How to Resize Bluestacks Resolution?

Perhaps Bluestacks is one of the most famous and popular Android emulator allowing you to run applications for this mobile platform on PC and Mac without having to install a fully virtual environment of Android. Using Bluestacks App Player you can play any Android apps on your computer. A very serious drawback of Bluestacks is the lack of such basic settings as changing the screen resolution, the amount of RAM used. However, these settings can be changed using small registry tweaks.

Bluestacks resolution is one of the things which is to be resized and changed when required. In this tutorial, we will show you how to change Bluestacks resolution in Windows or how to resize Bluestacks on your computer. Follow the below steps carefully.

How to Change Bluestacks Resolution?

If you don’t have Bluestacks installed in your Computer, download it from official website.

The BlueStacks resolution determines what width and height in pixels the running game will have in full screen mode on your monitor.

    There is also Portrait (Phone mode) and Custom, in which you can set your resolution if it is not in the list presented by the program. bluestacks change resolution
  4. Restart BlueStacks.

Change Bluestacks Resolution via Windows Registry

  1. Open Windows Registry Editor by press Win+R keys and type regedit;
  2. In the left pane expand the following registry key: HKEY_LOCAL_MACHINESOFTWAREBlueStacksGuestsAndroidFrameBuffer
  3. 9 rows of values appear in the right column. We are interested in only four of them: WindowWidth, WindowHeight (describes the width and height of visible window); and GuestWidth, GuestHeight (Guest window sizes or resolution in Android);
  4. The size of the window (WindowWidth and WindowHeight) determines how much space the emulator window will occupy on the screen. If at this moment it takes all the possible place on the Desktop, then we will not increase these parameters (in our case WindowWidth=1680 (decimal), WindowHeight=1050(decimal), but you can increase/decrease this value if need);
  5. It often happens that you need to change the internal emulator resolution. Increase the values of GuestWidth to 1680 and GuestHeight to 1050 (depending on your screen resolution);

  6. As a rule, the internal and external resolution of the window must coincide;
  7. Restart the BlueStacks emulator by clicking on the tray icon and selecting Exit. Then run the BlueStacks again and check new resolution;
  8. If the screen resolution does not suit you, again change the value of registry parameters described above.

If you need to change the amount of RAM available to BlueStacks, open the registry key HKEY_LOCAL_MACHINESOFTWAREBlueStacksGuestsAndroid and change the value of Memory parameter. Here you need to specify not more than half of the available physical memory of your computer (in MB). There is also a graphical way to do this in the program settings in the “Engine” section.

After making the changes, you must restart BlueStacks. Please note that the program limits the allocation of RAM for it in order to ensure the stability of Windows. In any case, do not overdo it with this value so that the system does not depend on lack of memory.


  1. after changing the window size and trying to reopen the bluestacks, it shuts down suddenly and when i open it again it returns to the old size .

    please note that i am using clashbot .. waitng ur answer

    1. Hi Mahmoud,
      This problem is usually faced by allot of people. You have to uninstall the Bluestacks and download the latest version available. This will solve your problem.

  2. Thank you! Worked great. I have two monitors that are different sized, and I sometimes want to run BlueStacks on my secondary monitor, worked great so I can fit it into either one I want to use!

  3. Hi !
    How I can Ajdust the Size of BlueStacks To Note 4…It’s Currently looking like a Tablet Mode, Or is there any way To Change The Display To look like Mobile Display

    1. Hi Sweetu,
      You can adjust the size as per your requirement. Look for the Note 4 display resolution over the internet and apply the measurement as applicable.

  4. Hey Aman,
    i use BSP on W8. I changed the size of the Player. That works perfect.
    Where can i change the size from apps like Line?
    So i cant find something in the settings. May the Player doesnt provide such things as W8 player?
    Thanks in advance for your help 🙂

  5. I’ve put 1440×900 and now the screen is blurry. I tried to rise GuestWidth and Height to match 1440×900 but it doesn’t work either, guest area remain smaller than Window and clicks are misplaced.

  6. I have tried to do the adjustment on a windows linx tablet. No matter what size I put in, the bluestack app resorts to a thin narrow version of e.g. wats app, I only downloaded blue stacks 2 weeks ago….

  7. How do I save these changes. Every time I go back to see what’s the resolution it goes back to the default settings.

  8. I found this very helpful. I did not have this problem with Bluestacks 1, but when I upgraded to BlueStacks 2 I have to readjust the window size every time I open the program. I am not sure if this problem keeps occurring because I have to adjust my window size? But without changing my registry my display is very distorted. My monitor is optimal at 1920×1080 and I believe that is what Windows 10 is set to.
    Is there a way for me to default the settings I input?
    Thank you very much!

  9. Once bluestacks loads, the menu is massive. I can’t scroll and can only see a few icons. Changing resolution didn’t help the menu. This randomly happened, no idea why everything became so massive. Thoughts?

  10. I too am having no joy with this fix, tried your 1024 x 600 setting and my 1680 x 1050 and nothing at all are you able to assist please

  11. I use the most recent version of Bluestacks and I’ve been trying to play Sword of Chaos. When it loads it has a video and after said vid it’s seriously zoomed in to the point that all I can see I’d the start button. I’ve used your guide on the resolution with some success but I still can’t get the right inch of the game where all the buttons are. Is there a regedit entry to default an app to the size of the Bluestacks screen?

    1. Hey, Ben!

      Try to test the following resolution settings:
      WindowWidth = 1024
      WindowHeight = 600

      If above values didn’t help, try one of these combinations:

  12. Hello to all,
    Bluestacks takes up 1.5 GB on my drive. I only run ColorNote – no games. ColorNote only needs about 20 MB for the app & data.
    What can I do to reduce these 1.5 GB ??

  13. i figured out a better way for this. using autohotkey i wrote this script: RegWrite, REG_DWORD, HKEY_LOCAL_MACHINE, SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0, GuestWidth, 900

    all i needed to do was change my guestwidth for playing railrush. you can modify that script’s values and use it yourself. also to change it back i wrote the same script but replaced 900 with 1280. try that out.
