Creating a new world and making it an Old World limits that specific world size to 256x256. Going into settings>video and activating "Limit World Size" will make all newly created worlds as Old Worlds. This is not what the OP is asking for.
"In the Xbox 360 Edition, PlayStation 3 Edition, PlayStation Vita Edition, and Wii U Edition, the Overworld is limited to 864×864 blocks. Additionally, in the Xbox One Edition, PlayStation 4 Edition and Nintendo Switch Edition, the player is able to further select the size of their worlds, from Small (1024×1024), Medium (3072×3072), and Large (5120×5120, Switch excluded). The edges of these worlds are surrounded by an endless sea of water, preceded by an invisible barrier." -- Source
There was mention of adding the Small, Medium, Large sizes to MCPE by Tommaso. It just hasn't been implemented yet.
I don't like a infinite world. I prefer something that is smaller and manageable because I plan to develop most of it.
I heard the Xbox One version can do Small, Medium and Large ... but I am guessing the Win 10 edition is a lot different?
Since I already own the Wii U, PE (phone) and PC version, I really don't want to spend money on another if it can't do what I want.
Is the Xbox One version the way to go then? My only worry about the render/view distance on those.
Thanks.
Change the world type from "Infinite" to "old" and you'll have what you're looking for.
Yes but Old is only 1 map space right? I find that far to small. I really want Large.
I have an option on mine that says limit world size... I have never tried it tho

I think that just makes a old world type. Doesn't look like the Win 10 edition can do Small, Medium or Large. Pitty
