Sub panel recommendation

I'm finishing my basement and determined that I need a subpanel because I only have 3 slots left in my 200a main panel and I have 7-8 more circuits to install to complete the basement.

Those 7-8 circuits are:

2 - 20a circuits for wetbar recepts (GFI) and home theater
5 or 6 - 15a circuits (AFCI) for recepts and lighting for office, and other rooms

I plan to use two of the remaining slots in the main panel for the breaker that will feed the subpanel, but I'd like to know recommendations on what size subpanel (60 amp or larger?), and what size corresponding breaker to feed the subpanel? I have some extra 8-3 and 6-3 wire leftover from another project, and the subpanel will be able to be located right beside the main panel in the basement panel room.

Also, if possible given everything mentioned above, I'd like to have 2-3 slots left over for any future expansion just in case.

Let me know if I'm leaving any necessary info out.

Thanks!!

I'd put a 100a panel in
Then you can feed it with #6 & use a 60a breaker ($17 maybe)
If you need heavy duty power then feed it with 100a breaker (53?)

Like scuba said, put in a 100 amp main lug panel, feed it with a 60 amp breaker and use the 6/3.
Make sure to get a ground bar for the sub and seperate the ground and neutral wires.

Search "sub panels" on this forum for further information if needed. There many, many threads on this topic.

Just to be clear

You need to use different wire if you are going to feed it with 100a
The #6 is good for the 60a 240v
