Perimeter Calculator
Calculate perimeter on map for any shape by placing points around the boundary and closing the loop.
Boundary Measurement Workflow
This tool is useful for site fencing estimates, field borders, and boundary checks where total edge distance is the key metric. Click each corner around the boundary, then switch to area mode if you also need interior size.
When Perimeter Matters Most
Perimeter is often the primary value for projects based on edge length rather than total area. Typical examples include fence runs, cable routes, border trimming, and path loops around parks. Measuring perimeter first helps estimate materials and labor before deeper site modeling.
Field and Lot Boundaries
Trace property edges quickly and compare multiple boundary options before on-site work begins.
Project Estimation
Use the perimeter value as an input for line-based costs, then review area only if required.
FAQ
Can I measure irregular shapes?
Yes. The calculator supports any polygon shape defined by clicked points.
Can I save a perimeter plan?
Yes. Sign in and save the measurement for later edits and comparison.
