Welcome to Workshop. I hope you find plenty of great advice as well as inspiration here from other community members.
I trust community members will be able to assist you with your door project. You might like to provide a little more detail about what you are after, perhaps even some photos. It would probably help Workshop members to provide more useful advice.
I look forward to reading more about your projects and plans. Thanks again for joining us.
This Bunnings how-to video suggests the top hinge should be about 200mm from the top of the door, while the bottom is 300mm from the bottom of the door.
If you need a middle hinge, it would be equally between the top and bottom hinges.
