Some very yeshivish families have more than 10 kids, I have seen ranging from 11-16. Some Chassidish families will have less and keep it there (like seven or less and no plan on having more).
Chassidish families are less likely to be so into the idea of kollel support to the extent that they are in the yeshivish circles.
The process of being set up is different. In order to get a shidduch in the Chassidishe velt, someone who has enough information about you like = to vetting through end of third date in litvishe velt, has to vet for you. Shidduch resumes have to have at least 10 references and the beshow thing.
Yeshivish is dating oriented. But both litvish and chassidishe have shidduch resumes and see shadchanim themselves.
In the chassidishe velt there is a bit more of a drastic caste system. BT is either expected to marry a BT or someone from a non-chassidishe FFB background. If you are a BT and look for a Chassidishe FFB from Chassidishe family, you will find yourself with someone who has a disability such as needing a wheelchair, or undisclosed bipolar… something like that. Some chassidim go on dates in addition to beshows.
Yeshivish also has somewhat of a caste system, but people do not think about it as much. Basically, if you have been frum less than five years people may do a more deep search into you. But if your dating, you can break up with someone more easily than with a Beshow. Yichus with yichus and so on.
