Making healthbar widgets same size regardless of distance from character

My character TestPawn1 lets you hit a key and create widget components for the enemy characters “TestChars” and then sets them to a health bar widget. My problem is that the widgets’ size will change depending on how far my character is since and don’t remain a static size on my screen like I’d like them to. Should I be scaling the UI elements an amount based on my character’s position relative to the enemy characters?

Thanks.
