How do you change the resolution of your skin?

I’m trying to make a skin, and I don’t want the resolution to be 16x16. How do I change it??!!!

You need to use this editor: http://minecraft.novaskin.me/resourcepacks#default/textures/entity/steve.png

change the resolution on the right side panel

Yeah, but doesnt that mean that its a texture pack, and other people cant see your skin?

I’m not understanding your question.
https://minecraft.net/profile will only accept 64x64 (not 16x16) skins

Are you talking about block textures?
