Platz vs. Raum
Both Platz and Raum can be translated to the English words space or room, but they are used in different contexts based on physical dimensions and boundaries. Understanding the difference comes down to whether you are talking about an available spot or a three-dimensional volume.
Platz
The word Platz generally refers to a specific spot, a seat, a location, or a two-dimensional area needed to fit someone or something. It is used when talking about having enough physical space for an object to fit, claiming a seat, or referring to an open public square.
Ist noch Platz in deinem Koffer?
(Is there still room in your suitcase?)

(This table takes up too much space in the kitchen.)
Bitte nehmen Sie Platz und warten Sie einen Moment.
(Please take a seat and wait a moment.)

(We are meeting at the square in front of the large church.)

(He won first place in the swimming competition.)
Mach bitte Platz für den Kinderwagen.
(Please make room for the stroller.)
Raum
The word Raum refers to a three-dimensional volume, an enclosed physical room within a building, or an abstract concept of space. It is used when talking about rooms with walls, outer space, or metaphorical space such as room for interpretation.
Dieser Raum hat sehr große Fenster und viel Licht.
(This room has very large windows and a lot of light.)

(The architect used the space in this apartment perfectly.)

Summary
In short, use Platz when you need a specific spot to sit, an area to put an object, or when referring to an open public square. Use Raum when you are talking about an enclosed three-dimensional room, the vastness of outer space, or an abstract, conceptual volume.
