If I import a photo as a backdrop for Scratch, can I resize it to fill the Scratch screen? If so, how? Am I overlooking a piece like that used to resize sprites?

Thank you.

I encountered this same issue and got around it by using photo shop to resize the picture and then uploading the resized picture to scratch. You will need to deselect "constrain proportions"and then resize the image to 480*360 (pixels), as this is the size of a scratch background. You will lose a little image quality using this method, so if image quality is very important then this might not be the best method, but my backgrounds look fine using this method. Here's a link to a video showing this.



If you need to resize over 30 backdrops and dont have the patience, you can go to https://resizemyimg.com/multiple and, as doconnor29 said, resize them to 480 x 360.


If what you want is to upload an image to use it as background, you only have click on the small icon Upload backdrop from file on the left side of the screen under the tex New backdrop, next the sprites list. Once uploaded the edit tab will open, and with the editor you can select the image and resize it to fit the screen.

Otherwise if what you want is to resize dinamically the background during the execution of the program you'll have to create the background as a sprite with the image you want, and use the code puzzle pieces of the sprite to change the size, position and other things you want.


Here are somo screenshots: enter image description hereenter image description here

  • The only edit tab I see after uploading the backdrop from file is the one in the upper left of the screen in the "Scratch" banner. It's drop-down menu doesn't seem to enable resizing Feb 4, 2015 at 20:18

I had the same issue, and if you're using Windows like me, just follow these steps:

Open the image in the default Photos app. Click on 'Edit image' and crop the photo to 480x360 by clicking and dragging the handles at the borders of the photo.

Move the box around so as to enclose all the important bits.

Click Save (or Save as Copy if you don't want to overwrite the original).

Then simply go on to Scratch and upload the background.
