</li>
<li>Click on the <code>Emulator</code> tab, and in the entry box <code>Additional command line options</code>, change the scale of the emulator to something of the form <code>-scale 0.X</code> (where <code>X</code> could be for example 40, if you want your emulator to be 40% of the full size)

Probably a duplicate but my step by step on what I did to get this working. 

Environment Windows 10 64-bit on Surface 3 i7 8g ram w 512g hard drive.

Run HAXM config in {android sdks}\Intel\Extra
Gave it 4 gig of ram
verified its working by going to an admin prompt and running 'sc query intelhaxm'. Status of 4 verified it was happy.

Ran Android Device manager and deleted all images present.

Created new image targeting KitKat 4.4, wqith 768mb of ram

In emulator set scale to be "4 dp to 1 px onscreen"

You'll have to experiment for your particular resolution.

Started the emulator from the device manager. Comes up FAST, and non-docked, and clickable.

I have gone through this same issue and recently got perfect solution.

While you creating your own virtual device there is an option for "Start-up size and orientation" ,the default of which is "auto"

You need to select another value according to your need from the drop-down menu and voila...

This worked for me and wish will work for you too.<a href="https://i.stack.imgur.com/xUCha.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/xUCha.jpg" alt="enter image description here"></a>

This solution is going off of what @james04 did with a minor tweak since specifying the scale as <code>-scale 0.X</code> didn't work for me.

<ol>
<li>Run --> Edit Configurations --> Emulator tab </li>
<li>Check Additional command line options</li>
<li>Type <code>-scale 128dpi</code> (or some other dpi of your choice; will need to experiment a little to get exactly what you want).</li>
</ol>

So, basically just replace <code>-scale 0.X</code> with <code>-scale XXdpi</code>.

I will give the way I did, which is different from the given methods.

Follow the steps as given :

<li>Click on Programs.</li>
<li>Select "Turn Windows feature On or Off".</li>
<li>Check "Telnet Server" and "Telnet Client".</li>
<li>Go to cmd.</li>
<li>Type "cd\" (to move to the main directory).</li>
<li>Now type "telnet localhost 5554" (leaving the quotes and the number is the same as present on top of your emulator).</li>
<li>Now type : window scale 0.x (x as per your requirement eg: window scale 0.5 to get the half screen size).</li>
</ol>

Hope this helps.

This is situational for me:
My setup:
MacBook Pro (Retina: 2880x1800) + 27' ASUS Monitor (1920 x 1080) + Startup size and orientation in AVD Manager set to Auto.

There are 2 situations in which I can start emulator:

1) With ASUS monitor attached to Macbook Pro

This results in an emulator window that fits my ASUS monitor in height. If I move the emulator window over to MacBook - it does not resize properly - part of the emulator window is hidden.

2) No monitor attached to MacBook Pro

This results in an emulator window that fits my MacBook Pro in height. This is ideal because I can now reattach the big ASUS monitor and the window is still a comfortable size.

This leads me to conclude that in the case of multiple displays - Android Studio philosophy is to pick the largest size and size the Emulator window accordingly.

So I guess Android Studio bug fix/enhancement can be to reset emulator window size based on detecting a different resolution when it is moved between displays of different resolution/dpi/ppi.

I have submitted a bug report to AOSP here:

With older versions of Android Studio, adding -scale 0.5x to the additional command line options worked like a charm.

But with Android Studio v1.5.1, The Emulator tab is missing in the Rn/Debug Configurations window.

Has anyone else encountered the same thing?

As of now, I'm starting the emulator from Command Line with the -scale option to make it work.

Starting with Android Studio 4.1, scaling the standalone emulator is not possible (or if it is, it's not straightforward), but there is a workaround:
You can configure Android Studio to run the emulator in a tool window, and, within that, the emulator adapts to the available space. If you change the tool window's view mode to &quot;Float&quot; or &quot;Window&quot; (small settings icon in the upper right) you get a fully resizable standalone emulator window. The only difference is the window frame drawn around it.
<code>Android Studio</code> -&gt; <code>Preferences...</code> -&gt; <code>Tools</code> -&gt; <code>Emulator</code> -&gt; <code>Launch in a tool window</code>
Update:
The latest version of the emulator (30.5.3) now also allows you to resize the UI when run in standalone mode. Make sure you select &quot;Show window frame around device&quot; in the emulator settings.

blocks|key|2705720|text|关于调整大小，这里有很多好的答案。但是要使用键盘移动仿真器窗口，只需按%2B空格键并使用箭头移动窗口即可。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2705721|这对任何类型的应用程序都是一个很好的技巧。|2705722|entityMap^0|Z|4|16|2|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

Concerning the resizing, there are plenty of good answers here. But for moving the emulator window with the keyboard it is as easy as pressing [ALT] + [Spacebar] and move the window around with the arrows.

This is a good trick for any kind of apps.

blocks|key|137980|text|在AndroidStudio中还有另一种方式。从底部状态栏打开端子。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|137981|输入以下内容，更改路径和avd名称以匹配您的环境。|137982|C:\android-sdk\tools\emulator.exe+-scale+0.25+-netdelay+none+-netspeed+full+-avd+Nexus_6_23|code-block|syntax|javascript|137983|备注：可根据需要调整比例|offset|length|style|BOLD|137984|entityMap^0|0|0|0|0|3|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

For those who want a cmd line way, create a shell script (this example uses window_scale.sh) in your path with this content:

<pre><code>#!/bin/bash
if [ $# != 1 ]; then
 echo usage: $0 scale
 exit 1
fi
echo "window scale $1" | nc localhost 5554
</code></pre>

Then just type the following command to resize the window to whatever you want:

<pre><code>$ window_scale.sh 0.4
</code></pre>

I ran into this issue a while ago and have been struggling for it until now. Solution seems to be:

<pre><code>Go to C:\Users\YourUser\AppData\Local\Android\Sdk\emulator
</code></pre>

Here, right click on <code>emulator.exe</code>, 
click <code>Properties</code> and go to <code>Compatibility</code>. Here, check: "<code>Override high DPI scaling behavior. Scaling performed by: APPLICATION</code>".

This should fix the issue on any Windows 10 machine with display scaling activated.

I've seen many posts asking about how to re-size the AVD emulator window, however I have not found any that work. My emulator is off the top of my computer screen, and I cannot resize it.
