A 12x24 pool is generally not too small if your goal is lounging, cooling off, and casual family use. However, its suitability depends directly on your lifestyle and how you plan to use it.
An inground swimming pool is generally considered "small" if it measures less than 600 square feet, typically falling between 10×20 feet and 12×26 feet. These compact pools are usually no more than 4 to 5 feet deep and fit into three popular categories based on their design:
Yes, a 12×24 pool is a great size for most backyards. It offers enough room for swimming, exercising, and relaxing without requiring a large footprint. Homeowners choose this size when they want versatility, easier maintenance, and a pool that fits into tighter yard layouts.
For a small backyard, a standard "good" pool size typically ranges from 𝟏𝟎×𝟐𝟎 to 𝟏𝟐×𝟐𝟒 feet, offering roughly 200 to 280 square feet of surface area. This footprint is highly versatile, leaving enough surrounding deck or patio space while still providing plenty of room to cool off, play, or relax.
Inground Pool Dimensions
Vinyl liner pools are typically available in fixed sizes — the most common are 16×32 ft, 18×36 ft, and 20×40 ft. Fiberglass pools are manufactured in molds, so sizes are pre-set by the manufacturer, generally ranging from 10×24 ft up to 16×40 ft.
For example, for a 12' x 24' pool 4 ft. high you would multiply 12 x 24 = 288. Then 288 x 4 = 1,152. Then 1,152 x 7.5 = 8,646 gallons needed.
For an inground pool, the ideal size for a family of four is 16’ x 32’. This footprint provides roughly 100 square feet of swimming space per person, offering plenty of room for general splashing, playing, and floating without feeling crowded.
Large pools typically consume more water and energy, while smaller pools generally require less. Also, consider the materials used and the potential impact on the environment.
A 10x20 pool is not too small if your goal is cooling off, floating, and socializing. However, it is considered too small for swimming traditional laps and can feel crowded if you regularly host large groups. It is an excellent, low-maintenance option for compact backyards.
Pool Size and Volume: The size of a pool affects the amount of heat energy needed to heat it. For example, a large pool (e.g., 20,000 gallons) has more water and more surface area for heat to escape, so it requires large pool heaters and more heat energy. This leads to higher pool heating cost.
For a family of 6, the ideal pool size typically ranges from 𝟏𝟓′×𝟑𝟎′ to 𝟏𝟖′×𝟑𝟔′ for in-ground pools, or 24′24 prime𝟐𝟒′ to 27′27 prime𝟐𝟕′ in diameter for above-ground models. These dimensions provide enough space for everyone to swim comfortably, use large floaties, and play games without overcrowding.
From discounts and lower prices to faster timelines and less competition, fall might be the best time to build a pool! Take a look at these main reasons why you should consider installing your pool during this season.
Choose a Basic Pool Shape
Opting for a rectangular or square pool will help keep costs lower compared to more complex shapes. As you now know, rectangular and square designs are often the cheapest pool shapes. They require fewer materials and less labor, and they offer efficient use of space.
Plants with Sharp or Thorny Leaves
Having sharp, spiky plants like cacti, agave, or certain varieties of Pittosporum around your pool may look stunning, but they can pose a risk, especially for young children or guests running around barefoot. Avoid anything with long, rigid spikes or thorns that could cause injury.
The average residential swimming pool measures 15 to 20 feet wide and 30 to 40 feet long, covering 400 to 600 square feet. Standard depths typically range from 3 feet in the shallow end to 5 or 6 feet in the deep end, holding between 10,000 and 20,000 gallons of water.
If you find a resale house — that is, an existing house that has previously been lived in — with a pool in good shape, you're most likely going to get a better deal than if you install a pool later.
A cowboy pool (also known as a stock tank pool) is a large, galvanized steel livestock tank that has been repurposed into an above-ground swimming pool or soaking tub. They serve as a popular, budget-friendly alternative to traditional in-ground pools.
Best Times to Plan Your Pool Purchase
Late Fall and Winter Typically Offer the Best Discounts: During late fall and winter, pool retailers and contractors experience their slowest seasons, leading to substantial discounts on pools, materials, and equipment.
As seen across this article, competition pools often follow the World Aquatics rules, which establish the standard Olympic swimming pool size as being 50-meters long and 25-meters wide (which extends to 26 meters in temporary pools).
Filling a pool usually takes anywhere from 12 to 48 hours, depending on your pool's size and your hose's flow rate. Divide your pool's gallon volume by your hose's gallons per minute and you'll know your fill time in minutes.
Pool shock is a chemical treatment that helps break down contaminants – such as leaves, dirt and debris, even oils from your skin -- that can gradually build up in your pool water. Shocking your pool as part of your weekly pool maintenance routine will help keep your water clear and balanced.
In-ground pools generally last 20 to 50+ years, but their exact lifespan is heavily dependent on the pool material and regular upkeep. While the structural shell usually outlasts the house, specific components—like liners and finishes—require periodic replacement.
Pools Can Add Value. Inground pools can increase home value by ~5-8% on average (depending on location + market).
