<p>I am not sure which block it is, but you can see it on <a href="http://blockchain.info/charts/transaction-fees?timespan=all&amp;showDataPoints=false&amp;daysAverageString=1&amp;show_header=true&amp;scale=0&amp;address=" rel="nofollow">this graph</a> from blockchain.info. It was ~305 BTCs in transaction fees. The blockchain will not tell you why the transaction fees are so high. It is probably an accident or a joke.</p>

<p>I believe the largest size a block can be is measured in terms of bytes, and it is 1MB. So the largest transaction can be as large as 1MB of data will let it be.</p>

To this date (2024-05-31), the block with the highest transaction fees in bitcoins has been [409,008](https://mempool.space/block/0000000000000000042450ad2be4f2b6439ed39f70716a7575440d462cf165d9) which collected 291.533 ₿ in fees. This was caused by transaction [cc45…c570d](https://mempool.space/tx/cc455ae816e6cdafdb58d54e35d4f46d860047458eacf1c7405dc634631c570d) creating only one output worth 0.1 m₿ and failing to collect the change while using 14 inputs worth more than 291 ₿.

The block with the highest transaction fees in USD was [818,087](https://mempool.space/block/818087) collecting ‎85.216 ₿ in fees at that time worth about 3,189,221.5 USD, which again was caused presumably by someone not collecting their change output in transaction [b5a2…f9aa](https://mempool.space/tx/b5a2af5845a8d3796308ff9840e567b14cf6bb158ff26c999e6f9a1f5448f9aa).

Transactions are limited to 100,000 vbytes by standardness rules, and to slightly less than 1,000,000 vbytes by consensus rules, i.e. a whole block minus the at least [145 bytes](https://bitcoin.stackexchange.com/q/122951/5406) occupied by the coinbase transaction.

The largest transaction by [weight](https://bitcoin.stackexchange.com/q/54726/5406) is [bb4…3e08](https://mempool.space/tx/bb41a757f405890fb0f5856228e23b715702d714d59bf2b1feb70d8b2b4e3e08) with a weight of 3,998,628 WU in block 364,292.

The largest transaction by raw size is [ab03…2dad](https://mempool.space/tx/ab032d40dfea528836328b7cc1f958572da2affa22431e56ca65d4e73ce12dad) with a raw size of 3,992,821 bytes in block 839,842.
