Quick Answer: A standard 8-foot home pool table has an 88” x 44” playing surface, a 7-foot bar-size table measures 78” x 39”, and a 9-foot tournament table measures 100” x 50” — all following the same 2:1 length-to-width ratio, per the Billiards Congress of America’s (BCA) official equipment specifications. Every regulation table stands 29 1/4” to 31” tall at the playing surface, with corner pockets opening 4 7/8” to 5 1/8” and side pockets opening slightly wider at 5 3/8” to 5 5/8”. Below is the full spec breakdown by table size, plus what the “7-foot” or “8-foot” label actually refers to.
The number on a pool table’s spec sheet — 7-foot, 8-foot, 9-foot — never matches the table’s actual playing surface exactly, which trips up a lot of first-time buyers measuring against a room or comparing listings. This guide is a pure reference: the exact playing-surface and footprint measurements, standard height, and official pocket dimensions for each regulation size. For how much floor space each size needs to actually play on, see our pool table room size chart; for help deciding which size to buy, see our 7ft vs. 8ft comparison.
Pool table dimensions, by the numbers:
- 88” x 44” is the exact playing surface of a standard 8-foot table — the most common home size — against a 78” x 39” playing surface for a 7-foot bar-size table and 100” x 50” for a 9-foot tournament table, per BCA equipment specifications.
- 29 1/4” to 31” is the allowable range for playing-surface height off the floor on any regulation table, according to the BCA spec.
- 4 7/8” to 5 1/8” is the standardized corner pocket mouth opening, versus 5 3/8” to 5 5/8” for side pockets — the corner pocket entrance angle is fixed at 142° and the side pocket at 103°, per the BCA’s official pocket specifications.
Playing surface dimensions by table size
| Nominal size | Playing surface | Ratio | Typical setting |
|---|---|---|---|
| 7 ft (bar size) | 78" x 39" | 2:1 | Apartments, bars, tight basements |
| 8 ft (home standard) | 88" x 44" | 2:1 | Most home rec rooms |
| 9 ft (tournament) | 100" x 50" | 2:1 | Dedicated game rooms, leagues |
Every size follows the same 2:1 ratio — the playing surface is always exactly twice as long as it is wide, within a 1/8” manufacturing tolerance, per the BCA spec. That consistency is why a 9-foot table isn’t just “bigger” than a 7-foot one — it’s the same proportions scaled up, which keeps shot geometry and rail angles identical across sizes.
Why the “7-foot” label doesn’t match the playing surface
A table’s nominal size — the number on the box — describes its overall footprint, not the exact playing area. An 8-foot table’s playing surface measures 88” (7 ft 4 in), not a full 8 feet; the rails, cushions, and pocket cutouts add roughly 8 more inches to the table’s total outer length. The same gap shows up at every size: a “7-foot” table plays at 78” (6 ft 6 in), and a “9-foot” table plays at 100” (8 ft 4 in). If you’re comparing a listing’s stated dimensions against a room or a doorway, check whether the number refers to the nominal size or the actual playing surface — they can differ by nearly a foot.
Table height
Every regulation pool table’s playing surface sits 29 1/4” to 31” above the floor, measured from the bottom of the table leg, according to BCA specifications. Manufacturers pick a height within that range rather than a single fixed number — Brunswick and Olhausen’s premium slate tables tend to sit toward the middle of the range, while some budget and bar-size tables land closer to the low end. The range exists so bar stools, cue-rest height, and standard billiard-room furniture stay compatible across brands.
Pool Table Tape Measure & Leveler Set
- A 25ft+ tape measure gets the full playing-surface and footprint measurements without repositioning mid-table.
- A torpedo level checks that the table's actual height and slope match spec once assembled — useful cross-check against the 29 1/4"-31" BCA range.
- Cheap enough to keep on hand for the room-size math in our full clearance guide too.

Pocket opening dimensions
Pocket size is standardized separately from table size — the same BCA spec applies whether you’re measuring a 7-foot or 9-foot table:
| Mouth opening | Entrance angle | |
|---|---|---|
| Corner pocket | 4 7/8" – 5 1/8" | 142° (±1°) |
| Side pocket | 5 3/8" – 5 5/8" | 103° (±2°) |
Side pockets open wider than corner pockets because balls approach them from a narrower range of angles along the rail, while corner pockets need a tighter mouth to keep balls from bouncing back out on a hard angle shot. If a table’s pockets fall noticeably outside these ranges, it’s likely a non-regulation or novelty table rather than a manufacturing defect — worth checking before you assume your felt or bumpers are the problem (see our bumper replacement guide if shots are dropping unevenly for a different reason).
The bottom line
Nominal table size and actual playing-surface dimensions aren’t the same number — an 8-foot table plays at 88” x 44”, not a full 8 feet on either edge — and every regulation size follows the identical 2:1 ratio and 29 1/4”-31” height range set by the BCA. Use the exact figures above when comparing listings or checking a table against a doorway; for how much floor space you’ll need to actually play, our room size chart has the clearance numbers, and our 7ft vs. 8ft guide covers which size is the better buy for your space.
