Create-A-Sim (CAS) remains the heart of The Sims 4 experience, especially as the game's library of clothing, hair, and accessories has expanded exponentially by 2026. However, the default user interface, which provides only two columns for browsing items, has become a significant bottleneck for productivity and creativity. For players with dozens of expansion packs and thousands of pieces of custom content (CC), scrolling through an endless vertical list is inefficient. The solution that has defined the community's approach to this problem is the More Columns in CAS mod.

This modification redesigns the catalog panel, allowing for a much denser display of items. By increasing the column count, players can see more of their collection at a single glance, drastically reducing the time spent scrolling and making it easier to coordinate outfits. Understanding how to implement this mod correctly is essential for maintaining a stable game while optimizing the UI for your specific hardware.

The Evolution of CAS Navigation

When The Sims 4 was first released, a two-column layout was sufficient for the base game's limited wardrobe. Fast forward through years of releases, including major expansions like Businesses & Hobbies, and the sheer volume of assets is staggering. A standard search for a specific pair of boots or a particular hairstyle can now involve scrolling past hundreds of thumbnails.

The More Columns mod, originally developed by the creator Weerbesu, has been the primary tool for solving this. It doesn't just add columns; it recalibrates the entire layout of the CAS screen. The randomization buttons, filter bars, and swatch panels are all shifted and resized to accommodate the wider catalog. This ensures that the interface remains functional and aesthetically pleasing, rather than just cluttered.

Choosing the Right Number of Columns

The mod is typically offered in four distinct versions: 3 columns, 4 columns, 5 columns, and 6 columns. Choosing the correct one is not just a matter of preference; it is a technical decision based on your monitor's resolution and the game's UI scaling settings.

3 Columns: The Balanced Entry

This version is ideal for players using standard laptop screens or older monitors. It provides a 50% increase in visibility over the vanilla game without feeling overly cramped. It is the safest choice for those who want a slight boost in efficiency while keeping the thumbnails large enough to see fine details clearly.

4 Columns: The Modern Standard

For most players on 1080p (Full HD) monitors, the 4-column version is the "sweet spot." It balances item density with readability. It effectively doubles the amount of content visible compared to the original game. Most content creators and regular players find this to be the most comfortable setting for daily gameplay.

5 Columns: The Power User Choice

If you are running the game on a 1440p (QHD) display or have adjusted your UI scale to be smaller, the 5-column version offers professional-grade efficiency. It is particularly useful for players who manage massive CC folders (over 10GB) and need to see large sections of their inventory at once.

6 Columns: Maximum Density

Reserved for 4K monitor users or those who prefer a very small UI, the 6-column version transforms CAS into a high-density grid. While it offers the highest speed for finding items, it requires significant screen real estate. On lower resolutions, this version will likely cause the UI to overlap with the Sim model or go off the edge of the screen.

Technical Requirements and Screen Resolution

One of the most common mistakes players make is installing a version of the mod that their monitor cannot support. If the columns exceed the horizontal space available, the interface will break. Below are the recommended minimum resolutions for each version:

  • 3 Columns: Minimum resolution of 1280x720. Recommended for 1366x768.
  • 4 Columns: Minimum resolution of 1600x900. Highly recommended for 1920x1080.
  • 5 Columns: Minimum resolution of 1920x1080 (may require UI scaling adjustments). Recommended for 2560x1440.
  • 6 Columns: Minimum resolution of 2560x1440. Recommended for 3840x2160 (4K).

If you have a 1080p monitor but really want 5 columns, you can achieve this by going into the game's Graphics options and reducing the "UI Scale" slider. By making the overall interface smaller, you create more physical room for the additional columns to fit without overlapping the Sim.

Proper Installation Procedure

Installing the More Columns mod is straightforward, but it requires precision. Because this is a UI mod, it is more sensitive than a simple piece of custom furniture or clothing.

  1. Preparation: Before adding the mod, ensure your game is fully updated to the latest version. UI mods are almost always broken by major game patches, and using an outdated version of this mod can lead to a completely unusable CAS screen.
  2. Download Selection: You must choose only ONE .package file. For example, if you want 4 columns, download More_CAS_Columns_(4_Columns).package. Do not put all four versions into your folder, as they will conflict, resulting in the game defaulting back to two columns or crashing.
  3. File Placement: Navigate to your Sims 4 Mods folder. This is typically located at Documents > Electronic Arts > The Sims 4 > Mods.
  4. Organization: It is highly recommended to place this mod in a subfolder named "UI Mods" or "CAS Columns" to make it easier to find during game updates. However, remember that mods should not be buried more than one subfolder deep.
  5. Game Settings: Launch The Sims 4. Go to Game Options > Other. You must have "Enable Custom Content and Mods" and "Script Mods Allowed" checked. Even though this is primarily a .package mod, some UI modifications rely on script permissions to function correctly.
  6. Restart: Apply changes and restart the game to initialize the new layout.

Managing the Update Cycle

As of 2026, The Sims 4 continues to receive regular updates. For UI mod users, patch day requires caution. Whenever Electronic Arts releases a new expansion pack or a significant bug-fix patch, the internal code for the CAS screen often changes.

When a patch is released, the More Columns mod is frequently "broken." Symptoms of a broken UI mod include:

  • Missing icons for categories (hair, tops, bottoms).
  • White squares or "llama" icons appearing in place of UI elements.
  • The "Save" or "Checkmark" buttons becoming unclickable or disappearing.
  • The game hanging on the loading screen when entering CAS.

If you experience these issues after an update, the first step is to remove the More Columns mod from your folder and check if the game works normally. You will then need to visit the creator's official community pages (such as Weerbesu's Patreon) to download the updated version compatible with the new patch. Never attempt to use a version of the mod that was released before a major game update.

Enhancing Workflow with Complementary Mods

While more columns solve the visibility issue, other modifications can further enhance the CAS experience when used alongside this mod.

UI Cheats Extension

Many players combine More Columns with the UI Cheats Extension. This allows for right-clicking on specific UI elements to bypass certain limitations, such as instantly promoting a Sim or changing the time of day while in CAS. These mods are designed to be compatible, provided both are kept updated.

Stand Still in CAS

By default, Sims move their heads, laugh, and play animations while you are trying to edit them. This can be frustrating when you are trying to see how a specific column of hairstyles looks. A "Stand Still" mod keeps the Sim in a neutral pose, which, when combined with the 4 or 5-column view, allows for a much more surgical and precise editing process.

CAS Overhaul Lighting

The default CAS lighting can sometimes be harsh or unrealistic. Installing a lighting overhaul mod alongside the columns mod ensures that as you browse your expanded catalog, you are seeing the colors and textures of the clothing exactly as they will appear in the lived-in world of the game.

Troubleshooting Common Issues

Even with a perfect installation, you may encounter visual glitches. Here is how to resolve the most frequent problems reported by the community.

The "White Button" Glitch

If all the buttons in your CAS look like white blocks, it almost always means the mod is outdated. This happens because the game's internal image atlas has changed, and the mod is looking for icons that no longer exist at those coordinates. Delete the old file and wait for the creator to release a version compatible with the latest game patch.

Overlapping UI Elements

If the item catalog is covering your Sim, you have selected a column count too high for your resolution. For example, trying to run 5 columns on a 1366x768 laptop screen will result in the catalog extending into the center of the screen. Switch to the 3-column version or decrease your UI Scale in the game settings.

Columns Not Appearing

If the game loads but you still only see two columns, check if you have another UI mod that might be conflicting. Mods that change the background of CAS or add custom poses sometimes include their own UI files. Ensure that the More Columns mod is the only file in your folder that specifically targets the CAS.package resources.

Create-A-Pet Issues

The Create-A-Pet interface is technically different from the standard human CAS. If you have the Cats & Dogs expansion, you might notice that the columns look slightly different or more crowded when editing animals. The mod is designed to handle this, but it requires even more horizontal space for pets. If you spend a lot of time editing occults or pets, the 4-column version is generally the most stable across all species.

Impact on Game Performance

A common concern is whether adding more columns will slow down the game. Technically, the More Columns mod is very lightweight. It is a set of XML and CSS-like instructions that tell the game where to draw the boxes on the screen. It does not increase the memory usage of the game in a significant way.

However, there is a secondary effect: because you can see more items at once, the game has to load more thumbnails simultaneously. If you have a very slow hard drive or an older CPU, you might notice a slight stutter when you first click on a category (like "Short Hair"). This isn't the mod's fault, but rather the game engine trying to render 40 thumbnails at once instead of 20. For most modern systems, this impact is negligible.

Conclusion: A Necessary Upgrade for 2026

As we look at the state of The Sims 4 in 2026, the sheer volume of content makes the More Columns mod less of a luxury and more of a necessity for dedicated players. It respects the player's time by streamlining the creative process. Whether you are a casual player looking to organize your expansion pack items or a hardcore CC collector with a massive digital wardrobe, choosing the right version of this mod and keeping it updated will transform your game experience.

By following the resolution guidelines and maintaining a clean Mods folder, you can ensure that your CAS remains a place of creativity rather than a source of frustration. The jump from two columns to four or five is one of the most immediate and satisfying upgrades you can make to your game's user interface.
