What size are aluminum fence panels?
There is no single universal size.
A residential picket fence, a 6-foot privacy fence, a pool fence, a commercial boundary and an industrial perimeter can all use different panel dimensions.
In the U.S. retail market, common aluminum fence panels are often sold in widths around 6 ft and 8 ft, while common nominal heights include approximately 3 ft, 4 ft, 4.5 ft, 5 ft and 6 ft. Current Home Depot aluminum-fence listings show both 6 ft and 8 ft nominal panel widths and a range of heights from 3 ft through 6 ft.
For factory-manufactured and international project fencing, metric sizes are often more practical.
Wonderful Metal’s current horizontal aluminum slat fence range commonly uses:
- 900 mm
- 1200 mm
- 1500 mm
- 1800 mm
- 2000 mm
for fence height, and:
- 1800 mm
- 2000 mm
- 2400 mm
for panel width, with custom dimensions available.
The correct panel size depends on privacy, security, wind exposure, post spacing, installation method, gate design and local requirements.
This guide explains the most common aluminum fence panel sizes, heights, widths, posts, slats and custom dimensions for residential, commercial and project use.
Quick Aluminum Fence Size Chart
The following table gives a useful starting point.
| Fence Application | Common Height | Common Panel Width |
|---|---|---|
| Low garden boundary | 900–1200 mm | 1800–2400 mm |
| Front yard fence | 1000–1500 mm | 1800–2400 mm |
| Pool fence | Often around 1200 mm+ depending on local rules | 1800–2400 mm |
| Semi-privacy fence | 1500–1800 mm | 1800–2400 mm |
| Full privacy fence | 1800–2000 mm | 1800–2400 mm |
| 6 ft privacy fence | Approx. 1830 mm | Approx. 1800–2400 mm |
| Commercial fence | 1200–2000+ mm | Project-specific |
| Industrial perimeter | 1500–2400+ mm | Project-specific |
| Matching gate | 1200–2400+ mm high | Width customized to opening |
These are design references rather than universal building-code requirements.
Final dimensions should always follow the actual application, local regulations and project engineering.
What Is a Standard Aluminum Fence Panel Size?
A “standard” panel depends on the market.
U.S. Market
Common nominal sizes include:
- 3 ft × 6 ft
- 4 ft × 6 ft
- 4 ft × 8 ft
- 5 ft × 6 ft
- 5 ft × 8 ft
- 6 ft × 6 ft
- 6 ft × 8 ft
Current U.S. retail listings show aluminum panels in common 6-foot and 8-foot widths, with heights including 3, 4, 4.5, 5, 5.9 and 6 ft.
For example, Lowe’s currently lists preassembled aluminum panels at 6 ft high × 8 ft wide for residential decorative fencing.
Metric / International Projects
For Wonderful Metal project and wholesale orders, current horizontal slat systems commonly use:
Height
900 / 1200 / 1500 / 1800 / 2000 mm
Width
1800 / 2000 / 2400 mm
with custom dimensions also available.
Aluminum Fence Height Guide
Fence height affects:
- privacy
- security
- material consumption
- post requirements
- wind load
- appearance
- cost
A taller fence is not automatically better.
The best height depends on the purpose.
900 mm Aluminum Fence
900 mm is approximately 3 ft.
This lower height is commonly useful for:
- decorative gardens
- front landscaping
- low boundaries
- courtyard divisions
- visual separation without blocking views
It provides definition rather than full privacy.
Wonderful Metal currently lists 900 mm as one of the common height options for horizontal aluminum slat systems.
1200 mm Aluminum Fence
1200 mm is approximately 3.9 ft.
This is a versatile size for:
- residential front yards
- garden fencing
- selected pool applications
- decorative boundaries
- commercial landscapes
A 1200 mm fence can offer stronger separation than a 900 mm system while still maintaining relatively open sightlines.
Wonderful Metal’s slat-fence range currently includes 1200 mm as a common production height.
1500 mm Aluminum Fence
1500 mm is approximately 4.9 ft.
This height works well for:
- semi-privacy fencing
- backyards
- villas
- apartments
- courtyards
- commercial boundaries
With closer slat spacing, it can provide meaningful screening without reaching a full 6-foot privacy height.
Wonderful Metal’s black horizontal slat products currently list 1500 mm among their standard-height options.
1800 mm Aluminum Fence
1800 mm is approximately 5.9 ft, commonly treated as a 6-foot fence.
This is one of the most important sizes for privacy fencing.
Common applications include:
- backyard privacy
- villas
- apartment patios
- hotel privacy zones
- commercial screening
- service areas
Wonderful Metal’s horizontal privacy systems frequently use 1800 mm as a common height, and one current Toronto privacy-fence product uses a complete 1800 × 1800 mm panel.
2000 mm Aluminum Fence
2000 mm is approximately 6.56 ft.
This higher fence is useful for projects requiring:
- increased privacy
- stronger visual separation
- commercial screening
- selected institutional applications
However, greater height can increase wind load.
Post size, foundation, profile selection and spacing therefore deserve more attention as fence height increases.
Wonderful Metal’s current horizontal aluminum fence range supports 2000 mm as a common project option.
2400 mm Aluminum Fence
2400 mm is approximately 7.9 ft.
This should normally be treated as a project-specific height rather than a universal residential standard.
Possible applications include:
- industrial screening
- commercial security
- equipment screening
- special privacy requirements
- selected infrastructure projects
At this height, structural considerations become significantly more important.
Wonderful Metal’s current aluminum gate products already use a common height range up to around 2400 mm, showing that taller coordinated fence-and-gate systems can be produced where project requirements justify them.
Aluminum Fence Panel Widths
Panel width determines:
- number of posts
- installation speed
- transport size
- structural behavior
- visual rhythm
Wider panels reduce the number of posts but increase the span between supports.
That tradeoff matters.
1800 mm Wide Aluminum Fence Panel
1800 mm is approximately 5.9 ft.
This is a practical modular width for many projects.
Advantages include:
- manageable panel size
- repeatable installation
- more frequent post support
- convenient residential layout
Wonderful Metal’s Toronto horizontal privacy fence currently uses 1800 mm high × 1800 mm wide panels.
2000 mm Wide Aluminum Fence Panel
2000 mm is approximately 6.56 ft.
This is a useful middle-ground size for:
- privacy fencing
- villas
- commercial landscapes
- contractor projects
It allows longer runs per panel while remaining manageable for international shipment and installation.
Wonderful Metal currently lists 2000 mm as a common horizontal slat panel width.
2400 mm Wide Aluminum Fence Panel
2400 mm is approximately 7.9 ft, close to the common U.S. 8-foot panel width.
This size is efficient for:
- large residential projects
- commercial fencing
- long boundary runs
- distributor stock systems
Current U.S. aluminum panels are frequently sold in nominal 8-foot widths, while Wonderful Metal also lists 2400 mm as a common metric panel width.
6 ft vs 8 ft Aluminum Fence Panels
This phrase can mean either height or panel width, so buyers should be specific.
A 6 ft fence panel may mean:
- 6 ft high
- 6 ft wide
An 8 ft panel normally refers to panel width in many North American product ranges, but 8 ft height also exists for some fencing categories.
Always specify dimensions as:
Height × Width
For example:
1800 mm H × 2400 mm W
or:
6 ft H × 8 ft W
This prevents expensive quotation mistakes.
Aluminum Privacy Fence Panel Sizes
Privacy fencing requires careful coordination of:
- height
- panel width
- slat width
- slat spacing
- posts
A common Wonderful Metal privacy-fence configuration is approximately:
1800 mm H × 1800 mm W
with:
150 × 20 mm horizontal slats
and:
100 × 100 mm posts.
Other Wonderful Metal horizontal systems support slat widths of approximately:
- 60 mm
- 80 mm
- 100 mm
- 120 mm
- 150 mm
with project-specific spacing.
This means two 1800 mm high panels can provide very different privacy levels depending on slat width and gap.
Horizontal Aluminum Slat Fence Dimensions
Wonderful Metal’s current Horizontal Slat Fence system uses the following core sizing framework:
| Specification | Current Common Options |
|---|---|
| Fence Height | 900 / 1200 / 1500 / 1800 / 2000 mm |
| Panel Width | 1800 / 2000 / 2400 mm |
| Slat Width | 60 / 80 / 100 / 120 / 150 mm |
| Slat Spacing | Full privacy / semi-private / open |
| Posts | Aluminum / reinforced options |
| Gate | Pedestrian / swing / sliding |
Wonderful Metal also offers custom dimensions for project orders.
A separate black horizontal product currently lists slat gaps around 20 mm or 30 mm as available standard examples, with custom spacing also supported.
Vertical Aluminum Fence Panel Sizes
Vertical aluminum fencing uses the same basic dimensions:
height × panel width × slat profile × spacing
but the profiles run vertically rather than horizontally.
Wonderful Metal’s current vertical fence range allows customization of:
- fence height
- width
- vertical slat size
- spacing
- post dimensions
- bottom clearance
- installation details.
This means vertical panels do not need to use one fixed factory module.
For B2B projects, the panel should be designed around:
- architectural appearance
- security requirement
- privacy level
- post spacing
- shipping dimensions
Aluminum Slat Widths
Slat width directly changes the appearance and privacy of a fence.
Current Wonderful Metal horizontal-slatted systems offer common profiles around:
60 / 80 / 100 / 120 / 150 mm wide.
A wider 150 mm profile creates a different architectural look from a narrow 60 mm profile.
For example:
60–80 mm slats
can create a more detailed visual rhythm.
100–120 mm slats
provide a balanced modern appearance.
150 mm slats
can create a broad, premium privacy-panel appearance.
One current Wonderful Metal Toronto privacy fence uses 150 × 20 mm slats with 100 × 100 mm posts.
How Does Slat Spacing Affect Fence Size?
Panel size alone does not determine privacy.
Consider two panels:
1800 mm H × 2000 mm W
Panel A:
150 mm slats with almost no visible gaps.
Panel B:
60 mm slats with wide gaps.
They have the same overall dimensions but completely different:
- privacy
- airflow
- light transmission
- material weight
- cost
- wind behavior
Wonderful Metal classifies its horizontal fencing into:
Full Privacy
Minimal visible gaps or closed arrangements.
Semi-Privacy
Controlled sightlines with some airflow.
Decorative Open
Wider spacing for architectural boundaries.
Aluminum Fence Post Sizes
The fence post is as important as the panel.
A beautiful large panel with an undersized post can produce a poor system.
Post size should consider:
- fence height
- panel width
- wind exposure
- privacy level
- installation method
- soil/foundation
- gate loads
Wonderful Metal’s current products include multiple aluminum post sizes depending on system design, and one horizontal privacy system uses a 100 × 100 mm square aluminum post.
Typical Wonderful Metal post-family options across current product ranges include approximately:
- 65 × 65 mm
- 70 × 70 mm
- 90 × 90 mm
- 100 × 100 mm
- 120 × 120 mm
with final selection determined by the particular fence or gate system and project requirements.
Do not choose a post only because its visible dimensions look proportional.
Structural requirements matter more.
Embedded vs Base-Plate Posts
Post length is different from visible fence height.
For an embedded post, part of the post extends into the ground or footing.
For a base-plate post, the post terminates at a mounting plate anchored to concrete or another structural surface.
Wonderful Metal horizontal products currently support:
- surface mounting
- embedded posts
- wall fixing
while other slat systems also support ground mounting, core drilling and base-plate installation.
Therefore, when ordering posts, do not simply say:
“1800 mm post.”
Instead specify:
Fence height: 1800 mm
Installation: embedded
Required post overall length: project-specific
Aluminum Pool Fence Sizes
Pool fence dimensions should not be copied blindly from residential boundary fencing.
Local regulations may specify:
- minimum height
- maximum openings
- ground clearance
- gate direction
- latch height
- self-closing behavior
- climbability restrictions
That means a 1200 mm pool fence suitable in one jurisdiction may not automatically satisfy another.
For international supply, the buyer should provide the applicable local requirement before production.
Visit the Wonderful Metal Pool Fence range for product selection.
Aluminum Picket Fence Sizes
Picket fencing normally uses:
- vertical pickets
- horizontal rails
- posts
- optional spear or decorative tops
Current Wonderful Metal picket and security systems support custom project sizing rather than one universal panel dimension.
For residential, commercial and public-project applications, common fence heights can range approximately from 1200 mm up to 2400 mm, depending on the product and application.
Spacing is equally important because it affects:
- visibility
- child safety
- anti-climb performance
- security
- architectural appearance
Always specify both:
picket dimension + clear spacing
rather than only panel height and width.
Aluminum Fence Gate Sizes
A gate should not simply be made the same width as a fence panel.
Gate dimensions depend on the opening.
Wonderful Metal’s current Aluminum Gate range lists common gate heights around 1200–2400 mm, while width is customized to the driveway or entrance opening.
For sliding gates, width is project-specific and must account for:
- clear opening
- frame width
- overlap
- track or cantilever system
- automation
- support structure
Current Wonderful Metal sliding-gate products support approximately 1200–2400 mm height, with custom widths.
Therefore:
Fence panel width ≠ gate width.
They should be designed together but quoted separately.
Standard Fence Panel Sizes vs Custom Fence Panels
Standardization is useful because it improves:
- manufacturing efficiency
- installation speed
- packaging
- inventory
- replacement
- repeat orders
But custom sizes become valuable when the project includes:
- masonry columns
- irregular boundaries
- architectural drawings
- non-standard heights
- slope changes
- specific privacy requirements
- existing foundations
- custom gates
Wonderful Metal supports OEM/ODM panel dimensions, profiles, spacing, posts, gates, finishes and packaging for project and wholesale supply.
Should You Choose 1800 mm or 2400 mm Panel Width?
This is one of the most common B2B decisions.
1800 mm Width
Advantages:
- smaller span
- easier handling
- more post support
- convenient installation
Disadvantages:
- more posts
- more foundations
- more brackets
2400 mm Width
Advantages:
- fewer posts
- faster coverage
- efficient long runs
- similar to common North American 8 ft modules
Disadvantages:
- larger unsupported span
- potentially higher structural demands
- larger panel handling
The best choice is not determined only by the cost of the panel.
You must compare:
panel cost + post cost + foundation cost + installation labor + structural requirements.
Aluminum Fence Sizes for Residential Projects
For a typical residence, useful starting points are:
Front Yard
900–1500 mm high
Backyard Semi-Privacy
1500–1800 mm high
Full Privacy
1800–2000 mm high
Panel Width
1800–2400 mm
Gate Height
Match fence or architectural requirement
Driveway Gate Width
Customized to vehicle opening
For more residential planning, link to:
Aluminum Fence Sizes for Commercial Projects
Commercial properties often prioritize:
- repeatable modules
- efficient installation
- entrance coordination
- privacy screening
- large project quantities
A commercial project may use:
- 1200–1500 mm decorative boundary fence
- 1800 mm privacy fence
- 1800–2000 mm service screening
- 2400 mm+ special security/screening areas
Dimensions should follow the site’s actual function.
Visit:
Aluminum Fence Sizes for Industrial & Warehouse Projects
Industrial sites frequently require several different fence heights.
An industrial site can include:
- office entrance fence
- warehouse perimeter
- loading yard
- equipment screening
- pedestrian gate
- vehicle gate
The architectural entrance may use aluminum while a higher-security perimeter may use steel.
Wonderful Metal’s Industrial & Warehouse Aluminum Fence page specifically separates these functions.
For taller privacy or industrial fencing, posts and foundations should be selected according to wind load and project engineering rather than simply scaling up a residential system.
Metric vs Imperial Aluminum Fence Sizes
International buyers often encounter both measurement systems.
Useful conversions include:
| Metric | Approx. Imperial |
|---|---|
| 900 mm | 2.95 ft |
| 1200 mm | 3.94 ft |
| 1500 mm | 4.92 ft |
| 1800 mm | 5.91 ft |
| 1830 mm | 6.00 ft |
| 2000 mm | 6.56 ft |
| 2400 mm | 7.87 ft |
| 2438 mm | 8.00 ft |
This matters because:
1800 mm is not exactly 6 ft
and:
2400 mm is not exactly 8 ft.
If a distributor is supplying a market that requires exact nominal 6 ft or 8 ft dimensions, this should be confirmed before manufacturing.
How Many Fence Panels Do I Need?
A simple starting formula is:
Total Fence Length ÷ Panel Module Width = Approximate Number of Panels
For example:
50 meters total length ÷ 2.0 meter panels = approximately 25 panels.
But this is only a preliminary estimate.
You also need to subtract:
- gates
- columns
- corners
- building walls
- irregular sections
and consider post width.
For example, if the visible module consists of:
2000 mm panel + 100 mm post
the real center-to-center layout may differ from simply repeating 2000 mm panels.
Always prepare a fence layout drawing before final production.
Fence Panel Size and Shipping Cost
Panel size affects international logistics.
Large panels can:
- reduce field assembly
- improve installation speed
but may:
- occupy more container volume
- require stronger packaging
- be harder to stack
- increase handling risk
For export orders, sometimes a slightly smaller modular panel can improve container utilization.
This is why distributors should evaluate:
local installation efficiency vs international loading efficiency
rather than copying local retail-panel sizes automatically.
Fence Height and Wind Load
Privacy fencing creates more wind resistance than open picket fencing.
A 1800 mm full-privacy fence can experience considerably different wind forces from an 1800 mm open vertical picket fence.
Important variables include:
- fence height
- panel width
- solid area
- wind zone
- terrain
- post size
- footing
- installation method
This is why a full privacy 2400 mm-wide panel may require different structural treatment from a decorative open panel of the same dimensions.
Final structural design should follow project engineering and local requirements.
Do All Aluminum Fence Panels Use 6063-T5?
No.
This is important for Wonderful Metal’s site because product specifications should not be generalized across every aluminum fence.
Wonderful Metal states that it commonly uses 6063-series aluminum, while the exact alloy, temper, profile size and reinforcement should be selected according to product design and engineering requirements.
Some current horizontal slat systems list 6063-T5 / T6 options, while other product pages may have different specifications.
Therefore, a professional RFQ should specify required performance rather than assuming every panel uses exactly the same aluminum temper.
How to Specify Aluminum Fence Dimensions for a Quote

- container planning
Aluminum Fence Panel Size FAQ
What is the most common aluminum fence panel size?
There is no universal size. In North America, 6 ft and 8 ft panel widths are common retail dimensions. Wonderful Metal commonly manufactures metric widths of approximately 1800, 2000 and 2400 mm for horizontal slat systems.
What is a standard 6-foot aluminum fence size?
A true 6 ft height is approximately 1829 mm. In metric manufacturing, 1800 mm is often used as a practical nominal privacy-fence height.
What width are aluminum fence panels?
Common widths include approximately 1800 mm, 2000 mm and 2400 mm, while North American retail systems commonly use nominal 6 ft and 8 ft widths.
How tall should a privacy fence be?
Many privacy projects use approximately 1800 mm / 6 ft. Some projects use 1500 mm, 2000 mm or taller depending on privacy needs and local rules.
What size posts should I use for an aluminum fence?
The post depends on panel height, span, wind, privacy and mounting method. One current Wonderful Metal privacy system uses 100 × 100 mm posts with 1800 × 1800 mm panels.
Can aluminum fence panels be custom sizes?
Yes. Wonderful Metal’s horizontal and vertical fence ranges support custom height, width, profile size, spacing, posts and gate dimensions.
Is 1800 mm the same as 6 feet?
Not exactly. 1800 mm is about 5.91 ft, while 6 ft is approximately 1829 mm.
Is 2400 mm the same as 8 feet?
Not exactly. 2400 mm is approximately 7.87 ft, while 8 ft equals about 2438 mm.
Are wider fence panels cheaper?
Not necessarily. Wider panels reduce the number of posts but may require stronger structures and can affect packaging, handling and wind performance.
Can fence and gate dimensions be matched?
Yes. Wonderful Metal’s current gate range supports heights around 1200–2400 mm and custom widths so gate profiles, colors and height can coordinate with fence systems.
Choose Aluminum Fence Panel Size by the Whole System
The best aluminum fence panel size is not simply the biggest panel that can be manufactured.
A properly designed fence needs to balance:
height + width + slat size + spacing + post + installation + gate + wind + packaging.
For many Wonderful Metal projects, practical starting sizes include:
Height
900 / 1200 / 1500 / 1800 / 2000 mm
Panel Width
1800 / 2000 / 2400 mm
Horizontal Slat Width
60 / 80 / 100 / 120 / 150 mm
with custom dimensions available according to project requirements.
For a project quotation, provide:
total fence length + panel height + panel width + fence style + slat/picket size + spacing + post type + installation method + gates + color + destination.
Wonderful Metal can then evaluate a suitable modular panel and gate system for residential, commercial, contractor, distributor or project supply.
Contact Wonderful Metal for custom aluminum fence panel dimensions and project pricing.
