Fix a tiny interface on a 4K screen

The Sims 3 draws its interface at a fixed pixel size, so on a 4K monitor everything is tiny. Tiny UI Fix is not a normal package. It is a script that reads your game and your installed mods, then builds a tiny-ui-fix.package to match.

Download tiny-ui-fix-for-ts3.bat.zip from the Mod The Sims page (Windows). On a Mac, take tiny-ui-fix-for-ts3.command.zip.
Open the zip and double-click tiny-ui-fix-for-ts3.bat. On a Mac, right-click the .command file and choose Open. If PowerShell is missing, the script offers to download it.
A settings page opens in your browser. Set the UI scale (the page shows 1.5x and 2x examples at 4K), text scale and cursor scale, then generate the package.
Run the script again whenever you add or remove a core mod or another UI mod. It warns you when your mods have changed.

It needs nothing extra on Windows 10 or later, and macOS 10.13 or later on a Mac. To remove it, delete the TinyUIFix folder in your Mods folder or press Uninstall in the settings page. Known flaws listed by the author: some icons stretch, not every cursor scales, and a few checkbox captions stop responding to clicks.

If you only want larger text, Bigger Font Size is simpler: one .package, one size at a time. Its author warns that the work schedule and performance panels can look messy.

Installing a UI recolor

Cloud Blue UI, Gray UI and Golden UI are large .package files that override the game's interface images.

Pick one. The Golden UI page says to use one UI mod at a time, and Cloud Blue UI is listed as incompatible with other UIs, UI recolors and loading screen mods.
Put the file in Documents\Electronic Arts\The Sims 3\Mods\Packages.
If another mod that touches the interface overrides parts of it, give the recolor its own folder and priority. Gray UI and Golden UI both describe this: create Mods\uimod, move the file there, and add Priority 499 and PackedFile uimod/*.package to the end of Resource.cfg.
Clear the caches and start the game.

Cloud Blue UI also ships optional patch files that make it work with several other creators' UI mods, each with its own readme. Not all patches work together. Gray UI's page says NRaas mods work with it since its July 2016 update.

The Mods folder page explains Resource.cfg and priorities.

Interface options in engine patches

Sims3SettingsSetter by sims3fiend adds a borderless window mode and an adjustable UI font size. Its extra-resolution option for downsampling needs a separate UI scaling mod, which is where Tiny UI Fix comes in.
Smooth Patch by LazyDuchess made Create-a-Sim usable while clothes and patterns load. It has been unsupported since January 26, 2026, and its page points to S3SS. Tiny UI Fix lists one small glitch with it: clothing rows in Create-a-Sim may not snap back after scrolling.

Engine patches are .asi files for the game's Game\Bin folder, not the Mods folder. See graphics mods for the install steps.

FAQ

How do I make the Sims 3 UI bigger?

Use Tiny UI Fix by Just Harry. It builds a package that scales the interface by the multiplier you choose, such as 1.5x or 2x on a 4K screen.

Can I use two UI mods together?

Two full recolors cannot work together: they replace the same files. Tiny UI Fix is different. It is meant to be run again after you add or remove another UI mod, so it can sit on top of one recolor.

Do UI mods work with NRaas?

The NRaas panel mods are made to work together. Gray UI's page says NRaas mods work with it. Other recolors do not mention NRaas, so test on a spare save.
