If you’ve used WizTree to check your disk space, you know it works quickly and well. But let’s be honest—the default font size in the interface can be hard to read, especially if you need larger text. If you’ve been wondering, “How can I change the font size in WizTree?” don’t worry. I’ve got some easy solutions for you. Let’s go over a few ways to make WizTree easier to read.
Does WizTree Have an Option to Change the Font Size?
You might ask, “Can’t I just change the font size in WizTree’s settings?” Unfortunately, no—at least, not in 2025. WizTree is great for disk analysis, but it doesn’t let you change the font size. When I first opened WizTree, I was surprised to find there wasn’t a font size setting. I thought this would be helpful, especially for people who need larger text.
I checked the official documents and FAQ, and it looks like the developers focus more on performance than on changing the UI. Many users, including some on forums from 2022, have asked for this feature. But for now, it’s not available. Don’t worry, though! There are still ways to make the font bigger with some easy tricks. Let’s take a look at them.
Simple Ways to Change Font Size
While WizTree doesn’t let you change the font size in the app, here are a few easy tricks you can try to make the text easier to read. These methods won’t be perfect, but they’ll help you adjust the font.
Windows 10/11 Display Scaling (Best Option)
One of the easiest ways to change the font size in WizTree is by using Windows’ display scaling feature. If you’re on Windows 10 or 11, right-click on your desktop, go to Display Settings, and find “Scale and Layout.” From there, you can increase the scaling to 125% or 150%. This will make the text bigger in all your apps, including WizTree.
This works well, but there’s a downside: it affects all your apps, and it can make text blurry in some programs, especially on lower-resolution screens. But overall, it’s an easy way to get larger text without much effort.
Application-Specific High DPI Scaling
If you’re using Windows 11, here’s another helpful trick: application-specific high DPI scaling. To do this:
- Right-click the WizTree64.exe file (the one you use to open the app).
- Click Properties and go to the Compatibility tab.
- Click “Change high DPI settings.”
- Check the box for “Override high DPI scaling behavior” and select “System (Enhanced).”
This trick sharpens the text and makes it easier to read when scaling up. I’ve used it myself, and it really makes a difference if the text is blurry after changing the display settings.
Windows Accessibility Features
For a quick fix, Windows has some helpful tools. The Magnifier Tool (Win + Plus) lets you zoom in on any part of your screen. It’s perfect if you need to see something clearly without making permanent changes.
Also, if you’re using Windows 11, you can increase the global text size. Go to Settings > Accessibility > Text Size. This will make text bigger across your system, including in WizTree. It may not be as precise as adjusting the font size in the app, but it’s a good solution if you need a fast fix.
Registry Tweaks (Advanced Users)
This method is for more tech-savvy users. I looked into registry tweaks for changing WizTree’s font size, but didn’t find any specific settings for it. However, advanced users might try editing the registry to force a font change. Be careful—editing the registry can be risky. Always back it up before making any changes.
Third-Party Tools (Use Carefully)
If the built-in methods don’t work, third-party tools can help adjust WizTree’s font size. But use them with caution, as they can cause problems.
- Winaero Tweaker lets you change the font size for all apps. But it affects every app on your system, not just WizTree. I’ve used it before, but it can mess with some app layouts. So, be careful.
- NoVirusThanks DPI Scaling Fixer forces DPI scaling on specific apps. It could help adjust WizTree’s font size without affecting everything on your system. However, it can cause issues with other apps, so use it carefully.
Alternative Launchers
If you don’t want to tweak many settings, Microsoft PowerToys can help. The “Always on Top” feature lets you zoom in on WizTree in a window, making it easier to read. While it won’t change the font size, it’s a quick and easy fix. It’s like zooming in on the app, which can be useful without making permanent changes.
Alternatives to WizTree with Customizable UI
Sometimes, even after trying all these tricks, you might want an app that gives you more control over the font size and layout. If WizTree still isn’t working for you, here are some great alternatives.
TreeSize Free/Pro
TreeSize is a disk space analyzer that lets you adjust the column widths and view types. This extra flexibility makes it easier to read and organize the data. I’ve used TreeSize for a while and love how it lets you change the layout to fit your needs.
WinDirStat
WinDirStat is an open-source tool that’s easy to use. It lets you zoom in with Ctrl + Mouse Wheel, making the text and interface bigger without changing any settings. I’ve used it myself, and it’s very user-friendly. It’s a great option for anyone who wants a simple solution.
SpaceSniffer
SpaceSniffer is different from the others. It doesn’t adjust text size but lets you change block sizes and colors in its graphical interface. It’s a fun, visual way to see your disk usage. If you like colorful and interactive layouts, SpaceSniffer is worth trying.
Conclusion
While WizTree doesn’t have an option to change the font size directly, there are still plenty of ways to make it easier to read. The easiest method is to adjust the Windows display scaling, which will change the text size in all your apps. If you want more control, try alternatives like TreeSize or WinDirStat, which give you more customization.
If none of these solutions work for you, consider reaching out to WizTree’s developers to ask for font size options. In the meantime, these tips should make your experience a lot more comfortable.
