45+ Sims 4 Trait Mods
Looking to add a little more personality to your game?
These Sims 4 trait mods will spice up your gameplay and let you build Sims that are way more dynamic, dramatic, and maybe even a little unhinged (in the best way)
Most of the mods on this list add fresh new traits right into CAS, so you can craft your perfect chaos gremlin from the start. But a few go even further—letting you assign extra traits and tweak things mid-game for maximum storytelling power.
If you’re ready to stop settling for vanilla and start serving flavor, these are the Sims 4 trait mods you need.
Best Sims 4 Trait Mods

1. Editor’s Pick: 100 Base Game Traits Pack by Vicky Sims
Normally I’m all about mixing and matching smaller trait packs—but if you’re new to the world of custom traits or just want a mega dose of personality, this one’s a no-brainer.
This pack adds 100 (!) new traits that range from light-hearted quirks to deep-seated neuroses. Some of them you might recognize from older Sims games (hello, nostalgia), while others are fresh takes that help shape more nuanced Sims.
The traits are thoughtfully grouped into five juicy categories:
- 🧠 Emotions & stimulation – How they feel things
- 💬 Social identity – Extroverts, image-obsessed divas, lone wolves, etc.
- 💘 Romantic tendencies – Flirty? Awkward? Emotionally distant? Yup.
- ✨ Appearance-based vibes – Think: beauty, grooming, or dramatic flair
- 🎨 Innate talents and flaws – Gifted artists, unlucky klutzes, the whole spectrum
I love how much variety this pack brings—it’s the perfect starting point if you’re ready to stop playing cookie-cutter Sims and start building some true weirdos. Pair this pack with a custom loading screen and CAS background for the ultimate personalized game.
Lifestyle Traits

2. Shy Trait by MarlynSims
This trait does exactly what it says on the tin—Sims with the Shy trait are a little more reserved and take longer to warm up to others.
Charisma comes slower, and building relationships with other Sims takes more effort. But hey, silver lining? They absolutely thrive with animals.
Perfect for storytelling introverts, awkward loners, or just giving your Sim a more relatable social edge.

3. Glamorous Trait by KiaraSims4Mods
Sims with the Glamorous trait are here for the spotlight.
They climb the social ladder faster, gain fame like it’s their birthright, and ooze charm wherever they go. You’ll need both Get Famous and Vintage Glamour for this one, but if you love playing with high society drama? It’s so worth it.
- ✨ Learn Charisma 1.5x faster
- ✨ Gain Fame 1.5x faster
- ✨ Get mood boosts from parties, butlers, spending money, and bragging about their luxe lifestyle
These Sims don’t just sparkle—they blind. Ideal for your next celebrity rags-to-riches story or over-the-top socialite saga.

4. MBTI Personalities by Zero’s Sims 4 Mods
This mod brings the iconic 16 MBTI personality types to The Sims 4, giving your Sims an extra dose of realism (and a touch of overthinking).
It doesn’t overhaul gameplay in a huge way, but it does sit cleverly in the background—subtly influencing your Sims’ behavior and adding a new layer to their existing traits.
🧪 There’s even an MBTI typing skill and two in-game personality tests to help your Sims discover their type.
🔄 Each test pulls from your Sim’s traits, so results can vary—and yes, you can retake them as many times as you want (perfect for indecisive Sims or chaotic storytellers).
This one’s great for storytellers who want deeper, more nuanced characters—or players who just want to know if their Sim is an INFJ or a total ESTP.

5. Book Smart and Street Smart Traits by Jane Simsten
These two traits are perfect for adding flavor to your Sims’ learning style.
- ✔️ Book Smart Sims level up faster when they’re reading, studying, or generally being adorable little nerds.
- ✔️ Street Smart Sims thrive in hands-on situations—think charisma, fitness, mischief, and other action-based skills.
It’s a great way to personalize your Sim’s growth path and make their skill-building journey feel more authentic. Plus, it’s ideal for rags-to-riches, university gameplay, or just playing favorites with how your Sims learn.

6. Grandparent Trait by KiaraSims4Mods
This trait is made for your family-focused elders who love helping out with the next generation. Sims with the Grandparent trait:
- Learn the Parenting skill faster

7. Zodiac Trait Pack by SkillfulSimmer340
This trait pack brings all 12 Zodiac signs into The Sims 4—each with its own unique personality boosts and quirks that affect gameplay in subtle (and sometimes hilarious) ways.
Here’s a peek at what some signs can do:
- ♓ Pisces: Logic and creativity skills come naturally
- ♍ Virgo: Comedy and work performance get a nice little boost
- ♌ Leo: Probably throws drama and glitter in equal measure (okay, not canon—but they should)
It’s a simple way to add major personality with just one trait. Bonus points if you combine it with Zodiac-themed makeup or CAS storytelling—because you know a Scorpio Sim is going to need a signature look.

8. Faithfulness Mod + Traits V6 by Vicky Sims (chingyu1023)
This mod gives you total control over romance autonomy in The Sims 4, so your Sims aren’t just randomly making out with the mail carrier unless you say so.
You get nine custom Faithfulness traits (available both in CAS and as Reward traits), and they actually mean something—because Sims will behave differently in romantic situations depending on what they’ve got going on.
Here’s the juicy part:
✔️ You can install just the traits, just the mod, or both.
✔️ Sims will now follow romance rules based on their faithfulness levels.
✔️ You can ask a Sim to be faithful (finally!), or put the brakes on infidelity altogether.
✔️ Fully integrates with Vicky’s other mods, like the 100 Base Game Traits Pack.
🚫 Heads up: This mod does not play nicely with Better Romance—they both mess with the same core files and will throw hands if used together.
If you’re tired of watching your married Sims flirt with every townie at karaoke night, this mod brings order to the romantic chaos—or lets you lean into it with full control.

Health-Related Traits

37. Deaf Trait by DaleRune
This mod introduces a Deaf trait that covers both deafness and being hard of hearing (HoH), and it’s been thoughtfully designed with gameplay and realism in mind.

What it does affect is skill growth:
🎵 Skills like musical instruments, DJ Mixing, Singing, Media Production, and even Child Social and Entertainer career performance gain experience at half the normal speed—unless your Sim is using hearing aids or cochlear implants, which bump the multiplier up to 0.8.
This is a respectful, nuanced mod that adds valuable representation and depth without being heavy-handed.
