Hi,

Can I make a circular button which has the diameter of 50% of screen width?

I know how to make a circular button, using radius.  
I know how to make the width 50% of screen.  
I don’t know how to make the **height** = 50% of **width of screen.** or how to _lock_ one dimension to the other.

Is it possible?

Thanks for reading ~

Use the block to get the screen width and then divide this value by 2

Aha, ok, thank you. I don’t know yet how to do that, but sounds like I’ll be able to figure out.
