Frequently Asked Questions
What is the standard fence panel size in the US vs UK?
US fence panels are typically 8 feet (2.44 m) wide. UK fence panels are 6 feet (1.83 m) wide — the most common UK garden fence size. Australian panels are usually 1.8 m (about 6 ft) wide. Post spacing matches panel width: center-to-center spacing equals the panel width, placing posts at each end and junction.
Do I need a permit to build a fence?
In the US, most municipalities require a permit for fences over 6 ft or those on front yards. Always check local zoning codes. In the UK, planning permission is required for fences over 2 m (6.5 ft) high, or over 1 m if next to a highway. In Australia, requirements vary by state — check your local council. In Canada, municipal bylaws vary widely.
