There is no such option. You have to <a href="https://www.tenforums.com/tutorials/5990-change-dpi-scaling-level-displays-windows-10-a.html" rel="noreferrer">modify the DPI scaling of windows</a>, which will make all "legacy" shell applications appear larger to compensate for the high DPI of the device.

If you don't want to modify the settings, you might want to try running creator with an <code>QT_SCALE_FACTOR=2</code> env var or so.

Create a <code>startScaled.cmd</code> in creator's exe directory with the content:

<pre><code>@echo off 
set QT_SCALE_FACTOR=2
qtcreator.exe
</code></pre>

And use this to start creator up-scaled.

blocks|key|653743|text|对于我来说，在linux上，更改桌面DPI缩放对QT侧边栏字体尤其没有帮助，尽管大多数其他东西都可以进行缩放。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|653744|然而，比例因子变量法确实有效。下面是我使用的脚本，只需修改已安装的菜单快捷方式，以便QtCreator运行它，而不是直接运行qt创建者可执行文件：|653745|+++#!/bin/bash

+++export+QT_SCALE_FACTOR=1.5

On linux mint for me, changing the desktop DPI scaling doesn't help with QT sidebar font in particular although most other things do scale. 

The scale factor variable method does work though. Here's the script I used and just modify the installed menu shortcut for QtCreator to run it instead of directly running the qtcreator executable: 

<pre><code> #!/bin/bash
 #my_qtcreator.sh
 export QT_SCALE_FACTOR=1.5
 /opt/Qt/qtcreator-4.2.2/bin/qtcreator
</code></pre>

I had the same problem running on Linux Fedora 27/Gnome/Wayland on a 4K monitor (3840 x 2160). A microscope was nearly necessary to read most of Qt Creator's window panes.

This fixed it for me:

Create <code>qtcreator</code> in an executable file in my path with this content:

<pre><code>QT_AUTO_SCREEN_SCALE_FACTOR=1 ~/Qt/Tools/QtCreator/bin/qtcreator $1 $2 $3 $4 $5 $6 $7 &amp;
</code></pre>

An alias would do just as well. It is not necessary to export any environment variables. This uses the shell syntax which sets an environment variable only for the process to be created. I have Qt installed in my directory instead of system-wide.

I got the environment variable from @joelostblom's comment on the answer <a href="https://stackoverflow.com/a/46959458/198536">here, above/below</a> pointing to <a href="https://doc.qt.io/qt-5/highdpi.html#high-dpi-support-in-qt" rel="nofollow noreferrer">this Qt reference</a>.

With Gnome already set to scale by 200%, a try of <code>QT_SCALE_FACTOR=2</code> resulted in ridiculously large text. But using QT_AUTO_SCREEN_SCALE_FACTOR and scaling by one was enough of a nudge for it to react properly to Gnome's settings.

I had the same nasty problem in Ubuntu , the solution is easy.
<ol>
<li>In the top left menu , choose <code>Tools &gt; Options &gt; Environment</code>
</li>
<li>Mark the checkbox that says &quot;Enable high DPL scaling&quot;
</li>
<li>Restart and it should work
</li>
</ol>

I use QT Creator on surface pro4 and the font of menu is too small:
<a href="https://i.stack.imgur.com/GgU5o.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/GgU5o.jpg" alt="enter image description here"></a>

what should i do to change the font size?
