Size of panel to access house trap

I am installing a new bathroom as part of a basement finishing project. The house trap is located behind one of the bathroom walls, right next to the toilet. I know I need to leave access to that trap, but I'm not sure how big the access panel should be. I've never needed to take off one of those trap plugs, so I don't know how much room is needed to work there. I'd like the panel to be as small as feasible, but I don't want to screw myself later by using a too-small panel now.

Any suggestions as to the recommended size of the access panel is appreciated.

Not seeing it makes it difficult to comment. But as a good rule, imagine your are the plumber and you have to snake it. Get a garden hose and determine how much area you will need to shove it into the pipe end. This will give you a good indication as to the location, angle and size of the opening.

I don't know if it applies or not but I've worked on jobs where the access for tub motors [whirlpool,jacuzzi] was 16"x16" minimum dictated by code.
