Hi Muuthy,

You can change the canvas size by clicking the "Settings" button beneath your program.

Then, select the size you want and click Save. Once you change the size you will need to reload the page.

Hi Muuthy,

As far as I know, you can add ?height=300 to the end of the URL to do what you want. Sadly, Khan Academy does not support sizes smaller than 400, so you'll have to change the ratio by making the program wider. Adding ?height=800 to the end of the URL will give your program the same ratio as ?width=200.

That's fine for me! I just needed to make the canvas the size of a tv. (Width longer than height.) Thank you!

But how do you change the width and the height together? I can only change either the width or the height.

?height=800&width=800 would set both to 800.

Can someone please help?
I also need to change the size of my Canvas but there is no setting option here:

aldila.widyastuti You can only change the canvas size on your own projects. i.e. the project needs to say Created by: Your Name beneath it for you to be able to see the settings button.

If you want to change the canvas size on a challenge in the courses, you'll need to make a spin-off of the challenge first.

Evan Lewis I figured it out. Thank you for your help! :)
