The Sims 4: A Complete Guide To Traits

Though there are plenty of layers to the gameplay in The Sims 4, the traits you assign to your Sim when you first create them are strong enough to influence everything they do. Adult Sims have three traits each, and with a sprawling spread to choose from, every Sim experiences life differently.

Whether it’s the innate traits you give your Sim on creation, reward traits from completing aspiration or working hard in careers, or childhood traits that stick with smaller Sims for life, traits can shape your entire experience. Here’s a detailed look at every trait in The Sims 4.

Updated on August 15, 2024: Now that a few packs have come out since we first published our Sims 4 traits guide, we're back to add all the extra traits we've gotten in-game since to help you make your Sims as individualistic as they can be! We also put our tables into expandable windows to save your from having to scroll forever to find the Sims 4 trait you're looking for.

What Are Traits?

Traits Overview

In The Sims 4, emotions are more varied than ever before, with Moodlets introduced in this series entry. And while normal gameplay can impact moodlets, your Sims are more prone to certain emotions depending on their traits. Though townie Sims appear with their traits already set, you can choose up to three traits for Sims you make yourself in Create-a-Sim. Any Sims you download from the gallery will also have a set of traits.

Adult Sims have three trait slots by default, but they may earn additional traits based on life experiences, completed aspirations, and more. More on that below!

Overall, traits in The Sims 4 combine to form your Sim's unique personality. For example, Sims with perfectionistic traits will behave much differently than sloppy Sims, while hardworking Sims are more driven in their goals than lazy ones. Because of this, you're truly able to make hundreds of combinations from the list of all traits in The Sims 4.

The list of available traits in The Sims 4 grows as you get new expansion packs. These often have additional traits to give your Sims, heavily influenced by the content of the pack. For example, you'll find plenty of equestrian-themed traits in the Horse Ranch pack, while Get Together offers more interpersonally social traits for your Sim.

Some packs drastically change how heavily traits in The Sims 4 weigh into things, such as the Lovestruck pack introducing the Turn-Ons and Turn-Offs system that makes certain traits more or less attractive to Sims with a given preference. More on that system here, as it's currently exclusive to Lovestruck.

Unless you use the Retraiting Potion (or a couple of cheats), you cannot change your Sims' three base traits on the UI or via the "Modify Sim in CAS" option. You can, however, work toward swapping them through behavioral changes. For example, if a Mean Sim continues to do nice things, you may have a chance to swap the Mean trait for the Good one.

Traits Come In Four Categories

Since players may struggle to keep traits in line without them, traits fall into one of four categories when you're assigning them in Create-a-Sim. These categories are:

• Emotional Traits, which deal with your Sim, their feelings, and how likely they are to feel different things.
• Hobby Traits that can help your Sims advance in their goals and hobbies more quickly.
• Lifestyle Traits, which inform how your Sim approaches the world around them.
• Social Traits that flesh out your Sims' interactions with other Sims and animals.

By choosing traits from across several categories, you may help make your Sim feel more varied. Additionally, if you're not sure what you'd like your Sim to be like, you can always use the randomize option to select three traits at random.

What Are Reward Traits?

There are also traits available in The Sims 4 that are inherited traits as your Sim moves through their life. Whether this is from completing one of their aspirations entirely, reaching the top of their chosen career path, developing relationships with other Sims around their world, or more, there are plenty of ways to add extra traits in The Sims 4.

Though these traits are not available to select in Create-a-Sim, Sims can still earn these traits as a result of your gameplay decisions and happenings. They're typically longer-term goals during regular gameplay unless you're using a few cheats - we won't tell you what to do, just how to do it.

All Basic Sim Traits

In the tables below, we've elaborated on each of the traits you can assign to fully-grown Sims of any species. These are the traits available in CAS that can be chosen for Sims you're creating, or given to Sims as they age up, which cannot be changed.

These appear in the order they appear on the trait selection page, and we've noted which traits are exclusive to expansion packs, too.
