Size of the mulberry plane tree , here is the question of a user:
Pictures speak louder than words, so the ones below should help. Nevertheless, the small branches are to be eliminated. Only the extensions of the carpenters and certain new shoots are kept. They are reduced to around 20 to 30 cm (or even 50 cm) and just after a bud located at the bottom or at least towards the outside of the tree. I would add that in some cases, if the tree has sun damage to the top of the trunk or the base of the struts, the pruning will be less severe in order to keep as much shade as possible in the injured places.
I hope I have helped you in your search. Be careful if you climb the tree, the mulberry tree has brittle wood.
Here are two before / after photos.

Size is not an exact science. Nevertheless, even if there can be discussion on the short or long size, there are still some rules to respect. The size must be clean for better healing. Cut 2 or 3 cm after a bud. Closer, the bud is weakened. Longer, there is a piece of branch that will dry out and possibly harbor pathogenic fungi. Pruning tools should be disinfected so as not to spread disease.
The thinner and almost horizontal branch in the photo below could have been removed. But according to its place, and its future (development of the bud) it can either bring beneficial shade to the base of the carpenters, or develop where there is a lack of branch. You can see that size is not an exact science!
