What's the Difference Between Pool and Billiards?

Why This Question Is So Confusing

The short answer is that the words 'pool' and 'billiards' mean different things in different places, and none of the definitions are wrong, they just reflect how language evolved separately in different countries. An American, a Brit, and a Belgian could have a conversation about 'billiards' and each mean something completely different without realizing it.

I run into this with international players all the time. An email from a guy in Antwerp saying he plays 'billiards' probably means 3-cushion carom, not 8-ball. A British pub regular saying 'billiards' often means English billiards, a specific three-ball game played on a snooker table. An American saying 'I played billiards last night' almost certainly just played pool. Context is everything.

The American Usage, Pool Is Pocket Billiards

In the United States, 'pool' almost always means pocket billiards, any cue game played on a table with pockets, where the goal is to pocket balls. 8-ball, 9-ball, 10-ball, straight pool, one-pocket, bank pool, and their variants all fall under 'pool' in American usage. The word 'billiards' in America is used more formally or ambiguously, it's the umbrella term for all cue sports.

So a sentence like 'the Billiard Congress of America' uses 'billiards' as the umbrella, even though the BCA's main focus is what Americans call pool. The official name of 9-ball is 'pocket billiards' in formal rulebooks, which is why 'pool' and 'billiards' often appear to be used interchangeably in American contexts.

If you're in America and someone asks 'want to play billiards?' they almost certainly mean pool. If they specifically want to play a pocketless carom game, they'll say 'carom' or '3-cushion' by name.

The International Usage, Billiards Often Means Carom

In most of continental Europe, South America, and parts of Asia, the word 'billiards' (or its local equivalent like 'biljart' in Dutch or 'billar' in Spanish) specifically refers to carom billiards, the pocketless three-ball games like 3-cushion, balkline, and straight rail. What Americans call pool is called by other names: 'pocket billiards,' 'American pool,' or sometimes just 'pool' as an English loanword.

This is why international cue sport associations often split 'pool' and 'billiards' into separate governing bodies. The Union Mondiale de Billard (UMB) governs carom billiards worldwide. The World Pool-Billiard Association (WPA) governs pocket billiards. The World Snooker Federation governs snooker. Three distinct worlds with overlapping terminology.

In Belgium, where carom billiards is the dominant cue sport, the word 'billiards' without qualification almost always means carom. An American transplant who asks a Brussels cafe for 'a game of billiards' will get pointed to a pocketless table and handed a carom cue. It's a common source of polite confusion.

The British Usage, English Billiards Is Its Own Thing

The United Kingdom has its own specific game called 'English billiards,' played on a standard 12-foot snooker table with just three balls: a red, a white cue ball, and a yellow cue ball (or white with spot). Players score points through pots (pocketing balls), cannons (caroms off both other balls), and in-offs (pocketing their own cue ball off another ball).

English billiards was once the dominant cue sport in the British Empire, but snooker overtook it commercially in the mid-20th century. Today it's still played at amateur and some professional levels but is a niche interest. Importantly, English billiards is what a traditional British person might mean by 'billiards' without qualifier, not snooker and not carom.

British pubs also have 'pool,' which is typically English 8-ball pool, a variant of 8-ball played on a smaller table with red and yellow balls instead of solids and stripes. English pool has its own rules quirks and is genuinely a different game from American 8-ball, though the core is the same.

Where Snooker Fits In

Snooker is considered its own discipline separate from pool and billiards in almost every country. It has its own governing body (World Snooker Federation), its own tables (12 feet, tighter pockets), its own balls (52.5 mm, 15 reds plus six colors), and its own professional tour. When someone talks about 'snooker,' they always mean snooker specifically.

The confusion arises because snooker tables can also be used for English billiards, it's the same table. So in the UK, a snooker hall might host both snooker and English billiards games on identical tables. But the two games are distinct: snooker has 22 balls, English billiards has 3.

In America, snooker tables are rare and snooker itself is a niche pursuit despite being hugely popular in the UK, China, and across much of Asia. Top snooker players like Ronnie O'Sullivan and Judd Trump are global stars in those markets.

A Practical Guide for Travelers

If you're traveling internationally and want to play, here's a simple rule: always ask what kind of table is available before using either word. 'Do you have pool tables with pockets?' works in almost every country and clarifies exactly what you want. Asking for 'billiards' without qualifier can get you anything from 3-cushion carom to English billiards to American pool depending on where you are.

In Belgium, Netherlands, Germany, France, Spain, Italy, Turkey, assume 'billiards' means carom by default. In the UK, assume it might mean English billiards. In the US, Canada, Australia, and most of Latin America, 'billiards' and 'pool' are used interchangeably and you'll get a pocket table.

When in doubt, the words 'pocket billiards' or 'American pool' are universally understood to mean what Americans call pool. Those phrases travel better than the bare word 'billiards' anywhere outside the US.
