Minecraft wiki entry for Map, associated text: When creating a new world in Bedrock Edition, the player can enable the "Starting Map" option to spawn with an empty locator map in the hotbar. If the world type is infinite or flat then zoom scale is 3⁄4 (1:8), but if the world type is old then zoom scale is 1⁄2 (1:4). The map is updated only while the player holds it.
