I wouldn’t recomment you to be lazy and use a plugin, it’s actually important to understand what’s going on, and use an actual solution since converting it to scale size/position won’t fully fix the issue. The AnchorPoint property is what you should use.
The AnchorPoint property shifts the UI object by multiplying the the object’s size with itself and then subtracting it from the object’s AbsolutePosition. In other words, an anchor point of 0.5, 0 means that the object should have its position subtracted by its X size multiplied by 0.5, which shifts it to the left half its X size many pixels. More info about how the property works can be found here. I’ve also explained the calculation of it here though you need to know Lua to undestand my explanation.
