In the US, a pool ball is 2 and 1/4 inches. If you wish to measure it for wear and out of round you need to purchase a special tool or use a micrometer. To be a legal ball it cannot be out of roound by more than 0.005 inches.
The measurement of a pool table is from rail to rail on its playing surface. The common pool table sizes are 9 feet by 4.5 feet, 8 feet by 4 feet, and 7 feet by 3.5 feet.
A pool table is measured rail to rail on its playing surface. A 9 foot table is actually 100 inches by 50 inches.
You don't. There is no reason to measure it, as pool table covers are not sold that way. the only information you need is what the table size is referred to as. Such as 8 foot or 9 foot.
A 9 foot table has a 100 inch by 50 inch internal dimension of the playing surface.
The cue ball starts behind the headstring, which is an imaginary line drawn by connecting the middle diamonds between the corner and side pockets.
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 do not own a 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.
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.
Pool table in french is billard
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.
