Screen Size [WHICH MORE ACCURATE]

[robloxjw02 (TheRaven)]

local function getDeviceScreenSize()
	local X = game.Workspace.CurrentCamera.ViewportSize.X
	local Y = game.Workspace.CurrentCamera.ViewportSize.Y
	local Result = ('%d , %d'):format(X, Y)
	return Result
end

local function getDeviceSize(Gui)
	local size = Gui.AbsoluteSize
	local X, Y = size.X, size.Y
	local Result = ('%d , %d'):format(X, Y)
	return Result
end

print(getDeviceScreenSize())
print(getDeviceSize(script.Parent))

Because it has different results, even though it’s so slight.

Is the getDeviceSize(Gui) getting the gui minus the topbar that appears (the inset)? If so then i would assume the larger is more accurate but i guess it depends on what you are trying to achieve.

Edit: upon reading the API it looks like i was right as the inset is 36 pixels…your difference.

There is always a 36 pixel gap for the Roblox TopBar like @RMofSBI said.

I prefer to use game.Workspace.CurrentCamera.ViewportSize as it’s the easiest to index but it’s all preference.
