An object limiter is a software restriction on the number of objects that can be placed on a lot. Object limiters exist to prevent game crashes due to excessive memory usage and to ensure the game performs reasonably well on console hardware. Since console producers traditionally also had mandatory tests to ensure the game didn't crash during long intensive play sessions, this gave further reason to prevent hardware overstress.

A limiter is present in all console versions of The Sims prior to The Sims 4, as well as The Sims Social. Console games are usually limited to about 100-150 objects. In The Sims Social, players can place up to 800 objects.

The object limiter will warn the player if they are nearing the limit.^{[TU:SITC][TS2C][TS3C]} In The Urbz: Sims in the City, this is done by means of modal alerts. In most games, a meter appears which visually represents the object limit, which fills as more objects are added. This meter is represented with an icon of a house on fire in most games starting with The Sims 2 for consoles.

The specific name of the object limiter varies by game.

• Feng Shui in The Sims, The Sims Bustin' Out, and The Sims 2 (PSP).
• Fire Code in The Urbz: Sims in the City, The Sims 2 and The Sims 2: Pets.
• Fire Meter in The Sims 3 and The Sims 3: Pets.

Usually the games will refuse to place an object if it would go over the limit. In The Sims 2: Castaway, the game will instead compensate for going over the limit by setting one of the items in the house on fire.

Technical details

Object limiters are not present in Windows/macOS/Linux games (excluding the web-based The Sims Social) as consoles tend to have less memory and fewer resources compared to PCs.

For example, the PlayStation 3 and Xbox 360 consoles both have 512MB of RAM (with the PS3 having its RAM split 256MB for graphics and 256MB for general usage).^[1][2] The Sims 3 on PC/Mac requires 1~2GB^[3] of RAM. Because of this, The Sims 3 for console has the object limiter, whereas the PC version does not.

The Sims 2 on home consoles had similar constraints, and The Sims on home consoles had to render in full 3D while the original PC game was almost entirely in isometric 3D (and rendered only a few things in proper 3D), thus increasing RAM requirements compared to the PC game.

If a console game is played using an emulator, there will still be an object limit regardless of the host system, as the data and programming of the base game is not changed by emulation.

The Sims 3 (Windows/macOS)

The Sims 3 has no hard limit on objects or on the amount of walls (Neither on lengths or on individual walls that don't touch each other), though the loading times to enter or leave Buy/Build Mode begins to get much longer past the "1,000 individual walls" point, with leaving from Buy/Build Mode to Edit Town reaching almost 2 minutes around the 2,500-walls mark. Lag in placing new walls also becomes present around the 800 mark, and wall shadow generations begin to struggle around 2,100.

The Sims 4

The consoles that The Sims 4 are available for (PlayStation 4, PlayStation 5, Xbox One, Xbox Series X/S) have a similar amount of RAM as what the system requirements of the PC version list, and this may be the reason why there is no object limiter in the console version of the game.

Mandated software stability tests by console producers had also become less strict in the time since the then-previous home console game (The Sims 3: Pets (console)),^[4] so the potential factor of being denied release if the game crashed often was no longer omnipresent.
