Introduction: The Portal Door

Picture of The Portal Door

I will show you how to put portals on your door or wall.

Step 1: The Template

Picture of The Template

You will need the template somewhere under this text. It is very big (7500 x 500 pixels), because it has to be printed on a very big paper (makes sense, huh?).

What it contains:
- 2 portals in orange and blue. They have a transparent background that has to be replaced with the pictures from step 2.

- 2 Portal logos. One is bigger than the other one, I cut the letters out and glued them under and over the portals, this looks a lot more professional ;)

- A nice picture of my favorite cube, the Companion one! I just don't like the feeling of wasting space, cut it out or throw it away, I don't mind.

The template is available for a white and a (dark) brown background, because the boundary of the portals are blurred. The picture down there shows what it looks like, but please don't use this, because it is way too small.

Here you can get the template in both colors:

Step 2: The Pictures

Picture of The Pictures

Make 2 pictures, from the 2 views you will hang your portals, for example like this one. If you can, go a bit behind the point where the portal will be, so you can get more of the room behind it on the photo (This does only work with doors, don't try to take a photo through the wall ;)).

Step 3: The Marriage

...of the photos with the template. Put them under the portals (Does that work in Paint? Guess not, if you can, use Paint Shop, Photo Shop, Gimp or something else) and resize them that they fit. Therefore, you will have to create new layers under the portal-layer where you can put your photos. You may have to erase some parts of one picture, so that it doesn't cover the other one. Save this as a png or something that is not jpeg and bmp (Or you can spend years while uploading).

This is what it should look like:

Step 4: The Poster

Picture of The Poster

You will have to get this picture on a poster, either you print it yourself or you let it print (online is cheap and easy). You wouldn't care about where I bought my poster, because I live in Germany ;)
I ordered the size 150 x 100 cm, so the portals are ~100 x 50 cm big (In fact it's a bit lower but wider)
That should cost about 30 - 40 $ (please mind the forwarding charges).

Step 5: The Time Until Your Poster Arrives

You can play Minesweeper or drink some coffee until your poster arrives.

Step 6: The Physical Work

After you are happy about your portals having arrived, you have to cut them out. Don't cut away too much, otherwise you have a hard transition that doesn't look nice.

Attach your portals flat on the surface you want to be portaled, that works best when you use 5 - 10 pieces of double-sided tape, 2 of them in the middle and the rest close to the boundary. First, only use the 2 pieces of tape on the top to fix it and see if it hangs correctly. Then you can fix it with the other tapes.

Step 7: The Finishing Touch

You can add the Portal-Logo if the portal looks too paltry. Just cut the letters out and attach them above or under the portal.

If you also want the GLaDOS-camera on the photo, this is just a papercraft and can be downloaded here:
I assambled it with 155% of the size.

And now you're done! Have fun with your portals.

SkyWolf03 (author)2015-06-02

Can you reupload the template? It keeps getting broken :/

THEJJRAT (author)2015-05-15

Be cooler if you could cut a hole out of the door. It would make it more realistic.

theawesomness1000 (author)2014-05-29

Hey! I would just put a hole in my door and paint blue and orange around it!!

What size paper do you recommend? (author)porkchoppiggy2012-10-05

I used A0, but it could be bigger.

porkchoppiggy (author)2012-10-02

could you also send it to me? My email is (author)porkchoppiggy2012-10-03

The link in the description does actually work, it is just linked wrong and I can't change it at the moment.

stratisfire (author)2012-04-22

i think it would be cool if you could somehow display video on the "portals" so you could have on upstairs and one downstairs and be able to see what is coming from the other camera.

can you send me the template my Email is:

erowe (author)2011-10-28

This is amazing. Could you upload the template again?

batonas (author)2011-10-28

great idea but you should cut a hole in the door for more realism :D

jjunod1 (author)2011-08-06

What I did was sorta a play-off of think geeks portal shirt (here) and i kinda made a frame by printing it twice then i put a screen in them then sealed it

andyxxpanda (author)2011-07-24

it would be cooler if you hung one on the oposite side of the room

championx5 (author)2011-07-20

only thing fail about this is if u take the picture during theday then itll look fake at night

freakyqwerty (author)championx52011-07-22

Need to have part of the door as glass...

UpgradeTech (author)2011-02-25

I'm sorry, but I've tried all the links in the comments and I cannot find the template anywhere. Could you repost it? (author)UpgradeTech2011-03-02

I hope this one works

JohnRulz (author)kamibox.de2011-07-11

Not working either. Try a different file sharing site, or set up a torrent. Torrents are more reliable than file sharing sites, if you can get enough seeders. You could also set up something on an image sharing site. I am not sure how large the file is, but Flickr has the larges limit (to my knowledge) of 10 mb

tinker234 (author)2011-06-29

hey could i add a projecter and 2 cameras to make a projected image of each side if they change also be cool to have a hole so you could walk thourgh

tinker234 (author)2011-06-27

wow hey could cut a hole in the door to go thourgh

blanchae (author)2011-06-23

I wonder if it would better using a mirror instead of a picture?

ralphkidsguns (author)2011-06-23

this was a triumph.
i'm making a note here, huge success!

jarnold3 (author)2011-06-23

This was a triumph...

Jo-dan (author)2011-06-18

could i make it bigger so that each portal can cover more of the door?

reddog92396 (author)2011-06-11

Hah ! Nice! You should have just cut a hole in the door! LOL that would have been funny I can see people's reactions

"Woah an actual portal!"

demonkiller111 (author)2010-06-30

You know it might be easier to get a door with a round window in it and just paint the portal around it.

The_Auror (author)demonkiller1112010-07-01

What's the point of having a door if anyone could see through it then? Yeah, I tought so...

demonkiller111 (author)The_Auror2010-07-01

hmm you do have a point there, :s

ok, i will talk about the portal on the outside, so the cameras see what is in the room ad the projector projects the image onto the door.
you doo the same with the other side

Just make it so that it can be closed.

you could make an iris like on cameras

nclarke (author)2011-05-28

Should I use Paint Shop, or Paint Shop? Which do you think would be easier?

Higley1089 (author)2011-05-25

I made a much smaller version using a regular printer and a camera.
(i needed to make a small one anyway. My door isnt Flat)

STICKDUDESHOOTER (author)2011-04-21

How do you do that im noob with photoshop

you simply take the two photos, drag one onto the other, and resize, or remove any nonwanted areas.

asarris (author)2011-05-12

I like it just cant find paper that big, i took my dads old projector and a web cam and hooked it up together. Then i put one of your portal image on the other side and i had a portal that i can outside and they think its fake.
