View source for Limits

This page is an easy reference to common queries about '''Second Life limits''' — just as the physical world has certain rules & restrictions, Second Life does too. Some of these will almost definitely change over time, so if you spot something incorrect/outdated, please take a moment to update it.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)

==Agent==
* '''Mainland region max # of agents''' - 40

== 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)''' - 5 m.
* '''Chat distance''' - 20 m.
* '''Shout distance''' - 100 m.
** Good 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 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

== 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 [https://support.secondlife.com/ics/support/default.asp?deptID=4417&task=knowledge&questionID=4235 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.

== 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''' - [http://blog.secondlife.com/2008/05/01/who-me-yes-you-couldnt-be-then-who-introducing-avatar-rendering-cost/ Learn all about it!]
