Border Wall Comparator Calculator
How does your fence, wall, or linear construction project compare to the US-Mexico border wall? This calculator lets you compare any length and cost to the 3,145 km border (US Bureau of Transportation Statistics) and the $21.6 billion DHS cost estimate (Reuters, 2017). Whether you're fencing your backyard or planning infrastructure, discover how your project stacks up against one of the most discussed construction projects in recent history.
How We Calculate This
Length comparison: your length ÷ reference length. Cost comparison (if provided): your cost ÷ reference cost. Cost per km: your cost ÷ your length. Reference values are user-adjustable.
Frequently Asked Questions
Where does the 3,145 km border length come from?
This figure comes from the US Bureau of Transportation Statistics, representing the total length of the US-Mexico border.
What about the $21.6 billion cost estimate?
This was a DHS internal estimate reported by Reuters in 2017. Actual costs vary significantly based on terrain, materials, and other factors. Other estimates have ranged from $12B to $70B.
Can I compare to other famous walls?
You can adjust the reference values in the assumptions to compare against other structures like the Great Wall of China (~21,196 km) or the Berlin Wall (~155 km).
What is the cost per kilometer of the border wall?
Using the $21.6B estimate over 3,145 km, that's approximately $6.87 million per kilometer. Actual per-km costs vary dramatically based on terrain and construction type.
