blockchain.info huge transactions

[iensu]

I realized that blockchain.info wallets are creating huge transaction sizes due to splitting one transaction and then merge it into one 
It's causing expensive transaction fees!

why is that so and how can I prevent this stupid "feature"?
Is there any setting on the blockchain.info wallet?

example tx: https://blockchain.info/de/tx/1defc8711cfc0492f0bc84a56cf4c9e747fe785a6d23d1d4b914448086e0e034

I just had to use btc.com tx accelerator and gave those chinese 11 dollars...

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?

that is correct.
although different wallets may use different ways of suggesting appropriate fee but they usually are in the same range. you can also always use this website for more information: https://bitcoinfees.21.co/

your wallet should do that for you. it automatically makes a guess of transaction size then makes an estimate of current fee and gives you final result to make it easy for the end user.
although they usually have an advance section to show you the size and fee in satoshi/byte
i know electrum allows you to set it with an slider and if you preview the transaction before signing it shows you size of the transaction also.

yeah, blockchain.info guesses to small fees, if you want your tx be confirmed in the next blocks...

so i'll give electrum a try for the next time. thanks a lot!

You can click on advanced send option on left hand buttom in send bitcoin window where you can adjust fees and it will show you estimated time (blocks) of confirmation but better you set enough fees where it will show 1 blocks.

Op, if you are sending large sized transaction (merged with many outputs) then the best option, if you don't want to pay ridiculous 240 sat/byte fee,
might be use 0.0001 BTC/KB fee and then push it thought transaction accelerator - https://www.viabtc.com/tools/txaccelerator/
Or if you have no problem with it - using online wallet which pays fees for you - Xapo.
