Splitting a plot into smaller lots sounds simple until the plot isn't a perfect rectangle — which real parcels almost never are. Doing this by hand means computing the polygon's actual orientation, then working out where each dividing line needs to fall to get genuinely equal areas, not just equal-looking widths. Parcel Splitter does this from an uploaded boundary in a few clicks.

What you need before you start

A single polygon representing the parcel boundary — GeoJSON, Shapefile (zipped), GeoPackage, KML/KMZ, or a spreadsheet with coordinates. One connected polygon without holes; multi-part parcels or parcels with interior rings aren't supported yet.

The split direction is chosen from your parcel's own shape — the long edge of its minimum rotated bounding rectangle — not an arbitrary north-south default. That gives sensible strips even on a rotated or irregular parcel. You can still override the angle manually before splitting if you want a different orientation.

The three ways to split

  1. Equal Parts

    Pick a number of lots, and the parcel splits into that many pieces of genuinely equal area — accounting for the parcel's real shape, not just dividing its width evenly.

  2. Fixed Width

    Set a strip width and the parcel divides into consistent-width strips, with the final strip absorbing whatever area is left over.

  3. Target Area

    Set one specific area and get repeated lots of exactly that size — useful when each plot needs to meet a minimum size requirement.

Upload, preview, split

Upload your boundary file, and the tool shows a suggested split angle based on the parcel's shape. Choose your mode (Equal Parts, Fixed Width, or Target Area), confirm or adjust the angle, and run the split. Each resulting lot comes back labeled with its exact computed area in square meters, ready to export as GeoJSON, Shapefile, or KML.

Coordinate systems handled automatically

Whatever coordinate system your source file is in, the parcel is automatically reprojected to an accurate local metric projection before splitting — so the areas and widths that come back are correct in real-world units, not distorted by an unsuitable projection.

Not a substitute for approval-ready subdivision plans. This tool handles the geometry accurately, but doesn't account for local setback rules, road access requirements, or development authority byelaws — those vary by jurisdiction and need real planning work. Our team handles that when you need a compliant, approval-ready layout.
