So I'm on my first replay that I've done of the original game in years. About eight hours in and I'm currently on Monstro. Just finished Agrabah. But a thought occurred to me once I moved onto Deep Jungle...Wonderland is much shorter than I remember it being. So with the point I am at now, I tried to figure which would be the shortest to longest levels in the game. 

 

Being that I can't really speak for certain level lengths (as it's been years since I've done them), I can't properly compile this list.

 

Any input? 

I think Olympus Coliseum would fall under longest world, as you have to do so much before you can actually seal the keyhole.

That's kinda tough. If I remember correctly, the Mysterious Tower from KHII was kinda short. Well, if that one even counts. For me, Hollow Bastion from KHI was pretty long. Mostly because I explored too much and got lost.

Olympus is longest, Wonderland is shortest.

When I first played Kingdom Hearts 1, Wonderland was so confusing and such a complicated maze that it felt long for me to finish that world, but when I became an ace at beating the games, the world seemed fairly short.  But I'll have to agree that Kingdom Hearts 1's Olympus Coliseum was long, so was Hollow Bastion and Agrabah.  In Kingdom Hearts 2, the worlds that felt longest for me were Hollow Bastion and Twilight Town.  As for shortest, I think Atlantica is really short since all you have to do is participate in musical numbers.  But yeah, it all comes to a matter of perspective when we think of how long or short some worlds are.

I totally cheated when I first played through the game....I had a guide book

Olympus Coliseum is the longest , I think ....

Olympus Coliseum is definitely the longest until you seal the keyhole, but I don't think that the length of the first visit is that long. 

Timeless River is preeeetty short if you think about it.

Guys I think he means more about KH1.

I would say Wonderland is the shortest it actually depends if you spend hours on searching.

Olympus Colleseum (excuse my spelling) Was long as heck. It took me days and days to complete it

 

In Re:coded story it wasn't short but it wasn't long (unless you decided to do the extra floors)

 

In Days story the missions were okay and Olympus Colleseum wasn't that long either. 

I always felt that Agrabah drags on forever on your first visit

 

Same goes for Hollow Bastion.

Olympus Coliseum was kind of the longest to me in KH2 but Hollow Bastion was so long to explore in the first kingdom hearts game.

If you are going by beating the world. 

 

Game                            Shortest                   Longest

 

KH1FM                          Wonderland              Hollow Bastion

KH2FM                          Pride Lands              Atlantica (Because of the stuff you need to get and do for it, i dont like it)

KH Re:CoM                    Traverse Town (Sora) Castle Oblivion (Sora)

KHBBSFM                     Keyblade Graveyard   Mirage Arena

KH Re:Coded (Basically just Re:CoM and KH1 mashed together so not doing it)

KH 358/2 Days (Can't really say... All are just as long as each other)

KH DDD                         Mysterious Tower       World that Never Was

   (Cant remember the real name for it)

It's been a while since I played KH1, but if I remember correctly Hollow Bastion took me a while to finish. The shortest world for me was probably Halloween Town.

Olympus Colleseum (excuse my spelling) Was long as heck. It took me days and days to complete it

 

In Re:coded story it wasn't short but it wasn't long (unless you decided to do the extra floors)

Wait! Extra floors?! S***, be right back!

Shortest - WonderlandLongest - Hollow Bastion

I agree with everyone who says Hollow Bastion is the longest. Every single time I entered that world, I felt like I was never going to leave! ( it's a beautifully designed castle though). However, I think for the shortest I would have to say Wonderland. (from KH 1)

I think either Hollow Bastion or End of the World would be longest.

I could list them, but we have to consider that it might be different for everyone

I feel Like Hollow Bastion was reaaaaaaaaally long. There were even chests I never got to reach.

The shortest was Halloween Town. The story in that one didn't last long at all. "Get us ingredients for a heart! Oh, Oogie stole it! Get it back!"

 

The longest was definitely Hollow Bastion, but that's not a bad thing. That world is definitely the best part of the game.

I think it's really just how you want to play it. If you want to explore the world's are much longer.

Monstro is pretty long, but that's because its so confusing

Olympus is longest and 100 acre woods is the shortest.

i think the longest world id the warld that never was.... i think
