There is no regulation bumper pool table size.
The Connelly Catalina pool table is an 8 foot table with 6 inch rails and 1 1/4 inch slate. The outside dimensions are 100 inches by 56 inches.
Although there is a National Bumper Pool Association in the US, they have not yet established a set of regulations for equipment and use the Billiard Congress of America rules. The BCA has no rule for bumper pool table regulation size.
Pool tables are not measured in meters. Their size is given in feet and all pool table measurements are officially in inches. Converting the inches to meters has no useful purpose as there are no meter rules that can be used for pool table dimensions of fractions of an inch. This conversion only has the purppose of a child's practice in mathematical calculations.
It was not a pool table if it only had 4 pockets if it was made since about 1800. A 4 pocket table is most likely a bumper pool table.
I wouldn't doubt it.... If height and the dimensions of an aquatic pool can be measured in centimeters, I see no reason that a table can't be...unless you're stubborn on using American Customary still.
I do not own a pool table.
It depends on the dimensions of the pool.
The actual measurement usually given is 9ft by 4.5ft, as there is nothing associated with pool and billiards that is referred to as 9ft x 5ft. And even the 9ft x 4.5ft isn't correct. A 9 foot pool table, described as 9ftx4.5ft, has outside dimensions of about 112 inches by 62 inches. This is actually very close to the 9ft x 5ft that was asked about.
As per the www.billiard-place.com, pool table lights should be hung 30" above the playing surface of the table. That way the light will not shine in your eyes and properly light up all the table.
I would hazard a guess that 7 x 4 refers, precisely, to the measurements. That could hardly be meters, centimeters, or millimeters; it is probably the dimensions of the table in feet.
