You can find the lot size of any Australian property by searching the street address on MapMyLot. The lot area appears in square metres and hectares, and the perimeter in metres, without needing a lot number, account, or title search. This works across Queensland, New South Wales, Victoria, Tasmania, and the ACT.

Find my lot sizeLot size comes up in several common situations: renovation planning (understanding the footprint available for a deck, pool, or extension), development feasibility (checking minimum lot size against council requirements for subdivision), property investment (comparing land content across listings), and landscaping or fencing quotes (perimeter measurements directly from the boundary). Knowing the lot size from a street address - without ordering a title search - saves time and money for quick reference checks.
When you search an address and tap the boundary polygon, MapMyLot displays:
With a Pro subscription ($19.99/month), you also get individual segment lengths for each boundary side - useful for fencing contractors and landscapers who need to quote specific sections of the boundary.

Lot size (also called land area or block size) is the area of the land parcel - the ground footprint including garden, driveway, and any built structures. It is the cadastral boundary area. Floor area is the total area of the buildings on the lot. MapMyLot shows lot size from the cadastral boundary polygon, not floor area. Floor area data is not publicly available in cadastral datasets.
Real estate listings often quote both land area and house size. The "land area" figure on a listing typically matches the cadastral area, which is what MapMyLot shows. The house size is a separate measurement from building records or the sales agent.
Search your street address on MapMyLot to see the lot area in square metres and hectares, plus the boundary perimeter in metres. The data comes from official government cadastral sources for each state and no lot number is required.
MapMyLot currently covers Queensland (3.32M parcels), New South Wales (4.89M parcels), Victoria, Tasmania, and the ACT. Western Australia and South Australia are not yet included.
Lot size (also called land area or block size) is the area of the land parcel itself - the ground footprint including yard, garden, and driveway. Floor area is the total area of the buildings on the lot. MapMyLot shows lot size from the cadastral boundary, not floor area.
Small differences of a few square metres are normal due to differences in how area is calculated (cadastral polygon vs survey plan). Larger differences may indicate a subdivision or consolidation that has not been updated in one of the data sources. The cadastral area in MapMyLot comes from the government spatial dataset, which is updated regularly but may lag survey plan registration by weeks to months.
