How to Measure a Pool Table

Why the Measurement Matters

Most of the time people ask me how to measure a pool table, one of three things is going on: they are buying a table and want to confirm the size, they are buying a cover or cloth and need exact dimensions, or they are planning a room and want to know if a table will fit with enough cue space. In all three cases, getting the measurement right saves you a lot of money and heartache.

Here is the part that trips most people up: pool tables have two dimensions, and they are very different. The playing surface (the cloth area inside the rails) is what determines the official size of the table. The outside dimensions (the outer edges of the rails) are what determine whether it will fit through your door. Confusing these two is the single most common measurement mistake.

Playing Surface Dimensions

Playing surface is measured from the nose of one end rail to the nose of the opposite end rail, and from the nose of one side rail to the nose of the opposite side rail. The 'nose' of the rail is the point where the cushion rubber meets the cloth surface. This is the actual playable area where balls roll. Standard pool table dimensions in the US are based on playing surface, not outside size.

The playing surface is always twice as long as it is wide. This is a BCA (Billiard Congress of America) specification and it holds for every regulation table. A 7-foot table has a 39 x 78 inch playing surface. An 8-foot table has a 44 x 88 inch playing surface. A 9-foot table has a 50 x 100 inch playing surface. If the table you are measuring is not exactly 2:1, it is either not regulation or you are measuring wrong.

The Standard Sizes

The 7-foot table, also called a 'bar box,' is the smallest standard size and is what you will find in most bars and pubs in the US. Playing surface is 39 x 78 inches, outer dimensions roughly 46 x 84 inches. It is fast-paced and forgiving on beginners because balls are closer together and pockets are relatively larger compared to the table.

The 8-foot table is the most common home size. Playing surface is 44 x 88 inches, outer dimensions roughly 52 x 96 inches. Some manufacturers make an 'oversized 8' at about 46 x 92 inches playing surface; it sits between the standard 8 and the tournament 9. The 9-foot table is the tournament standard. Playing surface is 50 x 100 inches, outer dimensions roughly 58 x 108 inches. Almost all televised professional matches use 9-foot tables with tight pro-cut pockets.

Step-by-Step: Measuring Rail-to-Rail

Grab a measuring tape at least 10 feet long. Place the end of the tape against the nose of one end rail, right where the cushion rubber meets the cloth. Stretch it straight across the table to the nose of the opposite end rail. That is the long dimension. Do the same for the shorter side, nose to nose on the long rails. Those two measurements are your playing surface. Round to the nearest inch.

If the long dimension is around 78 inches, you have a 7-foot table. Around 88 inches, an 8-foot. Around 100 inches, a 9-foot. If your numbers are between those values, double-check that you measured nose-to-nose and not over the rails. Measuring from outer rail to outer rail will give you roughly 6 to 8 inches more than the playing surface dimension, which is where people get confused and call their 8-foot table a 9-foot.

Outside Dimensions for Moving and Fitting

When you need to know if the table fits through a door or on a truck, use outside dimensions. Measure from the outermost edge of one rail (the wood part, not the cushion) across the table to the outermost edge of the opposite rail. Then do the same for the shorter side. Also measure table height (floor to top of rail); most tables are 30 to 32 inches tall.

Doorways and hallways are the usual obstacles. A standard interior door is 30 to 32 inches wide. An 8-foot table's 52-inch outer dimension will not fit through sideways, but because tables come apart for moving (rails detach, slate separates into three pieces on a slate table), this rarely matters for pre-assembled moves. Still, measure your doors and hallways before you commit to a table you cannot get into the room.

Room Clearance: The 5-Foot Rule

You need 5 feet of clear space on every side of the table for cue strokes. This is the universal BCA recommendation and it accounts for a 58-inch cue plus follow-through plus comfortable body position. If you do not have 5 feet on every side, some shots will force you to use a shorter break cue or a push-stick, which is awkward and unprofessional-feeling.

So an 8-foot table with outer dimensions of 52 x 96 inches needs a room that is at least 52 + (5 ft x 2) = 52 + 120 = 172 inches wide (about 14 feet 4 inches) and 96 + 120 = 216 inches long (about 18 feet). Smaller rooms can host a smaller table: a 7-foot table's 46 x 84 outer fits in roughly 13 feet by 16 feet of space. Measure your room before you buy the table, not after.

Odd Cases: Unusual Tables and Non-Standard Sizes

Some older tables, antique tables, or custom tables do not hit the standard 7/8/9 sizes exactly. A true antique might have a 39.5 x 79 inch playing surface. Some European pocket billiards tables run 10-foot or even 12-foot. Snooker tables are 12 feet and use much smaller pockets and balls; do not confuse a snooker table for a pool table by eyeballing it from across the room.

If you have measured and the numbers do not match any standard, the table is either custom, antique, or mislabeled. For cloth orders and table covers, always order to your actual measured dimensions plus 6 to 8 inches of drape. For league or tournament play, the table must match a standard size; non-standard tables cannot be used for sanctioned matches.
