How many different destinations can a single transaction have?

Question

I am building a web-app that needs to send money to different customer's addresses. I would like to minimize transaction costs and avoid unnecesary traffic, therefore I would like to pay all of them at the same time. How many different destinations can one single transaction have?

Cheers!

There isn't a maximum number of outputs but instead a maximum size of data in a block. So if there was just one transaction with a lot of outputs, the combined size would need to be below the block maximum of 500K.

I don't know the size of each transaction but you are talking thousands or tens of thousands of outputs before hitting these per-block limits.

Thank you Stephen. So, a transaction with 200 outputs would be okay, right? :-) – flaab Nov 13 '12 at 16:29
That's no problem at all. I expect such a transaction to be around 7 KiB, unless you need a large amount of inputs. – Pieter Wuille Nov 13 '12 at 19:05
