Where to buy those good chess sets?

You know, the ones they use at the big tournaments, the wooden ones with light brown and ivory colors board and pieces that match nicely? What is that board called? And doesn’t it have some electronic sensors as well? Not that I need that feature. Just want a large regulation size beautiful board and pieces.

I believe you're talking about the DGT boards: http://www.digitalgametechnology.com/index.php/products/electronic-boards

You can purchase nice wooden boards and pieces suitable for tournaments virtually everywhere. But if you look for something extraordinarily beautiful:

My recommendation, my most beautiful chess set.

there is also square off which is pretty interesting

I don't know if this is the best place to buy it, but you can find the World Championship set (without the DGT sensors, etc.) here: shop.worldchess.com/shop/official-world-chess-set

@Sarg0n wish you didn't share that website. Now I will want to buy all of those lol

Wow, many nice choices...

When OTB tournaments are held, what are the board dimensions? In inches or centimeters.

My standard green & white, roll out - tournament board... is 20"x20" :]

20" or 50cm.
