Help Needed. MK4 Scale

[NobleSeven20]

First time post here and I am in need of assistance for my first costume. I plan to make the Halo Wars MK4 but I'm running into a scaling problem. I have Pepakura Designer but am not familiar enough with its functions to know how to scale it to my proportions. I'm around the 180-185cm in height so if anyone can do the math I'd really appreciate it.

If I've garbled this up let me know and I'll rephrase it better.

Hey NobleSeven, first of all - welcome to the 405th! Unfortunately scaling patterns is a little harder than just adjusting for height - there are many factors to consider, especially since the game armour is designed for someone with unrealistic proportions. If you want to invest in a program for cosplay, check out Armorsmith - it'll allow you to take 3D models or pepakura patterns and scale them on an avatar tailor adjusted to you, then save them to print/3d print.

I haven't used this guide before, but here's one on scaling for Pepakura - hopefully it'll be of some use to you.
Good luck!
