zdoom linedefs vertex sector limit

I'm starting to get into editing my own stuff and I know that zDoom has a limit to linedefs vertexes and sectors, and I plan on making a huge map but I don't know what the limits are to the above, anyone who can help me will be greatly appreciated

(sorry if this question sounds noobish)

If you use UDMF format there are no limits outside what fits into memory.

May I ask what makes the binary setup so different that it's unable to go past the short int limit?

The simple fact that you can't store values larger than 65535 in a short int. If you wanted to store larger values you'd need 3 or 4 bytes but then you'd have another map format already.
