Amsterdam has old trams and new trams. The older trams are not all accessible, with higher entrances, staircases and narrow paths inside. One middle carriage has a lowered floor for wheelchair access.
The new trams have wider, accessible entrances marked with a wheelchair icon on the carriage door. The tram conductor can assist you with a fold-out ramp for easier entry and exit. The need for the ramp will depend on the tramp stop. Certain stops have a large height difference between the pavement and tram floor, while others are almost equal in height.
