Paint Tool SAI is a popular program for digital art and illustrations. One of its key features is pen pressure sensitivity, which allows artists to vary the width of their pen strokes by adjusting the pressure they apply to the tablet. However, some users have reported issues with pen pressure not working in SAI. This can be due to various factors, such as driver issues, incorrect settings, or compatibility problems with certain tablet models. To adjust pen pressure in Paint Tool SAI, users may need to update or reinstall their tablet drivers, modify brush settings, or change tablet API configurations. Troubleshooting steps may vary depending on the specific tablet model and driver software being used.

What You'll Learn
Ensure Min Size is under 100%
To adjust pen pressure in Paint Tool SAI, it is important to ensure that the "Min Size" in your brush settings is set to a number under 100%. This setting plays a crucial role in determining the range of pen pressure available to you. By lowering the "Min Size", you increase the maximum pen pressure that can be detected by the software, providing a wider range of pressure sensitivity.
To locate the "Min Size" setting, open the brush settings in Paint Tool SAI. Within these settings, you will find the "Min Size" option, which you should adjust to a value below 100%. This adjustment will give you greater control over the pressure applied to the digital brush, allowing for more nuanced and expressive strokes in your digital artwork.
It is worth noting that while a lower "Min Size" increases the maximum detectable pressure, it does not restrict the lighter pressures. Even with the "Min Size" set to a lower value, you can still create delicate and subtle strokes by applying less pressure on the pen. This flexibility in pressure sensitivity is what allows digital artists to create a diverse range of stroke widths and achieve intricate details in their artwork.
The "Min Size" setting is a powerful tool that can enhance your creative capabilities in Paint Tool SAI. By ensuring that it is set below 100%, you unlock the full potential of pressure sensitivity, enabling you to vary the width and intensity of your brush strokes with precision. This adjustment is a key step in customizing your digital art tools to match your artistic vision and desired style.
Remember, the specific steps to access and adjust the "Min Size" setting may vary slightly depending on your version of Paint Tool SAI and your digital art setup. However, the fundamental principle remains the same: keeping the "Min Size" below 100% ensures that you can take full advantage of the pressure sensitivity features offered by your digital art software and hardware.

Set Click detection pressure to 0
To adjust pen pressure in Paint Tool SAI, you must first access the brush settings. Here, ensure that the "Min Size" is set to a number under 100%. A lower "Min Size" allows for a higher range of pen pressure.
Next, on SAI's toolbar, click "Others," then "Options." This will open the "Digitizer Support" tab, where you can adjust the "Click detection pressure." Setting this value to ""0" will give you absolute pen pressure.
It's important to note that some artists prefer to adjust the "Min Size" setting to suit their preferences. If you're experiencing issues with pen pressure, it's recommended to set the "Click Detection Pressure" to "0." If it's already set to "0," try setting it to "100," click "OK," and then set it back to "0" again.
Additionally, you can download a driver called "N-trigger" to enhance pen pressure sensitivity in Paint Tool SAI. After installing the driver, you can access the ""Digitizer Support" tab in the Options menu and adjust the "Click detection pressure" as needed.

Change the Tablet API from WinTab API to Windows API
To adjust pen pressure in Paint Tool SAI, you must have a pen tablet; the brand does not matter, but Wacom is the most popular. You should ensure that you have installed/updated your driver.
If you are still facing issues with pen pressure sensitivity, the following steps may help:
- Uninstall your current Wacom driver and reboot your computer.
- Make sure SAI and other drawing programs are closed.
- Open Program Files and delete all folders that say "Wacom" or "Tablet" (unless you have a tablet computer).
- Reinstall your Wacom driver and reboot your computer.

If the issue persists, you may need to adjust your brush settings in SAI. Ensure that the Min Size is set to a number under 100%. A lower "Min Size" allows for a higher range of pen pressure.
To change the Tablet API from WinTab API to Windows API, you can use the WintabEmulator, which is a "quick hack" that uses the Windows 8 Pointer API to simulate a tablet accessible via the Wintab API. This was specifically created to allow Paint Tool SAI to access pen pressure information on a Microsoft Surface Pro tablet.
- (Optional) Build the program in Visual Studio 2012.
- Rename WintabEmulator.dll to wintab32.dll.
- Copy wintab32.dll to the same directory as the program executable.
- (Optional) Copy wintab.ini to the same directory as the program executable.
- (Optional) Edit wintab.ini.
Please note that when emulation is enabled, normal tablets cannot be accessed via the system Wintab driver.
