A Nether Portal is an obsidian structure through which the player can travel between the Nether and the Overworld. They produce distinctive whimpering and crying noises and release purple dust-like particles. The Portal should be at least 4 blocks wide and 5 blocks high and is activated using a flint and steel. Players move the equivalent of 8 blocks on the Overworld by moving 1 block horizontally on the Nether.
The Nether is a frightening area with an exciting new collection of blocks and creatures, and visiting it is an important part of your Minecraft journey. Items such as blaze rods are obtained from the Nether which can then be used to craft other useful items. The portal was added to Minecraft as a part of the Halloween update in 2010.
Nether portal blocks produce distinctive whimpering and crying noises and release purple particles that resemble dust particles. These are the same purple particles produced by endermen, endermites, ender pearls, and the ender chest. A level 11 light is emitted by the portal blocks which is much dimmer than a torch and is not adequate to avoid mob spawning on top of a freestanding portal.
To make a Nether Portal in Minecraft you need 14 Obsidian blocks and 1 Flint and Steel. Obsidian block collection can be performed in many ways. If you have a diamond pickaxe, you can mine for blocks of obsidian. Obsidians can be found in mines along with pools of lava. Alternatively, you can make obsidian blocks by mixing lava and water. It is worth noting that obsidian will only be created if the water is poured onto the lava source.
The second item required is a flint and steel. This item doesn’t exist naturally and has to be crafted by mixing iron ingots with flint, which is obtained from mining gravel. Once you obtain flint and have iron ingots prepared from smelting iron ores, use the following recipe to make flint and steel.
The base of the Nether Portal should be 4 blocks wide, and the sides of the Nether Portal should be 5 blocks high resulting in a total of 14 obsidian blocks being used. More blocks can be used to make the portal larger, but 14 is the minimum number.
Next, you need to activate the Nether Portal. To do this, select the flint and steel in your Hotbar. Position your pointer on a bottom block of obsidian and then use the flint and steel. Once you have used the flint and steel on the portal frame, the center coordinates of the portal should glow and turn purple. This means that the Nether Portal is active and you can travel into the Nether.
Now that you have finished constructing it, all that’s left is to step into it. To use the Nether Portal, just walk through the purple area of the Nether Portal. You will be transported to the nether similar to the picture below:
You need to stand in the Nether Portal block for at least 4 seconds to be transported to another dimension. This is the case regardless of the dimension you are currently in. If you change your decision and don’t want to teleport, step out of the portal before it completes the animation, to abort this process. This privilege, however, isn’t available in creative mode as the player is transferred immediately as they step into the portal.
In case an active portal is already present in the other dimension, the player appears in that portal. Otherwise, at or near the corresponding coordinates, a new portal is created. A new portal can be created if a portal is deactivated and the corresponding portal is used in the other dimension before it is reactivated. Almost anything, including mobs (except the wither and ender dragon), thrown objects, and transport without passengers including boats, minecarts, and horses, can teleport through the portal. Storage minecarts and powered minecarts can also pass through.
It is possible to use this connecting portal to return to its corresponding Overworld portal. Within a certain vicinity, creating several portals in the Overworld would all result in the same portal in the Nether, and vice versa. Both linked portals will remain operational, but only the portal nearest to it will be controlled by the Nether Portal.
Since Minecraft worlds are 30 million blocks in each cardinal direction and contain an extreme number of chunks, the game loads only certain chunks to make the game playable. Loading starts when a chunk receives a ticket. All loaded chunks originate from the ticket.
Whenever you are teleported into a lower portal, the chunk gets a load ticket with a load rating of 30, which means that it is fully loaded and can process entities at the connected portal. This level of load often extends to neighboring chunks, but with each chunk, they get smaller. These chunks stay loaded for 15 seconds, but each time an entity travels through the portal, this timer gets refreshed. This can be used to load chunks indefinitely, producing a "chunk loader" creating a significant amount of latency and causing lag.
The Nether's horizontal coordinates and distances in a 1:8 ratio are relative to the Overworld. That is, players will move the equivalent of 8 blocks on the Overworld by moving 1 block horizontally on the Nether. However, the Y-axis remains unaffected by this conversion. Understanding this conversion can be extremely useful.
The game takes the coordinates when you use the portal. It then transforms these coordinates to destination coordinates: X- and Z-coordinate entries are multiplied if you are in the Nether or divided by 8 if you are in the Overworld, while the Y-coordinate is not modified.
If a candidate portal is located, then, as determined by the distance in the current coordinate system, the portal teleports the individual to the nearest one. A straight-line distance calculation is used in calculating between portals in the range and the shortest path, counting the Y-axis difference, is chosen.
If no portals exist in the search region, the game creates one by searching for the nearest appropriate spot to position a portal, within 16 blocks horizontally of the player's destination coordinates. When enough space is available, the orientation of the portal is random.
Once coordinates are selected, a portal is built at the target coordinates, including portal blocks, replacing everything in the way. If a portal is pushed into water or lava, the liquid automatically flows into the air blocks created, leaving no airspace for the player.

A. Nether portals can be of varying sizes with a minimum of 4×5, and a maximum of 23×23. So, it is up to you to make the choice of which size you find optimal.
A. The easiest way to do this is to remember the coordinates of the portal. Once you note down the coordinates and learn how to use them, navigating anywhere in Minecraft would become less of a hustle.
A. The Obsidian needed largely depends on the size of your portal since larger portals will require more obsidian blocks. The size of the portal we made was the smallest and required only 14 blocks. It is best to make a small portal to limit time spent on mining obsidian.
A. There can be several reasons, such as the portal not being big enough. It could also happen if the Nether isn’t available on your server, or it might just be a glitch and a simple restart to the game can solve your problem. Before jumping to any conclusions, make sure you eliminate any of the resolvable possibilities.
Nether portal: The specific formation of obsidian blocks that create the structure used to travel to the Nether.
End portal: The specific formation of 12 End Portal Frame blocks that create the structure used to travel to the End.
Exit portal: The exit portal from the End, framed in bedrock.
Congratulations! You just made a portal to the nether. Using this, you can travel to the Nether and back again any time you like. If you ever want to make potions, destroy some of the bosses, and have access to any other special items, visiting the Nether is required. The Nether can also be used to travel larger overworld distances in a small period of time.
