Is there a good way of determining the convolution filter size, or should we experiment in each case?

It depends on the goal, but with the box filter the larger the filter size, the more the resulting image is smoothed. Here are some slides about this from CS131 (starts on slide 34) => http://vision.stanford.edu/teaching/cs131_fall1819/files/03_filters.pdf
