Why word length and character lengths are different?

I’m wanting to get the length of the word, as well as length of each individual character. Now, these both SHOULD equal the same amount (when adding all the character lengths together)

local WordLength = TextService:GetTextSize(
		word,
		TextSize,
		Properties.Font,
		Vector2.new(SCREEN_SIZE.X, TextSize)
	).X
	
	-- Create new TextLabel (store the word)
	local WordLabel = TextLabel:Clone()
	WordLabel.TextSize = TextSize
	WordLabel.Text = word
	WordLabel.TextTransparency = 1
	WordLabel.TextStrokeTransparency = 1
	
	-- Seperate the word into characters
	local CharPos = 0
	local i = 1

	for first, last in utf8.graphemes(word) do
		local Character = string.sub(word, first, last)
		local CharacterLength = TextService:GetTextSize(
			Character,
			TextSize,
			Properties.Font,
			Vector2.new(SCREEN_SIZE.X, TextSize)
		).X

           CharPos += CharacterLength
		
		i += 1
	end

print(word, WordLength, CharPos) --// WordLength and CharPos SHOULD be the same number

However, I get cases where CharPos is anywhere from 2-10 pixels longer than the word. This should not be happening, but I can’t figure out why it’s happening anyway.

Output example

07:49:25.297 Hello! 72 74 - Client - RichText:291
07:49:25.298 I 10 10 - Client - RichText:291
07:49:25.298 can 38 38 - Client - RichText:291
07:49:25.298 trigger 70 70 - Client - RichText:291
07:49:25.299 laugh 57 57 - Client - RichText:291
07:49:25.299 effects. 70 73 - Client - RichText:291

Most are correct, however a few go off

Are you using a monospace font?

I don’t know what that is, but I’m using FredokaOne

GetTextSize returns a Vector2 value corresponding to the amount of pixels required to store the text, which is different from the number of characters in the same given text.
