Beginner question on relative sizes of text elements on a canvas

Hi,
I’m sure that this is really simple but I cannot find a solution and I am a complete beginner.

In the scene editor I created a very simple 2d scene with a canvas and inside it some text boxes.
The textboxes are TextMeshPro objects.
I would like to set one textbox to be 20% of the width of the canvas and 50% of the height of it, and to keep these proportions if I change the dimensions of the canvas.

To do this, in the Anchors presets I select the “stretch” option and put the anchors to the corners of the parent canvas. Then I set the X scale to 0.2 and the Y scale to 0.5. This method seems to work but the problem is that also the text is scaled both in the X and Y directions and it looks weird.

Is anyway to avoid the scaling of the text or is any other method to achieve what I need?

Thanks for your help

Yes, your approach is incorrect.

Put the X and Y scale of your object back to 1. The correct way to do this is to explicitly set the anchors. For example, set your X min to 0 and X max to 0.2, which makes it 20% the width of the parent (and positioned on the left). For 50% the parent height, you’d set Y min/max to 0 and 0.5 (or 0.2 and 0.7, or whatever else you like). Set your Left, Top, Right, and Bottom all to 0, and Bob’s your uncle.

Thanks, It works!
