If you live in the Chicago area, you know backyard space is precious. Between garages, alleys, decks, and tight lot lines, many homeowners assume a pool just isn’t possible.
The good news? With the right design, even compact city and suburban lots can fit a beautiful, functional inground pool. If you’ve been searching for the best inground pool size for a small backyard in Chicago, this guide will walk you through smart dimensions, layouts, and design tricks that make a small yard feel like a private resort.
What Makes Chicago Backyards Unique?
Before we talk sizes, it helps to think about the typical Chicago (and near-suburb) lot:
- Narrow lots with limited width
- Garages at the back of the property and alley access
- Easements, setbacks, and zoning rules that limit where a pool can go
- Big swings in weather—from hot summers to snowy winters
All of this means your pool design needs to be:
- Efficient with space
- Thoughtful about local setback rules and utilities
- Engineered to handle freeze–thaw cycles
- Planned with multi-use living in mind (dining, grilling, lounging)
A smaller yard doesn’t mean you have to compromise—it just means design matters more.
How to Choose the Best Inground Pool Size for a Small Backyard in Chicago
Start with How You Want to Use the Pool
Instead of asking “What size pool can I squeeze in?” start with “How will we actually use it?”
Common goals:
- Family fun: Kids splashing, playing games, using floats
- Relaxation: Soaking, tanning ledges, built-in benches
- Fitness: Short laps or resistance swimming
- Entertaining: Space for guests, outdoor dining, and maybe a fire feature
Your priorities will guide the length, width, and depth that make the most sense.
Popular Pool Sizes for Small Chicago Backyards
Every yard is different, but here are some sizes that work surprisingly well in tighter spaces:
- 10′ x 20′ – Great for plunge-style pools and compact lots
- 12′ x 22′ – A sweet spot for couples or small families
- 12′ x 24′ – One of the most popular “small yard” sizes
- 14′ x 28′ – Feels generous but still fits many city/suburban lots
These pools are big enough for real swimming and play, but small enough to leave room for:
- A seating area or small patio
- Grill or outdoor kitchen zone
- Walk space around the pool for safety and access
Remember: once setbacks, access paths, and any required fencing are factored in, the finished pool size is usually smaller than the open grassy area you’re looking at now. That’s why a site visit and scaled plan are so important.
Depth: How Deep Should a Small Pool Be?
In a small yard, depth is more important than many people realize.
- 3.5’–5′ depth works best for most families
- You get a comfortable standing zone for adults and kids
- Water stays more usable for games and casual swimming
- Heating costs and construction complexity stay reasonable
Deep ends (8’+) eat up a lot of footprint, can limit where stairs and benches go, and are often less used than people expect—especially in a compact pool. In most small Chicago backyards, a “play pool” depth profile (shallow–slightly deeper–shallow or uniform 4’–5′) makes more sense.
Smart Pool Layout Ideas for Tight Chicago Lots
1. Clean Rectangle Along the Property Line
A simple rectangle tucked along the back or side property line maximizes swim length and leaves open deck space.
- Easy to cover with an automatic cover
- Perfect for lap-like swimming in a small footprint
- Pairs nicely with modern or classic architecture
Common dimensions: 10′ x 20′, 12′ x 24′, 14′ x 28′
2. Long, Narrow “Courtyard” Pool
If your yard is narrower than it is deep, a long, narrow pool can feel dramatic and luxurious.
- Think 8’–10′ wide, 24’–32′ long
- Works well alongside the house or a property line
- Great for adding a row of loungers or a slim dining area opposite the pool
Add a raised wall or water feature on one side to create privacy and block alley views.
3. Plunge Pool with Spa Features
If your yard is very small, consider a plunge pool with built-in spa-style seating and jets.
- Compact dimensions like 8′ x 16′ or 10′ x 18′
- Higher-end finishes and lighting for a “boutique hotel” feel
- Can be heated more easily for shoulder-season use
You still get real water depth and room to move, but the focus is on relaxation and ambiance instead of big laps.
4. Tanning Ledge + Compact Swim Area
A tanning ledge (Baja shelf) is a smart way to make a small pool feel resort-like.
- One-third of the pool is a shallow ledge (12″–18″ deep) for loungers and little kids
- The rest is a slightly deeper area for swimming and floating
- Great for families who want both play space and lounge space in a tight footprint
Example: 12′ x 24′ pool with a 6′ wide tanning ledge and an 18′ swim zone.
5. Integrated Spa Instead of a Larger Pool
For some Chicago backyards, the most satisfying option is a smaller pool plus a dedicated spa, rather than one oversized pool.
- Year-round spa use
- Better use of budget in a tight yard
- Spa can be elevated with a spillover feature, creating sound and visual interest
This combo works especially well when you want a true four-season outdoor experience in a small footprint.
Design Tricks to Make a Small Pool Feel Bigger
Even if you choose a compact size, the right design can make the space feel expansive.
Use Straight, Clean Lines
Rectangular pools and simple geometry look intentional and modern, and they tend to feel larger than they are. Curves can still work, but too many shapes can make a small yard feel busy.
Keep Decking Continuous
Using one main decking material (like pavers or porcelain) ties the whole space together and avoids “patchwork” zones that visually chop up the yard.
Choose Lighter Colors
Lighter deck colors reflect light and feel more open. A slightly lighter interior pool finish can also make the water line visually expand.
Build In Seating
Instead of bulky furniture everywhere, incorporate:
- Built-in benches
- Seat walls
- Ledge seating
These free up floor space while still giving everyone a place to sit.
Use Vertical Space
- Planters, privacy walls, pergolas, and vertical lighting draw the eye upward
- Clever screening hides garages, alleys, or utility areas
This helps the whole area feel like an intimate outdoor room, not just a leftover strip of yard.
Common Mistakes to Avoid in a Small Backyard Pool Project
- Sizing the pool before checking setbacks and utilities – You don’t want to fall in love with a 16′ x 32′ design only to find out zoning cuts it down to 12′ x 24′.
- Trying to do everything at once – Outdoor kitchen, fire pit, dining area, huge pool, big lawn—on a tiny lot. Focus on what you’ll use most.
- Ignoring circulation and walk space – You still need room to walk around the pool safely, access maintenance points, and open covers or gates.
- Overdoing depth in a small pool – Deep ends are fun in theory, but in a compact pool they often reduce usable play space and raise costs.
- Not planning for storage – Floats, toys, cushions, and pool tools need a home. Built-in benches with storage or a small shed can keep the deck clean.

Small Yard, Big Impact — Chicago Lot Pool Size FAQs
What is the best inground pool size for a small backyard in Chicago?
Many small-city and suburban yards work well with pools in the 10′ × 20′ to 14′ × 28′ range, often with depths from 3.5’–5′. The “best” size depends on your setbacks, nearby structures, and how you plan to use the pool.
Can I fit a pool in a 25′ × 40′ backyard?
In many cases, yes. Once setbacks, walk space, and a small patio are accounted for, a compact pool (like 10′ × 20′ or 12′ × 24′) is often possible—but a site visit and survey review are needed to be sure.
Do I need a deep end in a small pool?
Not usually. For most families, a play-pool depth (around 4’–5′) is more practical, more usable, and easier to heat and maintain—especially in a smaller footprint.
Are small pools cheaper than big pools?
Smaller pools typically use less material and may cost less overall, but design, access, soil conditions, and features (like spas, covers, or high-end decking) still play a big role in total cost.
How do I know what layouts are allowed on my lot?
Your property survey and local zoning rules determine where a pool can go. Sunset Pools & Spas can review your survey, check requirements, and suggest sizes and layouts that will work for your Chicago lot.
