Which Pool Sizes Are Most Commonly Chosen?

For many Australian backyards, pools between 6m and 8m provide an excellent balance of swimming space, family recreation and outdoor living. These sizes are among the most commonly selected because they offer versatility while still leaving room for entertaining areas, landscaping and other outdoor features.

They are often considered the sweet spot between compact plunge pools and larger family, entertaining or lap pool designs.

Bigger Isn't Always Better

The best pool size is not always the largest pool that fits. Creating the right balance between the pool, entertaining areas and usable outdoor space often results in a more practical and enjoyable backyard.

Still Comparing Pool Sizes?

If you’re unsure which pool size is right for your backyard, comparing different layouts can help you visualise what works best within your available space.

Explore Pool Types by Lifestyle

While pool size is an important consideration, the best pool often comes down to how you intend to use the space. Some homeowners prioritise family recreation, while others focus on entertaining, relaxation or fitness.

How Much Space Do You Need Around a Pool?

Choosing a pool size is only part of the planning process. Fencing requirements, pool surrounds, landscaping, access pathways and setback requirements all contribute to the total space needed for a successful backyard design.

Understanding these considerations early can help you compare pool sizes more accurately and avoid selecting a design that limits the functionality of your outdoor space.

Understanding Space Requirements

Many homeowners are surprised to discover that the overall space required for a pool is often significantly larger than the pool shell itself. In addition to the pool dimensions, most projects also require space for:
  • Pool fencing and gates
  • Equipment locations and service access
  • Pathways and pool surrounds
  • Outdoor furniture and entertaining areas
  • Landscaping and garden beds
  • Safe access around the pool
  • Minimum setbacks from boundaries and structures
As a general guide, many projects require approximately 1.0m between the pool waterline and the boundary, and around 1.5m between the pool and nearby structures. Requirements can vary between states, councils, certifiers and individual site conditions.

Pool Size Quick Guide

If Your Priority Is... Typical Pool Size
Maximising a Smaller Backyard 4m–5m
Family Recreation 6m+
Outdoor Entertaining 6m+
Exercise & Fitness 10m+
Maximum Swimming & Recreation Space 9m+

Typical Minimum Space Requirements

he examples below provide a simple planning guide based on a typical allowance of approximately 1.0m to a boundary and 1.5m to a nearby structure. Actual requirements vary between sites, councils, certifiers and individual project conditions.

8m 10.5m
9m 11.5m

Width Planning Guide

Pool width often influences how much usable space remains on either side of the pool for pathways, landscaping and entertaining areas.
Pool Width Indicative Minimum Space Required
2.5m 5.0m
3.0m 5.5m
3.5m 6.0m
4.0m 6.5m
4.5m 7.0m

*Based on a typical allowance of approximately 1.0m to a boundary and 1.5m to a structure. Actual requirements vary between sites and approval authorities.

Focus on the Whole Backyard

The best pool is rarely the largest pool that physically fits within the available space. In many projects, retaining adequate room for entertaining, landscaping and everyday backyard use creates a more functional and enjoyable outdoor environment.

For many households, yes. A 6m pool can provide sufficient space for relaxation, cooling off, family recreation and everyday swimming while still preserving valuable backyard space.

Compact pools and plunge pools between 4m and 5m are often well suited to smaller backyards. The most suitable option depends on available space, access requirements and how you intend to use the pool.

Compact plunge pools and smaller family pools are often popular for relaxation, cooling off and creating a private outdoor retreat. The ideal size depends on available space and how you intend to use the pool.

Many families compare pool sizes between 6m and 8m, as these designs often provide a good balance of swimming space, flexibility and everyday use. Larger family pools may be suitable where additional recreation space is desired.

Comparing available space, intended use and surrounding outdoor areas can help determine whether a 6m or 8m pool is more suitable. Visualising both options within your backyard can also make the decision easier.

Many homeowners choose pool sizes between 6m and 8m for entertaining, as these designs often provide a practical balance between swimming space, social interaction and surrounding outdoor living areas. The most suitable size depends on your available space and how you plan to use the backyard.

Longer pool designs, including lap pools and larger family pools, are often preferred for exercise and fitness. The ideal size depends on your available space, swimming goals and intended use.

In addition to the pool shell, space is typically required for fencing, pathways, landscaping, entertaining areas and access around the pool. Setback requirements may also apply depending on your location and approval requirements.

Yes. A pool that occupies too much of the available space can reduce room for entertaining, landscaping and everyday outdoor living. The best pool size is usually one that balances swimming space with the overall functionality of the backyard.

Not necessarily. The best pool size is often the one that creates the right balance between swimming space and the surrounding outdoor environment. A well-planned backyard should allow room for entertaining, circulation and landscaping as well as the pool itself.
