The plywood we buy in the US is a 4' x 8' sheet. Just out of curiosity, what size are they in countries that use the metric system?

In S.Africa 2440mm x 1220mm

That's almost exactly 4' x 8', just a little over but what do you center your wall studs in construction? We use 16" centers, 4 studs for a 4' wide sheet of plywood, drywall etc. but dividing 1220mm by 4 gives you 406.666666mm. The 2400mm x 1200mm that James quoted makes more sense for construction just because it divides evenly. Again, just curious, I know this thread was about the thickness but my mind kind of wanders a lot.

Sorry, 1220mm divided by 3, not 4. It's 4 studs but 3 spaces between them. I divided right just wrote it wrong!
