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 Some of these will almost definitely change over time, so if you spot something incorrect/outdated, please take a moment to update it.

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.".
• 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

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).
  • While an improvement over the previous limit of 50 m, Torley thinks this limit is ridiculous because Second Life is 3D. 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.

Chat (text)

• Whisper distance (done via scripting objects) - 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.

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. ;)

Land

• Max. parcel size - 65,536 m2
  • Covering a whole region, or square on the World Map.
• Min. parcel size - 16 m2
• 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 an Openspace region)
• 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.
  • 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

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)
  • About Land > Options tab - ~3:2 (178x117 pixels)
  • Group Information > General tab's "Group Insignia" - 1:1 (126x126 pixels)
• Maximum texture size - 1024x1024 pixels
  • We strongly recommend you use as small textures as possible because larger ones consume more memory and take substantially longer to load.
