It's the cue, not the table.

The rule

Room = playfield + a full cue's stroke on every side. A standard cue is 58″; our clearance halo uses 60″ so the back-swing keeps its knuckles. Measure from the playfield (the cloth inside the rails), not the table's outer edge.

Room sizes by table

The short-cue compromise: a 48″ cue on the tight wall buys back about a foot per side — livable for the odd rail shot against one wall, miserable as a way of life on two. If the room is more than one cue-length short, buy the smaller table.

The rest of the rec room

Run the arithmetic yourself

One line, and it works for any table and any cue:

room = playfield + (2 × cue clearance), on each axis.

Our halo uses 60″ from the playfield — a 58″ cue plus a couple of inches so the back hand keeps its knuckles. Worked on a tournament 9-footer, whose playfield is 100 × 50: 100 + 60 + 60 = 220″, or 18′-4″, and 50 + 60 + 60 = 170″, or 14′-2″. That is the whole calculation. Every published room chart is this sum with a different assumption about the cue, which is why charts from different manufacturers disagree by a few inches and none of them is wrong.

The datum is the part people get wrong, and it costs about a foot. Measure from the playfield — the cloth inside the rails — not from the table's outer edge. On a standard 8-footer the outer dimensions are 103 × 58″ and the playfield is 92 × 46″: that is 11 inches of length and 12 inches of width of difference, in the direction that makes you buy a table which does not fit.

Worked the other way: what fits a 15 × 15 basement? Fifteen feet is 180″. With a full cue you have 180 − 120 = 60″ of playfield to spend, and the smallest standard playfield is the 7-foot bar box at 78 × 39 — so the answer with full cues is nothing. Drop to a 48″ short cue and the sum becomes 78 + 96 = 174″ (14′-6″) by 39 + 96 = 135″ (11′-3″), and the bar box fits with room to spare. That is the honest verdict for most basements: a smaller table, or short cues, and knowing which before the delivery rather than after.

The things that are not on the floor plan

• The corner shot is the one you lose first. A wall that is a foot short does not cost you a foot of play — it costs you every shot that has to be taken from that direction, which is a quarter of the table.
• A short cue on one wall is livable; on two it is a hobby you stop having. If the room is more than one cue-length short, buy the smaller table.
• Doorways and stairs come before the room. A slate table arrives in pieces — the slate itself in two or three slabs — and the frame does not. Check the stairwell and the turn at the bottom before you check the room; a table that cannot get downstairs never needed the cue math.
• Slate is a floor-loading question in a basement conversion only rarely, and on an upper floor almost always. Ask before, not after.
• The light hangs low over the cloth and it is not optional if you want to see a ball near a rail. Manufacturers publish a mounting height for their own fixture and that is the only figure worth using. A ceiling fan over a pool table is a lost ceiling fan.
• Cue racks, a scoreboard and somewhere to stand all live outside the cue halo. The halo is the play zone, not the room.

Common questions

What size room do you need for an 8-foot pool table?

Take the playfield — 92 by 46 inches on a standard 8-footer — and add a full cue's clearance on every side. Our halo works from 60 inches off the playfield, which puts the room a little over 17 feet by nearly 14. The table's own outer dimensions of 103 by 58 are not the number to use; measuring from the rails instead of the cloth costs you about a foot in each direction, in the wrong direction.

Can you fit a pool table in a 15 by 15 room?

Not with full cues. Fifteen feet is 180 inches, and 60 inches of cue clearance on each side leaves only 60 inches of playfield to spend — less than the smallest standard table, the 7-foot bar box at 78 by 39. With a 48-inch short cue the sum becomes 78 plus 96, or 14 feet 6, and the bar box fits comfortably. So a 15 by 15 room takes a 7-footer if you accept short cues on the tight walls.

How much space do you need around a pool table?

A full cue's stroke on every side. A standard cue is 58 inches; our clearance halo uses 60 so the back swing keeps its knuckles off the wall. Measure it from the playfield, not from the table's outer edge. A 48-inch short cue buys back about a foot per side, which is a reasonable compromise against one wall and a miserable way of life against two.

Is a 7-foot or 8-foot pool table better for a home?

Whichever one the room takes with a full cue. An 8-footer is the standard home table and plays closer to how a 9-foot tournament table plays, but it needs the best part of 18 by 14 feet of clear floor. A 7-foot bar box needs about 16 feet 6 by 13 feet 3 and is the honest answer for most basements. A cramped 8-footer is worse than a comfortable 7.

Do you measure a pool table from the rails or the playing surface?

From the playing surface — the cloth inside the rails — because that is where the cue ball is and where your cue has to come back from. On a standard 8-foot table the outer frame is 103 by 58 inches while the playfield is 92 by 46, so measuring the wrong edge understates the room you need by about 11 inches of length and 12 of width. Every published room chart assumes the playfield.
