look at your transaction like this: https://blockchain.info/de/tx/1defc8711cfc0492f0bc84a56cf4c9e747fe785a6d23d1d4b914448086e0e034?show_adv=true

do you see on the right side those lines saying "Ausgabe" or in English output, those are outputs or in other words transactions you received. and when you are sending bitcoin you are in fact spending these.

when you spend multiple outputs your transaction size grows with the number of these you spend. you have 6 of them and you are creating 2 new outputs hence your transaction size is 961 bytes.

with current fee rules you need to pay 961 * 200 = 192,200 satoshi as fee

and this has nothing to do with blockchain.info wallet, it is how bitcoin have always worked. the only difference is the higher fees these days

oh, so even if I'd use another client for creating these transactions, that would be the same and it's not fault of blockchain.info

thanks for enlightening me!

But is there any tool to see the size of the transaction before sending it?
