Bitcoin transactions are not stored on blockchain.info, they are stored on the Bitcoin blockchain. The blockchain is a public ledger of all Bitcoin transactions. blockchain.info is a website that provides an easy-to-use interface for accessing the Bitcoin blockchain.
When you send a Bitcoin transaction, it is broadcast to the network and stored in the blockchain. The transaction will have a certain size, which is measured in bytes. The size of a transaction depends on the number of inputs and outputs, and the size of the script used to create the transaction.
A typical Bitcoin transaction will have one input and two outputs. The input is the address from which you are sending the Bitcoins, and the outputs are the addresses to which you are sending the Bitcoins. The size of the input will be about 34 bytes, and the size of the output will be about 33 bytes. The size of the script will be about 10 bytes. So, a typical Bitcoin transaction will be about 77 bytes.
The size of the transaction will also depend on the number of signatures that are required. If you are sending Bitcoins from a multisig address, then the transaction will be larger because it will need to include multiple signatures.
The size of the transaction will also affect the fee that you pay. The fee is calculated based on the size of the transaction in bytes. So, a larger transaction will cost more to send.
