I’ve posted about pocket size a lot and what Iike. If you have a home pool table, put 5.5” corner pockets if you wanted.
It’s for your personal pleasure. You can put in 4.25” pockets. When it is your table, install as big or small as you prefer.
Personally, 5” CP seem too big but for so for some, maybe 4.75” is better suited instead of 4.5” for a home table. Pool
room operators have to decide what to offer. It seems 4.5” is becoming more common with so many Diamond tables
populating pool rooms. Sierra Billiards, where I mostly play, the 9’ tables are evenly split with 4.25” and 4.5” CP sizes.
