stated weight for accurate freight planning.
