Vinyl and aluminum solve different problems, so the short answer is a question: does the owner want to block the view or keep it? Vinyl privacy panels build a solid wall. Aluminum builds an open picket line that contains without hiding anything. Price is not the main divider here; purpose is.
The example math at 4 ft
Both fences share a 4 ft height in our example rates, so that is the clean comparison for a 100 ft run:
| Fence | Example rate | 100 ft total |
|---|---|---|
| Vinyl, 4 ft | $32 / linear ft | $3,200 |
| Aluminum, 4 ft | $48 / linear ft | $4,800 |
At the example rates, aluminum runs $16 more per foot. Even 6 ft vinyl privacy ($42 per foot in the examples) comes in under 4 ft aluminum, so the guess that metal must cost less gets the math backwards. These are example rates; run the real ones on the vinyl fence calculator and the aluminum fence calculator.
Wind load is the sleeper issue
A solid vinyl panel is a sail. Every gust loads the posts and footings, and on open, windy sites that means deeper footings, tighter post spacing, or a fence that eventually leans. Aluminum pickets let wind pass through and barely notice a storm. If the run sits on an exposed ridge or an open field line, that difference belongs in the design and the quote, not just the material conversation.
Pools, kids, and sightlines
Aluminum is the default around pools for a reason: open pickets keep the water visible from the house, splash and chemicals do not bother it, and standard panel styles line up well with common pool barrier requirements. Heights and gap rules vary by jurisdiction, so check the local code before you quote. Vinyl privacy around a pool trades that visibility for seclusion. Some owners want exactly that, but it should be a deliberate choice, not an accident.
Which fence fits which yard
Backyard privacy from close neighbors: vinyl, and go 6 ft. Pool enclosures, front yards, view lots, windy exposures: aluminum. Both are low-upkeep compared to wood, so maintenance rarely decides this one. Sightline and wind do. Price either by the foot with gates as their own lines, the method in how to price a fence job.
