size= is key size, NOT keyfile size.
It seems systemd's crypttab currently has no means of specifying keyfile size, so it will always try to read the maximum (up to 8MB according to cryptsetup --help).
And what is the difference between the keyfile size and the key size?
According to crypttab(5): "size= Specifies the key size in bits; see cryptsetup(8) for possible values and the default value of this option." As it is custom in cryptography, key sizes are given in bits, like RSA 4096 which means the key is 512 bytes long. If your former size argument was given in bytes, convert that number to bits and try again.
