How to measure a property’s perimeter
This page opens in area mode with each side’s length written on the map in feet and the fence panel open. Search for the address’s town or paste coordinates, zoom right in on the yard, and tap each corner of the area in order around it: house corners, fence corners, the ends of a driveway. After three corners the outline closes and the perimeter appears under the area, with the length of every side in the table and on the map.
Drag a corner to line it up with a fence post or a property marker you can see in the map. Tap the dot halfway along a side to add a corner where the line bends, and use Undo if a tap lands wrong.
Fence length and posts
The perimeter is the length of fence for the whole outline. The fence panel splits each side into sections no longer than the spacing you type, puts a post at every corner and counts the posts: a 100 by 50 ft yard at 8 ft spacing has 13 sections on each long side and 7 on each short one, 40 posts in all. It starts at 8 ft; set it to your panel or rail length (in metres if you measure in metres). Gate posts and bracing aren’t included, so add them for each gate.
If only part of the yard gets a fence, switch to Distance and trace just that run: the total is the fence length, and the segment table lists each straight run.
Before you build
A map is good for planning and quotes, but fences sit on legal lines. Check your plat or survey for the boundary and setbacks, and call before you dig so buried lines get marked. Download the outline as KML or GeoJSON to send to a contractor, or share a link to the drawing.
