So in Germany, the ratio is 845 voters per place. this seems to be quite high compared to North America.

For comparison, here are the numbers in Canada for 2019 [0]:

Registered electors: 27,300,000

Polling places: 20,000

Thus, the ratio is 1365 ppl per polling place.

This is only 60% of the ratio in Germany. I am from Canada and I don't think we have any problems with voer supression.
