The tool
What information does it use?
- Enclosure length: The fenced area, not the pool itself.
- Enclosure width: enter a measured or verified value
- Fence style: Aluminum, vinyl, wood, glass, or removable mesh.
- Price per linear ft: Installed.
- Number of gates: enter a measured or verified value
- Cost per gate: Self-latching, self-closing.

The relationship
The formula in plain English
Fence length = 2 × (enclosure length + width); total = fence + gates
Codes generally require ≥4 ft height with a self-closing, self-latching gate.05
Worked through
A worked example: 50 × 40 ft enclosure, aluminum, 1 gate
- Fence length = 2 × (50 + 40) = 180 ft
- Fence = 180 × $25 = $4,500
- + 1 gate at $300 = $4,800 total
| Enclosure | Fence length | Fence cost | With gate |
|---|---|---|---|
| 40 × 30 ft | 140 ft | $3,500 | $3,800 |
| 50 × 40 ft | 180 ft | $4,500 | $4,800 |
| 60 × 40 ft | 200 ft | $5,000 | $5,300 |
| 60 × 50 ft | 220 ft | $5,500 | $5,800 |

Common questions
Frequently asked questions
How much fencing do I need for a pool?
Measure the area you intend to enclose — not the pool itself — and take its perimeter: twice the length plus width for a rectangle. That's the linear footage of fence. Add gates separately. A 50-by-40-foot enclosure needs 180 linear feet of fence plus one or more self-closing gates.
What are pool fence code requirements?
Requirements vary by jurisdiction, but most follow the model that a barrier must be at least four feet high, have no gaps or footholds a child could use to climb, and include a gate that is self-closing and self-latching with the latch placed out of young children's reach. Always confirm your local code.
What's the best pool fence material?
Aluminum is durable, low-maintenance, and economical; vinyl needs little upkeep; wood offers privacy but more maintenance; glass panels preserve views at a premium price; removable mesh suits families wanting seasonal flexibility. The right choice balances safety, looks, budget, and maintenance.
Does a pool gate have to self-close?
In virtually all pool-barrier codes, yes. The gate must swing shut and latch on its own so it can't be left open accidentally, and the latch must sit high enough or be designed so young children can't release it. Self-closing, self-latching hardware is a core safety requirement, not optional.
How much does a pool fence cost?
It depends on length, style, and gates. Installed prices range widely — economical aluminum or mesh at the lower end to glass panels at the high end per linear foot — plus a few hundred dollars per gate. The calculator multiplies your enclosure perimeter by the per-foot price and adds the gates.
How tall does a pool fence have to be?
Most codes require at least 4 feet, with a self-closing, self-latching gate — check local rules.
How many linear feet of pool fence do I need?
The perimeter of the area you're enclosing: 2 × (length + width) of the enclosure.
Do pool gates need to self-latch?
Yes — nearly all codes require self-closing, self-latching gates with the latch out of children's reach.
