Accepted answer

from within eclipse:

  1. go to window > android sdk and avd manager > virtual devices

  2. select the avd you want to launch and click start

  3. check the scale display to real size button

  4. enter how big you want it to appear in inches and press launch. for this to work, you'll have to also enter a reasonable approximation of your mac's screen resolution. i'm using 7 inches and 113 dpi for my 13" macbook pro, but you may be able to get away with 8 or 9 inches.


the command to open in command prompt is given below

  1. emulator -avd [- []] ... [-]. for details see

to open a desired size emulator window follow the below command

  • emulator -avd "avd_name "-scale "scale_value"-dpi-device "dpi"


  • emulator -avd "avd_name "-scale auto -dpi-device 160/200. with dpi-device value 200

with dpi-device value 160

so just change the dpi-value according to your need. hope u enjoy.


another option would be to use the genymotion emulator, where you can actually resize the emulator window in real time. it is also much faster than the stock emulator.


you can permanently change window size of emulator by changing in config.ini file of avd

for that you need to follow this path

  • first go to your android #home directory
  • then go to .android folder
  • then avd folder and go to your avd named folder
  • you will see config.ini file

in config.ini file change the value of and skin.path to your conveniency. i have set it to 480x600 .


if you launch your emulator outside of eclipse, using the android command, you will be able to scale the screen as part of the launch process. not sure how to do that in eclipse, though.


i definitely recommend running the emulator through terminal or command line because it allows you for much better control.

for example, if you want to run emulator in different size, you just need to run it like this.

~/android/sdk/tools/emulator -scale 0.35 -avd nexus_5_api_23

nexus_5_api_23 corresponds to existing avd on my host computer. when you create different android virtual devices, you can just replace it with name of your device and it works. so basically you just run emulator from android sdk's tools directly. you can also add other parameters like netdelay, netspeed etc.


if you are working with eclipse, than here's is what you can do if the size of the emulator is too big for you screen:

  1. run > run configurations
  2. pick the "target" tab
  3. scroll down to "additional emulator command line options" and put in: "-scale 0.7" or another number

this will keep the avd scaled even if it is started automatically by eclipse.



for changing the window size of the android emulator

append the parameter -scale ­­<scale factor> to the emulator launch parameters. in eclipse, put it in the field "additional emulator command line options" within the run configuration.

allowed scale factors are those between 0.1 and 3, although the most common will probably be -scale 0.5 .


the telnet answer above is great for android studio developers. i just wanted to add that the window scale command will take either a scale factor or the dpi which may be easier for many people (measure once and it should work for you adv which are 1dp:1 pixel)

telnet localhost portnumofavd
window scale 96dpi

note telnet is not installed on windows by default anymore.


there is also a way to re size the emulator through a windows command prompt.

  1. from command prompt run: telnet localhost 5554
  2. window scale 0.75
  3. quit

assuming there is one emulator running with on port 5554.


this is actually possible from your project as well, no need to start the emulator through the avd manager:

  1. go to run > run configurations... > (select your application on the left hand side) > (click the "target" tab on the right hand side).

  2. at the bottom there, you'll see emulator launch parameters. in the additional emulator command line options, add '-scale 0.75' (to make the screen 75% of full size)

next time you start the emulator it will have scaled properly.
