How to change font size for JMeter?

Question

I am using JMeter with 2.13 version.
I want to increase font size for JMeter.

I have tried following question jmeter test plan navigation pane font size. However

Answer 1

Using Jmeter 3.2

Options > Zoom In

Zoomed some panes but not others. However modifying apache-jmeter-3.2\bin\jmeter.properties works. Tested with Win 10.

#jmeter.hidpi.mode=false
# To enable pseudo-hidpi mode change to true
jmeter.hidpi.mode=true
# HiDPI scale factor
#jmeter.hidpi.scale.factor=1.0
# Suggested value for HiDPI
jmeter.hidpi.scale.factor=2.0

1. In order to get src folder you need to download JMeter source code separately, i.e. from here. Unpack the folder and make required changes
2. You will need Apache Ant to build JMeter. Install it and make sure that %ANT_HOME%/bin folder is added to your system PATH variable

3. Build JMeter using next 2 commands:

   • ant download_jars
   • ant package

4. Now your should be able to run JMeter with increased font from apache-jmeter-2.13/bin folder like:

   jmeter -Djmeter.dialog.font=20 .....
   

   or ir you want to make font size change permanent add the next line to system.properties file (located in JMeter's "bin" folder)

   jmeter.dialog.font=20
   

   JMeter restart will be required to pick the property up. See Apache JMeter Properties Customization Guide for more information regarding JMeter properties usage.

If you trust me and Bitbucket hosting you can take the risk and get compiled binary with aforementioned change from

https://bitbucket.org/glinius/jmeter-font-increase/downloads/ApacheJMeter_core.jar

and dropping it to /lib/ext folder of your JMeter installation, however downloading binaries of unknown origin is not recommended (your PC can become a member of a botnet or someone's bitcoin mining farm) so it's better to take above 4 steps.

JMeter 4.0 update :

Before any update of Jmeter setting

After the update of Jmeter setting

JMeter 4.0 update using Windows 10 :

1. Go here : C:\apache-jmeter-4.0\bin 
2. Open to edit this : jmeter.properties 
3. Over here you need to update all required fields for you 

This is what I changed and it looks good to me :

jmeter.loggerpanel.display=true
jmeter.loggerpanel.enable_when_closed=true
jmeter.loggerpanel.maxlength=1000
jmeter.gui.refresh_period=500
jmeter.hidpi.mode=true
jmeter.hidpi.scale.factor=2.0
jmeter.toolbar.icons=org/apache/jmeter/images/toolbar/icons-toolbar.properties
jmeter.toolbar=new,open,close,save,save_as_testplan,|,cut,copy,paste,|,expand,collapse,toggle,|,test_start,test_stop,test_shutdown,|,test_start_remote_all,test_stop_remote_all,test_shutdown_remote_all,|,test_clear,test_clear_all,|,search,search_reset,|,function_helper,help
jmeter.toolbar.icons.size=48x48
jmeter.icons=org/apache/jmeter/images/icon_1.properties
jmeter.tree.icons.size=48x48
save_automatically_before_run=true


onload.expandtree=true
jsyntaxtextarea.wrapstyleword=true

jsyntaxtextarea.linewrap=true

jsyntaxtextarea.codefolding=true
jsyntaxtextarea.maxundos=50
jsyntaxtextarea.font.family=Hack

jsyntaxtextarea.font.size=28
loggerpanel.usejsyntaxtext=true
view.results.tree.max_size=10485760

Answer 4

In Jmeter 3.1 and 3.2, uncomment below lines in jmeter.properties file, and restart the Jmeter. It worked and the font size increased for all the icons and components

jmeter.hidpi.mode=true

jmeter.hidpi.scale.factor=2.0

Answer 5

Since JMeter 3.2, use Menu:

Options > Zoom In

Options > Zoom Out

See this:

JMeter 3.0 (released 2 weeks ago) has improved regarding the icons and tables but does not yet support full HiDPI mode:

See this particular bug:

• https://bz.apache.org/bugzilla/show_bug.cgi?id=58426
• https://bz.apache.org/bugzilla/show_bug.cgi?id=59168

To set properties, see:

• https://jmeter.apache.org/usermanual/hints_and_tips.html#hidpi

Now for fonts, you can use Swing mechanism. To do that, add to jmeter.sh or jmeter.bat the JVM System property:

-Dswing.plaf.metal.controlFont=Dialog-20

And ensure you use the Cross Platform LAF
