Choosing the Right Pool Size for Your Perth Backyard

One of the trickiest parts of planning a pool isn’t choosing the colour or the range – it’s working out what size will actually fit, and feel right, in your specific backyard. Get it right, and the pool feels like a natural extension of your outdoor space. Get it wrong, and even a beautiful pool can leave a yard feeling cramped or oddly proportioned. Here’s how to think through pool sizing for a typical Perth block.
Start With Your Block, Not the Pool
It’s tempting to start by browsing pool ranges and picking a favourite – but the more useful starting point is your actual backyard. Many established Perth suburbs feature blocks in the 350-450sqm range, which (once you account for the house footprint, driveway, and any existing structures) often leaves a backyard area considerably smaller than people initially picture when they imagine “pool size.” Before looking at specific ranges, it helps to have a rough sense of:
- The usable backyard area once the house, any sheds, and access pathways are accounted for
- Setback requirements from fences and boundaries (these vary by council and affect how close to the edge a pool can sit)
- Any existing features you want to keep - established trees, an alfresco area, a vegetable garden - that will compete for the same space as a pool
The "Leave Room for Living" Principle
A pool that takes up the entire available backyard space can actually make a yard feel smaller, not bigger – because there’s no room left for anything else. Many homeowners find that a pool sized to leave room for a small entertaining area, some garden beds, or even just lawn for kids and pets, results in a backyard that feels more balanced and gets used more, not less.
This is part of why compact and mid-sized ranges have become so popular on standard Perth blocks – they deliver the swimming and lifestyle benefits of a pool, without requiring the entire yard to be dedicated to it.
A Sizing Example: The Byron Series
The Byron Series is a great illustration of how a well-proportioned pool can work on a standard Perth block. Its footprint is designed to fit comfortably within typical suburban backyards – including those in the 350-450sqm block range – while still offering a genuinely useful swimming area for both relaxing and family use.
For homeowners working with a backyard that needs to do double duty (pool, entertaining space, and some garden), starting with a range like the Byron Series and then designing the surrounding space around it often produces a more cohesive result than trying to fit the largest possible pool into the space and seeing what’s left over.
Questions to Ask Yourself Before Choosing a Size
How will you actually use the pool?
Lap swimming, family splashing around, entertaining, or mostly relaxing – each of these has different size implications. A pool primarily for relaxing and cooling off doesn’t need the same length as one intended for serious swimming.
Who’s using it, and how often?
A pool for a young family with small children has different practical considerations (shallow areas, supervision sightlines) than one primarily for adult use.
What else do you want from the backyard?
If outdoor entertaining, garden space, or a play area for kids matters as much as the pool itself, this should factor into how much of the yard the pool footprint takes up.
What’s your realistic access?
Even if a larger pool would technically fit, site access for installation (crane positioning, truck access) can sometimes influence what’s practical for a given block – this is worth discussing early with your pool supplier.
Getting a Second Opinion on Sizing
Because every block is different – and because it’s genuinely hard to visualise how a pool footprint will feel in your specific space just from looking at dimensions on paper – a site visit is one of the most valuable steps in the process. A pool supplier who can walk your actual backyard, take in the existing features, and talk through size options in context will often suggest a sizing approach you hadn’t considered from browsing ranges online alone.
