TextFits is false on mobile device

For a specific animated text effect, I need to create an individual text label for each grapheme. I do this very simply: for each grapheme, create a label using a predetermined text size and sizing the label based on label.TextBounds.

Code for creating TextLabels 
for first, last in utf8.graphemes(newText) do
	local character = string.sub(newText, first, last)

	local container = script.LetterTemplate:Clone()
	local label = container.TextLabel

	label.Text = character
	label.TextSize = chosenTextSize

	container.Name = tostring(first)
	container.LayoutOrder = first
	container.Parent = hintFrame		
	container.Size = UDim2.fromOffset(label.TextBounds.X, label.TextBounds.Y)
	
	label:GetPropertyChangedSignal("TextBounds"):Connect(function()
		container.Size = UDim2.fromOffset(label.TextBounds.X, label.TextBounds.Y)
	end)
end

In almost all use cases, this works exactly as intended. Both on PC (in-studio and in-game), and on the mobile emulator in studio, this functions correctly. However, upon testing in-game on a mobile device (iPhone 15 Plus), “TextFits” is false for some of the created labels.

Any idea what may be causing this and how I might be able to fix it?

#2

Use Scale instead of Offset and it will automatically scale the UI based on the screen resolution.

#3

I don’t need the UI to scale based on the screen resolution, I need the UI to scale specifically to the minimum rectangular dimensions of the grapheme.

By grapheme do you mean letter?
