| Feb 14, 2020 at 16:28 | comment | added | Jongware | There is nothing to calculate. There is no rhyme or reason to the length of x86/x64 opcodes. If you want the length of an opcode, you'll going to have to look up that specific opcode. Make sure to get any argument types correct; a simple jump jz can be from 2 to up to -- I think -- 5 bytes long. | |

| Feb 13, 2020 at 17:47 | comment | added | blabb | can you rephrase Your question ollydbg shows the opcodes for each instruction also it shows the address of current instruction and address of next instruction either count the opcode bytes or subtract current addr from next addr to get current instructions length | |
