Choosing a pool cue case is not only about the material, color, or design.

One of the first things you should consider is capacity.

If you have ever searched for a pool cue case online, you have probably seen terms such as 2B3S, 2B4S, 3B4S, and 3B6S.

But what do these numbers actually mean?

More importantly, how do you know which pool cue case size is right for your equipment?

In this guide, we will explain the differences between 2B3S, 2B4S, and 3B4S pool cue cases and help you choose a configuration based on the cues and shafts you actually carry.

---

What Do 2B3S, 2B4S, and 3B4S Mean?

The numbers used to describe a pool cue case usually refer to the number of cue butts and cue shafts the case is designed to hold.

For example:

• 2B3S = 2 cue butts + 3 shafts
• 2B4S = 2 cue butts + 4 shafts
• 3B4S = 3 cue butts + 4 shafts
• 3B6S = 3 cue butts + 6 shafts

The exact internal construction can vary between manufacturers, so always check the specifications of the individual case.

However, this terminology gives you a quick way to compare different pool cue case configurations.

2B3S Pool Cue Case: Compact and Practical

A 2B3S pool cue case is designed for players who need more capacity than a basic single-cue case but do not want to carry a large case.

A typical setup might include:

• 1 playing cue
• 1 break cue
• 2–3 shafts
• Essential accessories

This configuration can work well for:

• League players
• Regular pool hall players
• Players with a relatively simple setup
• Players who prioritize portability

If you normally carry only one playing cue, one break cue, and a few shafts, a 2B3S case may provide enough room without adding unnecessary bulk.

When should you choose 2B3S?

Consider a 2B3S pool cue case if:

• You have two cue butts
• You need up to three shafts
• You do not carry a jump cue
• You want a relatively compact setup
• Most of your playing is local

The key advantage is simplicity.

You get dedicated storage for your essential equipment without moving into a larger tournament-style configuration.

2B4S Pool Cue Case: More Shaft Capacity

A 2B4S pool cue case keeps the same two-butt capacity but provides additional room for shafts.

This can be useful if you have multiple shafts for your playing cues.

A possible setup could include:

• Playing cue
• Break cue
• Primary shaft
• Backup shaft
• Additional shaft
• Spare shaft

For players who have invested in multiple shafts, the additional storage can make a noticeable difference.

Instead of putting extra shafts into an unsuitable compartment or carrying another case, a 2B4S configuration gives you more dedicated space.

Who should consider a 2B4S case?

A 2B4S pool cue case may be suitable if:

• You carry two cue butts
• You use several shafts
• You want more flexibility than a 2B3S
• You play frequently
• You want additional equipment capacity without moving to a 3B4S case

The LIZARD collection includes different cue case configurations designed for different equipment setups, including compact and larger-capacity cases. (Lizard)

3B4S Pool Cue Case: For a More Complete Setup

A 3B4S pool cue case increases the butt capacity from two to three while maintaining four shaft positions.

This makes it particularly useful for players who carry several different cues.

For example:

Butt 1

Playing cue

Butt 2

Break cue

Butt 3

Jump cue or backup cue

Shafts

Multiple playing or backup shafts

This configuration can be useful for:

• Tournament players
• Serious league players
• Players with playing, break, and jump cues
• Players who want room for their equipment to grow
• Players who prefer carrying their complete setup in one case

A 3B4S case is also commonly referred to as a 3x4 pool cue case.

LIZARD currently offers several 3B4S models, including the Coco, Scarab and Aegis series. (Lizard)

---

2B3S vs 2B4S vs 3B4S

Here is a simple way to compare the three configurations:

Configuration	Cue Butts	Shafts	Typical Setup
2B3S	2	3	Playing + break cue
2B4S	2	4	Playing + break cue + extra shafts
3B4S	3	4	Playing + break + jump/backup cue

The right configuration depends less on what looks impressive and more on what you actually carry.

Which Pool Cue Case Size Is Best for You?

Instead of asking:

“What is the biggest pool cue case I can buy?”

Ask:

“What equipment do I actually need to carry?”

That question makes choosing a cue case much easier.

Choose 2B3S if…

You mainly carry:

• One playing cue
• One break cue
• A few shafts
• Basic accessories

You want a compact and practical setup.

---

Choose 2B4S if…

You carry:

• Two cue butts
• Multiple shafts
• Backup equipment
• More accessories

You want additional shaft capacity without significantly increasing the number of cue butts.

---

Choose 3B4S if…

You regularly carry:

• Playing cue
• Break cue
• Jump cue
• Multiple shafts
• Tournament accessories

You want your complete setup organized in one pool cue case.

---

What About a 3B6S Pool Cue Case?

If you have several shafts or a larger collection, you may want to consider a 3B6S pool cue case.

A 3B6S configuration provides:

• 3 cue butts
• 6 shafts

This is more suitable for players who carry a larger equipment setup.

For example, you might have:

• Primary playing cue
• Backup cue
• Break cue
• Multiple playing shafts
• Break shaft
• Additional spare shafts

LIZARD also offers 3B6S configurations, such as the Earl Featherweight Series. (Lizard)

However, more capacity is not automatically better.

If you only carry one cue and one spare shaft, a large 3B6S case may simply add unnecessary weight and bulk.

Don’t Choose a Cue Case Based Only on Capacity

Capacity is important, but it is not the only factor.

Before buying a pool cue case, consider five things.

1. Protection

Your cue case should keep cue butts and shafts separated and secure.

Look for appropriate internal organization and padding rather than judging protection only by the outside material.

2. Accessory Storage

Think about everything you normally carry.

For example:

• Chalk
• Cue glove
• Joint protectors
• Cue extension
• Tip tools
• Cleaning cloth
• Small maintenance equipment

A case with useful accessory storage can make your complete setup much easier to manage.

3. Portability

A larger case can carry more equipment, but it can also become heavier.

If you walk to your local pool hall several times a week, portability may matter more than maximum capacity.

If you regularly travel to tournaments, additional storage and protection may become more important.

4. Your Future Equipment

You should also think about how your equipment may change.

If you currently own one playing cue but expect to add a break cue or jump cue soon, buying a slightly larger case may prevent you from replacing it later.

But avoid buying an extremely large case simply because you might eventually need it.

Choose a realistic amount of additional capacity.

5. Your Playing Style

A casual player, league player, tournament competitor, and cue collector may all need different types of cases.

There is no universal pool cue case size for everyone.

Why the Right Capacity Matters

Choosing the right cue case is not simply about fitting everything inside.

The goal is to keep your equipment:

Protected.
Organized.
Accessible.
Easy to transport.

A case that is too small may force you to overfill compartments.

A case that is much larger than necessary may become inconvenient to carry.

The ideal configuration is the one that gives your equipment enough room without adding unnecessary bulk.

Frequently Asked Questions

What does 2B3S mean on a pool cue case?

2B3S generally means the case is designed to hold two cue butts and three shafts.

What does 2B4S mean?

2B4S generally means two cue butts and four shafts.

What does 3B4S mean?

3B4S means three cue butts and four shafts. It is also commonly described as a 3x4 pool cue case.

Is a 3B4S case better than a 2B4S case?

They are designed for different equipment setups. A 3B4S provides an additional cue-butt position, while both configurations provide four shaft positions.

Is 2B3S enough for a league player?

It can be enough if the player carries a playing cue, break cue, and a limited number of shafts. Players carrying a jump cue or additional equipment may prefer a larger configuration.

Is a 3B4S pool cue case good for tournaments?

A 3B4S configuration can be useful for tournament players who carry a playing cue, break cue, jump cue, and several shafts. The ideal configuration ultimately depends on the player’s equipment.

Should I buy a bigger cue case for future equipment?

A little extra capacity can be useful if you realistically expect your equipment collection to grow. However, an unnecessarily large case can add weight and bulk.

Final Thoughts

Choosing between a 2B3S, 2B4S, and 3B4S pool cue case comes down to one simple question:

How much equipment do you actually carry?

If your setup is simple, 2B3S may be enough.

If you carry multiple shafts, 2B4S provides additional shaft capacity.

If you carry a playing cue, break cue, jump cue, and multiple shafts, 3B4S can provide a more complete setup.

And if your equipment collection continues to grow, configurations such as 3B6S provide even more capacity.

The right pool cue case is not necessarily the biggest one.

It is the one that fits your cues, your shafts, your accessories, and the way you play.
