=Backdrop for Underworld= First off, I love this article. Secondly, could someone add a description for the Underworld's backdrop? I haven't been there yet, lols. --FungusTrooper 20:37, 19 May 2011 (UTC)
 * Done. --Eplemosen 12:30, 23 May 2011 (UTC)

=Depth vs map size= Would it be possible to take map size into account when describing how deep a particular layer generally appears at? From the map size page it appears there are 3 fixed map sizes and they are conveniently sized in a 1.0x, 1.5x, 2.0x ratio. So for example something that appears around -1,000ft deep in a small map would be around -1,500ft deep in a medium map and -2,000ft deep in a large map. Or have I got it wrong? In any case, I just reached the underworld in my small map (my very first game) and it's very much less than the -3,100ft mark mentioned here -- so it's not hard to guess that the figures currently listed here are based on a large map's measurements - Spinfx 07:29, 14 July 2011 (UTC)
 * Huh, this still hasn't been fixed yet? I only have a medium world right now and can't take the measurements for the others. Come on guys, I'm sure you multiplayer people have dozens of worlds you've already drilled all the way through. - Spinfx 06:42, 30 December 2011 (UTC)
 * Measurements for a Medium sized world:
 * Cavern Layer: 508ft
 * The Underworld: 2368ft

gemstone in cavern layer go discovered first time during 1.0.5
before 1.0.5 what was behind all the helivators and dense walls of a cavern were unknown, and people were likeley to run past ores and gemstones all the time: before 1.0.5's spelunker potion the dee cavern layers were thought to have the same rarity of gemstones and gold as the layer above it: 1.0.5's potions arent just potions you can craft: but are next step developer technology for the wiki, infact it was thought gemstones were the rarest thing you could find in the underground (second best to gold pre-generation of world, and cobwebs, pre-generation of the world which must be "hunted" for) can you see that the potions that help players out, can aso help this wiki improve?

map size versus map depth (RE)
on a large map, i didnt have a depth meter but bear with me: TOOK AN AGONIZING TIME to get to the nether, but upon generation it had a pre-opened up passage within the caverns i was mining down into, with also a steep drop and a hill which i could use to store my cash, etc., nether enemies however could spawn on a spire of ash and hellstone reaching outside the nether. on a small map however i discovered skeletons and some gold in a few seconds flat compared to a large map where i had t agonizingly hunt and dig down, i dont have a depth meter becuase it doesnt add any bonuses like +1def (put it in storage) but it seemed like digging to the nether on a small map was childs play: a deadly childs play that is. while on a large map: plain agonizing, so yes map size can DEFINATLEY affect map depth, and it is certain that biomes and layers are affected by map size, and to new players who want to beat the game fast: large = lotsa resoruces, deeper layers. small maps = less threat, resources more packed together, but less depposits / air pockets (which means less exploring around, good for those who dont have a lucky horse shoe yet). medium = soso, take your chances.

Bottom
What is at the bottom of th world that keeps you from going down any further? Is there a bedrock like block that is unbreakable? Do you fall and suffer a horrible death if you go past the bottom? Is there an invisible wall? Do you just respawn at your house? WHAT HAPPENS!
 * Same thing happens as when you reach the top or sides of the world: the screen stops scrolling and you can't leave the sides of the screen. --0icke0 (talk) 10:32, 10 July 2013 (UTC)

Surface Layer
Hello, fellow Terraria wiki editors, I just noticed that the different layers are summed up on this page, but some layers also have extra pages. Should the remaining layer pages be created or should the layer pages that are already there be merged with the Layers page? Terrariapc1 (talk) 14:40, 2 April 2015 (UTC)
 * From the looks of it, I don't see any pages that need to be added or merged. The surface biomes are better off separated on their own pages, and I really don't see a need to create a Surface Layer page, as it likely wouldn't go into much more depth than the heading on this page.

 * It's worth noting that there was a surface page once; it stayed a stub until being made into a redirect due to not having enough content to sustain itself. Gearzein (talk) 19:10, 2 April 2015 (UTC)

=Depth Figures Are Inconsistent= The current page shows a table for Underground layer depth as -1351 to -1655 (small world), -2243 to -2562 (medium world), and -3277 to -3588 (large world). But then the "Underworld" section asserts that "Usually this layer begins at the -3000ft mark and expands downward to the bottom of the map." The table appears to be the more accurate, due to its precision, so I will remove / revise the more vague assertion in the Underground section, but if anyone has a source for the exact numbers,, please include the correct data and cite the source. (Should be based on the game code, or other direct evidence, please.) Memetics (talk) 06:59, 25 August 2019 (UTC)


 * In fact, it's more inconsistent than that, because in no case does adding up the table's layer numbers match any value from Map size. --MentalMouse42 (talk) 11:04, 25 August 2019 (UTC)
