Creating button and canvas way to big

I am trying to create a new UI with a button for the first time on a 2D background. My scene is 768 x 1024 and when i create the button the canvas, and the button, is way too big. I have tried to resize etc. but i can not really get it right.

Could someone point me towards the correct way of doing this?

 

watch the tutorials! all of 'em

 

Change render mode to Screen Space - Camera and then attach your camera to it.

 

There we go, thanks.

BTW, i did check the tuts.

 

THANK YOU!

I've been following tutorials on Udemy and they never showed this, I also had little success Googling for this answer.

 

This is quite an old thread you're replying to.
There are some video's about the UI elements made by unity to explain the components.
The canvas scaler is something you may also want to look at as by default it is set to pixel reference scale 1.

As far as i know there is some overhead in the camera canvas
If set to screen overlay it may look big in the scene editor but not in the game view
I guess they chose it to be that big in sceneview to easily edit it

 

When I import my on dialog box, its transparent.. Any idea why?

 

I also had this issue. I had to update the `Sorting Layer` on the Canvas for the UI components to show up.
I added a sorting layer below everything else called UI.
