Rasters don't really have a scale, they have a resolution, which in your case is 200m. You can calculate an appropriate viewing scale for a given raster resolution based on the ability to distinguish features.
The ArcGIS Blog post On map scale and raster resolution discusses this:
In 1987, Waldo Tobler, renowned analytical cartographer (now emeritus from University of California-Santa Barbara) wrote, “The rule is: divide the denominator of the map scale by 1,000 to get the detectable size in meters. The resolution is one half of this amount.”
So here is the appropriate resolution for a select set of map scales:
For example, if you were not sure what resolution imagery you needed to acquire to detect features at a map scale of 1:50,000, using Tobler’s rule above, you can determine that imagery of approximately 25m [50000/ (1000*2)] resolution would be sufficient.
Similarly, if you need to find out the mapping scale from a known imagery resolution you can do so using the formula below:
Map Scale = Raster resolution (in meters) * 2 * 1000
Two, as used in the equation above, doubles the resolution. Then that number is multiplied by 1000 to get the map scale.
Here’s an example. Say you have a raster with a resolution of 30 meters. Each pixel is 30 meters on a size (an area of 900 square meters). You double that to get four pixels (two rows and two columns) with a resolution of 60 meters on a size (an area of 3600 square meters). Then you multiply that 60 meter resolution by 1000 to get a map scale of 60,000.
