TL;DR
Plan for the pool footprint plus at least 50 cm of clear, non-slip walkway on all sides, and confirm the surface can carry the water: roughly 1 tonne per cubic meter. Inflatable Pool Factory round pools span 2–10 m diameter and rectangular pools start at 2 × 2 m.

The Problem
Buyers often measure only the pool diameter, then discover there is no room to walk around it, no safe entry point, and no drainage route — or worse, the surface cannot carry the filled weight.
The Solution
Measure the usable area, subtract clearance, check the load, and pick the largest pool that fits with margin. A pool that fits properly is safer, easier to maintain, and more pleasant to use than the biggest pool you can squeeze in.
Step by Step
- Measure the usable area in both directions — a tape outline on the ground beats estimating
- Subtract 50 cm clearance per side for walkways, a ladder, and safe entry/exit
- Estimate the water load: length × width × intended water depth gives cubic meters; water weighs about 1 tonne per cubic meter
- Example: a 4 m round pool filled to 1.0 m holds roughly 12 m³ of water — around 12 tonnes
- Confirm the surface is level; a slope causes uneven water line and wall stress
- Plan the fill source and, critically, a drainage route for the drain valve
- Match the size to your space: Ø 2–3 m fits small patios; Ø 4–5 m suits typical gardens; 6 m and up needs open lawn
Frequently Asked Questions
How close can a pool be to a fence or wall? ▼
Keep at least 50 cm so you can walk around, clean, and inspect the walls. Local barrier rules may also require pool-to-fence distances — check before you buy.
Can I put a pool on a balcony or roof terrace? ▼
Only after a structural load check by a qualified engineer. A filled pool concentrates several tonnes in a small area — most balconies are not designed for that.
Does a bigger pool need more chemicals and filtration? ▼
Yes. Water volume drives chemical demand, filter run time, and fill/drain time. Sizing the pool to your real usage keeps maintenance manageable.
