What this calculator does
Pool table room size works out minimum room dimensions so a cue has room to swing on every shot. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaRoom length/width = table length/width + 2 × cue length + 10 in (5 in of cue clearance on each side)
The inputs explained
| Field | What to enter |
|---|---|
| Table length (ft) | A number, measured in ft. Starts at 8. |
| Table width (ft) | A number, measured in ft. Starts at 4. |
| Cue length (in) | A number, measured in in. Starts at 58. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with table length
Every other input is held at the calculator’s starting values while table length varies. Select any row to load that scenario into the calculator.
