[Request] Help me find a good ratio for these 4 spices

I want to make a good spice blend to keep in my kitchen, to add to various food items. I know what 4 flavors I want, I just don't know what ratio these spices need to be in to be balanced. Some are stronger than others, I know.

1. Smoked paprika

2. Ground mustard

3. Cayenne pepper

4. Garlic powder

Ideally I'd like the smoked paprika to be the dominant flavor here. And I know garlic powder is very strong. But other than that I'm unsure what ratio I should combine them in.

Any ideas?
