Any rules of Thumb for "safe" ratio of attacking forces?

Hi, I'm a new player and trying to get a sense of what ratio of attacking to defending forces is required in order to have some confidence in a successful attack. For example, is a 2:1 ratio (or some other ratio) of attacker's total attack value to defender's total defense value required to easily take a city? I'm assuming you also need to take into account any unit- and strategy-based bonuses that apply to the given battle?

After you made a move to attack a city, simply hower over it and you will see your attack/def and your opponents attack/def.
strategies might affect this and ofc a player might put new units into the city but pretty much as long as attack is higher it should take a city

Wrong attack should not be used as the only factor. Often you will fail horribly if you rely on attack numbers.
