How do you make a set size for a text-label when zoomed out?

Okay, I am trying to create these ranks to go above the players head, which I have done but when I zoom out the text enlarges where as I'd like it to stay small. View pictures below to see what I mean.

I used a tutorial to help me out with it as I am still learning scripting, here's the script:

local billboardgui = game:GetService("ServerStorage"):WaitForChild("BillboardGui2")
game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
	if player.Name == "Pot8o_Penguin" then
		local clonedgui = billboardgui:Clone()
		clonedgui.Parent = game.Workspace:WaitForChild(player.Name).Head
		clonedgui.TextLabel.Text = "Owner"
		clonedgui.TextLabel.TextColor3 = Color3.fromRGB(255,116,51)
	end
	end)
end)
