This page is an easy reference to common queries about Second Life limits. Some of these will almost definitely change over time, so if you spot something incorrect/outdated, please take a moment to update it. Also see the Knowledge Base counterpart of this article.

Building

  • Max. prim dimensions (non-megaprim) - 10x10x10 m
  • Min. prim dimensions - 0.01x0.01x0.01 m
  • Max. # of prims in a linkset - 255
  • Max. link distance - See Linkability Rules.
  • Max. # of prims in a physical object - 32
    • If you try to link more, it'll either say "Can't enable physics for objects with more than 32 primitives" or "Object has too many primitives -- its dynamics have been disabled.".
    • Note that this limit includes the driver and passengers of physics-enabled vehicles, e.g. if you are making a car to sit 4 people, 28 prims are available for the car itself.
  • Max. build height - 4,096 m (SL 1.20.x or later required)
    • This is 768 m for viewers prior to SL 1.20.x
  • Max. prim name length - 63 bytes UTF8 string
  • Max. prim description length - 127 bytes UTF8 string

Avatar

  • Max. # of attachment points - 30 for avatar, 8 for HUD.
    • They can be viewed in Edit menu > Detach Object.
  • Max. unassisted fly height - Stable hover almost 150 m above the ground (terrain mesh).
    • (You can easily acquire a flight attachment to fly up to seemingly infinite heights.)
  • Common shoe sizes - Most women's shoes are designed for a size 0 (zero) foot. Men's generally scale up to 14. You can check this by going to Edit menu > Appearance and clicking on the Shape > Legs tab.
  • Max. length of avatar name - 31 for first name, 31 for last name, 63 for total (including the space).

Chat (text)

  • Whisper distance - 10 m
  • Chat distance - 20 m
  • Shout distance - 100 m
    • Rule of thumb: when you're at default zoom (View menu > Reset View), if you can see another other person's nametag, they can see your chat. If they're far enough away that you don't see a nametag, they won't "hear" you unless you shout.
  • Max. length of a chat message - 1023 bytes/single-byte characters
    • The same holds true for an IM<->email replies.
  • Capped - Maximum number of offline messages (involving IMs, inventory offers and group notices) received before messages get capped is 25.

Profile

  • 2nd Life tab's About field - 500 characters
  • Picks tab - 10 picks with 1023 characters each
  • 1st Life tab's Info field - 250 characters
  • My Notes - 1022 characters

Groups

  • Max. # of groups you can belong to - 25
    • Roles within groups are sort of like sub-groups. In many cases, you can use them instead of creating new groups.
  • Min. # of members in a group - 2
    • A group with only 1 person for 48 hours will be disbanded (cancelled).
  • Max. # of roles allowed in a group - 10 (including "Owners" and "Everyone", which can't be deleted)

Inventory

  • Max. # of inventory items that can be sent in a folder - 42
    • Folders count as items too. This has more to do with packet size limits than cheeky Douglas Adams references. ;)
  • Max. notecard size - 65,536 bytes

Land

  • Max. parcel size - 65,536 m2
    • Covering a whole region, or square on the World Map.
  • Min. parcel size - 16 m2
  • Max. parcel name length - 63 characters
  • Region name length - min. 3 characters max. 25 characters (including spaces)[KB]
  • Max. "NO ENTRY" ban line height - 768 m above the terrain mesh.
    • This is if you're explicitly banned from a parcel. If the parcel is simply not public access or restricted to certain Residents/a group, then the access lines go up to 50 m above the terrain mesh.
  • Max. prims in a region - 15,000 (3,750 prims for a Homestead, 750 prims for an Openspace|Openspace region)
  • Max. Autoreturn value - besides "0" (which means: never), 999,999 minutes is the biggest autoreturn value.
  • Terraforming limits - Almost all mainland can be raised/lowered by +/-4 m. Estate (private island) terraformability is settable to a max of +/-100 m by the estate owner or managers. Bay City regions cannot be terraformed, and there may be others.--Shadoe Landman 13:07, 6 July 2008 (PDT)
    • A few, very old regions like Da Boom have a terraform range of +/-40 m.
  • Max. water height - 100 m
    • Region water height is usually 20 m, and adjacent regions should have the same water height, or else they'll look discontinuous.
  • Misc. estate limits - You can have a max. of 10 estate managers, 500 allowed Residents, 63 allowed groups, and 500 banned Residents.
    • See World menu > Region/Estate > Estate tab.
  • Mainland max. # of agents - 40 avatars/region
  • Island max. # of agents - 100 avatars/region (20 for a Homestead, 10 for an Openspace region)
  • Freeze Time - Land owners can freeze other Residents for up to 30 seconds.

Performance

  • Healthy Viewer FPS - Generally, FPS above 15 is good. The higher it gets, the smoother. You can check via Help menu > Lag Meter, or for more advanced usage, see View menu > Statistics Bar.
  • Avatar Rendering Cost scores - Learn all about it!

Scripting

For specific scripting limits, lookup calls in the LSL Portal.

Textures

  • Aspect ratios of profile, place, etc. pictures — all of these were measured at UI size = 1.000:
    • Search > All for "Classifieds", "People", and "Places" - 4:3 (256x192 pixels)
    • Search > Places and Classified tabs - ~7:5 (398x282 pixels)
    • Search > Land tab - ~7:5 (358x252 pixels)
    • Profile > 2nd Life tab - ~4:3 (178x133 pixels)
    • Profile > Picks tab - ~16:9 (288x162 pixels)
    • Profile > 1st Life tab - 1:1 (133x133 pixels)
    • Profile > Classifieds tab - ~3:2 (206x137 pixels)
    • Profile > Web tab - 1:1 (400x400 pixels) Note Scrollbars will eat 15 pixels
    • About Land > Options tab - ~3:2 (178x117 pixels)
    • Group Information > General tab's "Group Insignia" - 1:1 (126x126 pixels)
      • Some of these textures are shared (for example, Search > All place pages, Search > Places, and About Land > Options use the same image), so you should pick a well-balanced ratio and size.
  • Maximum texture size - 1024x1024 pixels
    • Some textures inworld have a resolution as high as 2048x2048; this is due to a previous limit that was higher.
    • We strongly recommend you use as small textures as possible because larger ones consume more memory and take substantially longer to load. See also Avatar Rendering Cost.

Misc

  • Billing and Trading Limits - Look at the linked page for LindeX currency exchange limits.
  • Contacts in Communication > Friends tab - A maximum of 20 simultaneous contacts can be selected to change permissions, remove, or invite for a conference chat.
