How long a ramp is needed for a 2 step entrance?

Excuse me, could you please clarify the specifics of the entrance you're referring to? Are we discussing a ramp for accessibility purposes, or is it a matter of aesthetics? Additionally, could you provide some more context, such as the dimensions of the steps and the intended users of the ramp? This information would greatly assist in determining the appropriate length of the ramp required for a two-step entrance.
